Professional Applications & Engineering Value

These 410 Stainless Steel tapping screws deliver exceptional engineering value in sheet metal applications where corrosion resistance and structural integrity are paramount. The thread forming technology eliminates the need for separate tapping operations, reducing assembly time while creating strong, strip-resistant threads in metal substrates. The Phillips flat head design with 82° countersink angle ensures flush mounting in HVAC systems, electrical enclosures, and metal fabrication projects. With full threading and right-hand direction, these No. 10-12 TPI screws provide maximum engagement in thin-gauge materials, preventing loosening from vibration and thermal cycling. The combination of 410 stainless steel material and precise dimensional control makes these fasteners ideal for outdoor equipment, industrial machinery, and architectural metalwork where durability and professional finish are critical requirements.

Specification Summary & Compliance

These tapping screws feature precision No. 10-12 thread with consistent 12 TPI spacing and fully threaded design for optimal performance. The flat head configuration includes standard profile with 0.362" diameter and 82° countersink angle for proper seating in prepared holes. Manufactured as Type A/AB thread forming screws with pointed tip for easy starting, these fasteners comply with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring they meet international standards for industrial fastener applications.
