Self Drilling Screws

Self Drilling Screws

Unless 18-8 Stainless is specifically required, Fastener SuperStore recommends using 410 Stainless Steel for corrosion-resistant Self-Drilling Screws. 410 Stainless Steel Screws are heat-treated and hardened, which allows them to drill more effectively. 18-8 Stainless Steel Screws are not heat treated and therefore do not provide the same drilling capacity.
