The cement board screw includes a head end 12, a nail body or core 14, and a tapered end 16. The head end 12 includes an end face 18 having a driving recess 20 (for example, a star-shaped recess or any other suitable driving recess). The end surface may include a textured surface feature as shown, such as a pattern of recesses or other textures. As used herein, the term nail body refers to the elongated core or shaft of a screw, which can include threaded parts and unthreaded parts. The tapered end 16 is located at an opposite end of the nail body 14 and ends in a sharp point or tip 22. As an example, the cone angle α1 defining the sharp point 22 may be between about fifteen degrees and about twenty-five degrees (such as about eighteen degrees to twenty-three degrees). The tapered end may also include a wedge-shaped cut 15 as shown in the figure. The wedge-shaped cut starts from the tip and extends the entire axial extent of the tapered end.

一高螺紋30在錐形端16上開始（例如，較佳地是略微短於尖端，如藉由圖11中之間距X所描述、或在尖端之處），延伸至釘身14上並沿著釘身終止於一第一軸向位置32。間距X可例如為0.10至0.90英吋的範圍（例如，0.030英吋至0.070英吋、或0.40至0.060英吋)。高螺紋30如圖所示係為一右旋螺紋且具有一周圍邊緣34，形成在一前進齒腹36與一尾接齒腹38相會之處，它們一起界定於約三十五度與約五十五度之間（例如，於四十度與五十度之間）的一高螺紋角α2。於一實施態樣中，高螺紋係不對稱的，具有不同之一前進齒腹角θ1及一尾接齒腹角θ2。特別地，尾接齒腹角小於前進齒腹角，例如，尾接齒腹角可為不超過二十度（例如，於十五度與二十度之間），且前進齒腹角可為不小於二十五度（例如，於二十五度與三十五度之間）。高周圍邊緣34可被界定具有於約0.002“與約0.008”之間的一半徑，在此所述半徑接合螺紋之前進面及尾接面。A high thread 30 starts on the tapered end 16 (for example, preferably slightly shorter than the tip, as described by the distance X in FIG. 11, or at the tip), extends to the nail body 14 and along The nail body ends at a first axial position 32. The spacing X may be, for example, a range of 0.10 to 0.90 inches (for example, 0.030 inches to 0.070 inches, or 0.40 to 0.060 inches). The high thread 30 is shown as a right-hand thread and has a peripheral edge 34, formed where an advancing tooth flank 36 and a tail tooth flank 38 meet, and they are defined together at approximately thirty-five degrees and approximately A high thread angle α2 between fifty-five degrees (for example, between forty degrees and fifty degrees). In one embodiment, the high thread system is asymmetrical and has a different forward flank angle θ1 and a tail-connected flank angle θ2. In particular, the ventral angle of the tail joint is smaller than the ventral angle of the forward tooth, for example, the ventral angle of the tail joint may be no more than twenty degrees (for example, between fifteen degrees and 20 degrees), and the forward ventral angle may be Not less than twenty-five degrees (for example, between twenty-five degrees and thirty-five degrees). The high peripheral edge 34 may be defined to have a radius between about 0.002" and about 0.008", where the radius engages the thread's leading and trailing faces.

螺釘10具有一穿透軸向長度LP，其界定於錐形端16的尖端22與端面18之間。一軸向距離DH界定在錐形端16之尖端22與第一軸向位置32之間。在此，軸向距離DH是螺釘之穿透軸向長度LP的至少百分之七十。然而，變化是可能的（例如，距離DH是長度LP的至少百分之七十五或至少百分之八十）。The screw 10 has a penetrating axial length LP, which is defined between the tip 22 and the end surface 18 of the tapered end 16. An axial distance DH is defined between the tip 22 of the tapered end 16 and the first axial position 32. Here, the axial distance DH is at least 70% of the penetration axial length LP of the screw. However, variations are possible (for example, the distance DH is at least seventy-five percent or at least eighty percent of the length LP).

一低螺紋60於錐形端16上開始（例如，較佳地是略微短於尖端或在尖端之處），延伸至釘身14並沿著釘身終止於一軸向位置62。在此，軸向位置62係實質上相同於第一軸向位置32，且低螺紋之一軸向長度係實質上相同於高螺紋之軸向長度並與其毗鄰。低螺紋60如圖所示係為一右旋螺紋且具有一周圍邊緣64，形成在一前進齒腹66與一尾接齒腹68相會之處，它們一起界定於約五十度與約七十度之間（例如，於五十五度與六十五度之間）的一低螺紋角α4。在一實施態樣中，低螺紋係對稱的，具有兩者皆相同之一前進齒腹角及一尾接齒腹角。A low thread 60 starts on the tapered end 16 (for example, preferably slightly shorter than or at the tip), extends to the nail body 14 and terminates at an axial position 62 along the nail body. Here, the axial position 62 is substantially the same as the first axial position 32, and an axial length of the low thread is substantially the same as and adjacent to the axial length of the high thread. The lower thread 60 is shown as a right-hand thread and has a peripheral edge 64, formed where an advancing tooth flank 66 and a tail tooth flank 68 meet, and they are defined together at about fifty degrees and about seven degrees. A low thread angle α4 between ten degrees (for example, between fifty-five degrees and sixty-five degrees). In one embodiment, the low thread system is symmetrical, having both the same forward ventral angle and a tail connecting ventral angle.

高螺紋30之螺距PH沿著螺紋之長度係實質上同一的（uniform），低螺紋60之螺距PL也是如此，且低螺紋的螺距PL係實質上相同於高螺紋的螺距PH。低螺紋60的每個迴旋（turn）實質上坐落於高螺紋30之相鄰迴旋之間的一軸向中點之處。實質上同一的螺距PH與螺距PL可例如於約0.080英吋與約0.140英吋之間（例如，於約0.100英吋與約0.120英吋之間）。The pitch PH of the high thread 30 is substantially uniform along the length of the thread, the pitch PL of the low thread 60 is also the same, and the pitch PL of the low thread is substantially the same as the pitch PH of the high thread. Each turn of the low thread 60 is substantially located at an axial midpoint between adjacent turns of the high thread 30. The substantially same pitch PH and pitch PL may be, for example, between about 0.080 inches and about 0.140 inches (for example, between about 0.100 inches and about 0.120 inches).

高螺紋30包括一較小直徑（minor diameter）Dm及一較大直徑（major diameter）DMH，且低螺紋60包括相同之較小直徑Dm及一較大直徑DML。沿著釘身14之每一螺紋的高度定義為較大直徑減去較小直徑。釘身14沿著高螺紋及低螺紋係實質上為一直圓柱體（right-circular cylinder），且錐形端16之橫剖面係圓形的，在此橫剖面位在垂直於螺釘軸線50之任何平面中。The high thread 30 includes a minor diameter Dm and a major diameter DMH, and the low thread 60 includes the same smaller diameter Dm and a larger diameter DML. The height of each thread along the nail body 14 is defined as the larger diameter minus the smaller diameter. The nail body 14 is substantially a right-circular cylinder along the high thread and the low thread, and the cross section of the tapered end 16 is circular, where the cross section is at any point perpendicular to the screw axis 50 In the plane.

軸向位置32、62係與頭端12隔開，且釘身14包括在釘身上之一組的反向螺紋80，在此反向螺紋從靠近軸向位置32、62朝向頭端12延展。作為鉸孔螺紋（reaming threads）來操作之反向螺紋80具有一螺旋方向，其與高螺紋及低螺紋的一螺旋方向相反。反向螺紋80具有一較大直徑DMC，其小於高螺紋之較大直徑DMH且大於低螺紋之較大直徑DML。反向螺紋具有一較小直徑Dmc，其大於高螺紋及低螺紋兩者的較小直徑Dm。在此，該組的反向螺紋藉由六條反向螺紋所形成，其中每一反向螺紋螺旋地延伸不超過一百二十圓周度數（circumferential degrees）。然而，具有更多或更少反向螺紋之多樣變化是可能的，例如，該組的反向螺紋可藉由不超過四條反向螺紋所形成，其中每一反向螺紋螺旋地延伸不超過一百二十圓周度數。無論反向螺紋之數量如何，反向螺紋80具有如圖所示繞著釘身之實質上均一的圓周間距。The axial positions 32, 62 are separated from the head end 12, and the nail body 14 includes a set of reverse threads 80 on the nail body, where the reverse threads extend from near the axial positions 32, 62 toward the head end 12. The reverse thread 80 operating as reaming threads has a spiral direction that is opposite to a spiral direction of the high thread and the low thread. The reverse thread 80 has a larger diameter DMC that is smaller than the larger diameter DMH of the high thread and larger than the larger diameter DML of the low thread. The reverse thread has a smaller diameter Dmc, which is larger than the smaller diameter Dm of both the high thread and the low thread. Here, the set of reverse threads is formed by six reverse threads, each of which spirally extends no more than one hundred and twenty circumferential degrees (circumferential degrees). However, multiple variations with more or less reverse threads are possible. For example, the set of reverse threads can be formed by no more than four reverse threads, each of which spirally extends no more than one One hundred and twenty degrees of circumference. Regardless of the number of reverse threads, the reverse threads 80 have a substantially uniform circumferential spacing around the nail body as shown.

如在圖14之端視圖局部橫剖面中最佳可見到，在垂直於螺釘之中心軸線50且沿著反向螺紋之軸向長度的任何給定平面中，每一反向螺紋80的尾接齒腹80A實質上按照線81徑向地延伸，且前進齒腹80B在按照線83之朝向尾接齒腹80A的方向中、從徑向偏離的方向中延伸。於橫剖面之垂直平面中，藉由兩個齒腹80A及80B所圍起之角度φ4係於約三十度與約四十度之間（例如，約三十五度）。As best seen in the partial cross section of the end view of Figure 14, in any given plane perpendicular to the central axis 50 of the screw and along the axial length of the reverse thread, the tail of each reverse thread 80 The tooth flank 80A extends substantially radially according to the line 81, and the advancing tooth flank 80B extends in a direction deviated from the radial direction in the direction of the trailing tooth flank 80A according to the line 83. In the vertical plane of the cross section, the angle φ4 enclosed by the two tooth flank 80A and 80B is between about thirty degrees and about forty degrees (for example, about thirty-five degrees).

頭端係形成為一埋頭（countersunk head）組構，其一截頭圓錐形下部具有複數個凸部（nibs），包括複數個大凸部82及複數個小凸部84，在此多數小凸部如圖所示係設置於連續的大凸部之間。頭端包括一外下部86及一內下部88兩者。外下部86界定一截頭圓錐形錐角φ1，且內下部界定一截頭圓錐形錐角φ2，在此錐角φ1大於錐角φ2。於一實施態樣中，錐角φ1係至少兩倍於錐角φ2。當作範例，φ2可為於六十五度至七十五度之範圍內。The head end is formed into a countersunk head structure, and a frusto-conical lower part has a plurality of nibs, including a plurality of large protrusions 82 and a plurality of small protrusions 84, where most of the small protrusions The part is arranged between the continuous large convex parts as shown in the figure. The head end includes both an outer lower portion 86 and an inner lower portion 88. The outer lower part 86 defines a frusto-conical cone angle φ1, and the inner lower part defines a frusto-conical cone angle φ2, where the cone angle φ1 is greater than the cone angle φ2. In one embodiment, the cone angle φ1 is at least twice the cone angle φ2. As an example, φ2 can be in the range of sixty-five degrees to seventy-five degrees.

小凸部84實質上界定於外下部86上（例如，從頭部周邊延展至內下部88）。大凸部82界定在外下部86及內下部88兩者上。大凸部藉由外下部86上之一第一凸部部分82A及內下部88上之一第二凸部部分82B所界定。第一凸部部分82A及第二凸部部分82B相會並界定於約三十五度與約五十度之間的一內部凸部角φ3。大凸部82具有一同一的圓周間距。複數個大凸部可藉由不超過六個大凸部（例如，彼此隔開九十度的四個大凸部、或彼此隔開一百二十度之三個大凸部）所形成。每一大凸部82包括於一圓角接合部92之處接合下部之一前進面90、及在未形成圓角之一接合部94之處接合下部之一尾接面96。The small convex portion 84 is substantially defined on the outer lower portion 86 (for example, extending from the periphery of the head to the inner lower portion 88). The large convex portion 82 is defined on both the outer lower portion 86 and the inner lower portion 88. The large convex portion is defined by a first convex portion 82A on the outer lower portion 86 and a second convex portion 82B on the inner lower portion 88. The first convex portion 82A and the second convex portion 82B meet and define an inner convex angle φ3 between about thirty-five degrees and about fifty degrees. The large protrusions 82 have the same circumferential pitch. The plurality of large protrusions may be formed by no more than six large protrusions (for example, four large protrusions separated by ninety degrees from each other, or three large protrusions separated by one hundred and twenty degrees from each other). Each large protrusion 82 includes a forward surface 90 where a rounded joint 92 is joined to a lower part, and a tail joint 96 where a joint 94 of a rounded corner is not formed.

This feature helps prevent the screw from over-spinning once the screw is thoroughly penetrated and embedded in the plate.

於一實施例中，高螺紋在反向螺紋區域中的較大直徑DMH2係相同於沿著釘身之其餘部分的較大直徑DMH1。然而，在一替代的實施例中，高螺紋在反向螺紋區域（CTR）中的較大直徑DMH2係大於高螺紋在第一軸向位置32與錐形端16之間之釘身上的較大直徑DMH1。於一實施例中，高螺紋在反向螺紋區域中的較大直徑DMH2係於0.190”與0.205”之間（諸如於0.195”與0.200”之間），且高螺紋在第一軸向位置32與錐形端16之間的較大直徑DMH1係於0.175”與0.195”之間（諸如於0.181”與0.198”之間）。於一實施例中，在反向螺紋區域中的釘身可具有一直徑Dmc，其略微大於直徑Dm，如上面描述之螺釘者。然而，於一例示的實施例中，反向螺紋區域（CTR）具有一較小直徑Dmc，其實質上相等於沿著釘身之其餘部分之高螺紋及低螺紋兩者的較小直徑Dm。In one embodiment, the larger diameter DMH2 of the high thread in the reverse thread region is the same as the larger diameter DMH1 along the rest of the nail body. However, in an alternative embodiment, the larger diameter DMH2 of the high thread in the reverse thread region (CTR) is greater than the larger diameter of the high thread on the nail body between the first axial position 32 and the tapered end 16. Diameter DMH1. In one embodiment, the larger diameter DMH2 of the high thread in the reverse thread region is between 0.190” and 0.205” (such as between 0.195” and 0.200”), and the high thread is at the first axial position 32 The larger diameter DMH1 between the tapered end 16 and the tapered end 16 is between 0.175" and 0.195" (such as between 0.181" and 0.198"). In one embodiment, the nail body in the reverse threaded region may have a diameter Dmc, which is slightly larger than the diameter Dm, such as the screw described above. However, in an exemplary embodiment, the reverse thread region (CTR) has a smaller diameter Dmc, which is substantially equal to the smaller diameter Dm of both the high thread and the low thread along the rest of the nail body.
