Abstract
883,564. Self-tapping screws. ROSAN ENGINEERING CORPORATION. March 10, 1958 [March 8, 1957], No. 7654/58. Class 83 (3). [Also in Group XXV] A self-tapping insert or screw-socket has a screwed bore 12, Fig. 1, closed at the leading end 13 of the insert by a web 25, and slots 17 to provide cutting edges. The full external threads 14 are preceded by similar threads 15 which have truncated crests and a bevelled lead-in 16. The bore 12 has grooves 19 for engagement by a tool to drive the insert. The full threads 14 lock the insert in its bore. In another arrangement, the slots 17 are replaced by circular holes 21, Fig. 3, adjacent the leading end and the insert has a serrated collar 23 to receive a driving tool and subsequently a locking collar.
