and fine shank to provide maximum grip and minimum strip

the materials to be fastened.

20mm of thread embedment into the chipboard or
wood being fastened to.
3. Fit a #2 Phillips drive bit to a power screwdriver
set to low speed, approx. 1000rpm. |
4. Put screw onto drive bit and
place at fastening position.
5. Push sharply on screwdriver to create a starting
point.
6. Drive screw home until the head is flush with
surface.Note: Colored furniture caps are available
for that perfect finish. |
