Through the above technical solutions, being pressed on wood surface after screw rod is shot in wood materials completely by compression raised line, keeping away
Exempt from screw head rotation to loosen, promotes the stability being connected and fixed.
The utility model is further arranged to: the screw head is provided with multiple compressions close to the periphery of the one side of the screw rod
Convex block.
Through the above technical solutions, being pressed on wood surface after screw rod is shot in wood materials completely by compression convex block, keeping away
Exempt from screw head rotation to loosen, promotes the stability being connected and fixed.
The utility model is further arranged to: the screw head offers multiple indexing troughs, institute far from the screw rod on one side
It states indexing trough and is uniformly distributed setting, and be provided with the mark layer of different colours inside each indexing trough.
Through the above technical solutions, the rotating cycle that mark layer facilitates staff to check that wood screw screws in timber, side
Just adjust wood screw shoots depth.
The utility model is further arranged to: the vertical interval of the adjacent threaded line is 0.5mm, the tapping screw thread
Screw pitch is 3mm.
Compared with prior art, the utility model has the beneficial effects that
By extending to second screw thread in leading portion portion convenient for the starting-up action of wood screw insertion wood materials, with the second screw thread
Structure in different first screw thread reconstruct snail pits, generate with bore screw tracks different before, can reinforce connecting
Stability, and serrated slot opens up the cutting to timber for facilitating the second screw thread, conveniently shoots.
