Product Description
No.10 Zinc-Plated Raised Countersunk Slotted Self-Tapping Screws
No.10 raised countersunk slotted self-tapping screws manufactured from zinc-plated steel. The self-tapping thread is designed to form a mating thread when installed into a suitable pilot hole in sheet metal, plastics and other appropriate materials.
Also known as an oval countersunk head, the tapered underside locates in a correctly formed countersunk hole while the gently raised top provides a traditional decorative finish. The single-slot drive allows installation with a correctly sized flat-blade screwdriver or driver bit.
