Bi-Metal Self Drilling Screws made of AISI 304 with Steel Drilling Tip

Advantage: The first 3 threads of steel form the thread in the stainless sheet therefore the stainless part of the screw is only in contact with the sheet metal. In addition silver delta seat coating protects the screw against rust.

SUPER Stainless Steel AISI 304 or AISI 316 Self-Tapping Screw

Advantage: Ordinary stainless AISI 304 or AISI 316 is made 3 times harder with a special process. In addition the silver delta seal coating protects the screw against rust. This treatment makes it possible to screw directly into pre-drilled/punched holes in stainless AISI 304 or AISI 316 sheeting. No extra threading is required.
