Screw, machine, countersunk, pozi, zinc plated, GR 4.8, STD, 4 x 0.7 x 12 mm, Fastbolt.

The countersunk screw sits flush with the surface of the material it occupies. These screws typically are used so that you can cover them easily with either a screw cap or piece of wood. Pozidriv head design ensures screwdriver head does not cam-out. Zinc plated fasteners are the most common used plating. This ensures good rust-resisting qualities, appearance and low cost.
