Countersunk SD Screws Bimetal 316 Stainless

Countersunk SD Screws Bimetal 316 Stainless

Countersunk Philips SD bimetal screws feature heat treated hardened carbon steel drill tips. The head and threaded body are a 316 stainless steel grade. This provides the ultimate corrosion resistance in a self drilling screw whilst still maintaining drilling performance.

These bimetal screws have a dual layer Ruspert surface coating therefore the surface will not appear to have a typical stainless steel look. This is simply part of the manufacturing process ensuring a high level of corrosion protection.
