More details
The tail of the drilling screw is in the shape of drilling tail or sharp tail, without auxiliary processing, you can directly drill, tap and lock on the setting material and basic material, greatly saving construction time. Compared with ordinary screws, the toughness and maintenance force of the drilling screws are higher, and the combination will not loosen for a long time, and the use, safe drilling and tapping are completed at one time, and the operation is simple. So how to install the drill screw correctly?
1, stainless steel drilling screws need special electric drill (recommended power 600W).
2. Adjust the positioner of the electric drill to the appropriate position to ensure that the screw is drilled to the correct position. Check drill speed:
Use 3.5(6#); 3.9 (7 #); # 4.2 (8); When 4.8(10#) 410 screws, ensure that the drill speed is 1800-2500 RPM;
Use 5.5(12#); 6.3(14#) when 410 screws; Ensure that the drill speed is 1000-1800 RPM;
Use 3.5(6#); 3.9 (7 #); # 4.2 (8); When 4.8(10#) 304 screws, ensure that the drill speed is 1500-2000 RPM;
Use 5.5(12#); When 6.3(14#) 410 screws, ensure that the drill speed is 1000-1500 RPM.
3, select the appropriate sleeve or cross head to install on the drill; Then connect the screws.
4, when installing the screw and drill must be perpendicular to the surface of the steel plate; And click the power switch; Force a central point.
5. Add about 13 kg of force to the electric drill by hand; Make sure the force is on the same vertical line as the center point.
6, open the power switch; Can not stop halfway; Stop the trip quickly after the screw is in place (to prevent improper and excessive trip)
