Self-drilling hex head screw with fine thread for fastening through mild steel in brackets, components, sections, and assemblies. The fine thread provides greater control and precision compared to coarse thread screws, making it ideal for thicker steel. A hardened tek point drills and taps its own thread without pre-drilling (see drilling capacities). The flanged hex head delivers high pull-out strength, and zinc, Class 3, or Class 4 galvanised finishes ensure suitability for both internal and external applications. Features Fine thread for precise installation Hardened tek point eliminates pre-drilling (see drilling capacities) Flanged hex head for strong clamping and pull-out resistance Available in zinc, Class 3, or Class 4 galvanised finishes Applications Fastening steel brackets, components, sections, and assemblies Suitable for internal and external steel construction projects Downloads Stainless Steel Screws Brochure BiMetal Stainless Steel Screws TDS
