Original cap & washer combination for size #6, #8, M3 and M4 fasteners with round head, pan head or countersunk heads.
8/8 Snap-Caps are comprised of a cap and base washer. The screw is secured into the base washer and the cap "snaps" on. Snap-Caps provide a secure seal and can help protect the fastener head while preventing rust and corrosion. 64 colors are available. 8/8 Snap-Caps screw covers have an outside diameter of 1/2" and work with screw sizes from #6 and #8 screws (and metric sizes M3 and M4).
