S-91675A357 Length 3/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 410 Stainless Steel construction for long-lasting performance in demanding industrial environments
• Enhanced installation efficiency through external hex drive design providing secure tool engagement and high torque capability
• Increased holding power with flanged head design that distributes clamping force over wider surface area
• Reduced assembly steps using thread forming technology that creates strong, permanent threads without tapping operations
• Optimized for sheet metal applications with pointed tip and precise thread geometry for smooth penetration into 0.025" maximum thickness materials
• Reliable thread engagement with fully threaded shank and 12 threads per inch configuration for consistent fastening performance
• Environmental compliance assurance meeting RoHS 3 and REACH standards for safe use in regulated industries

Professional Applications & Engineering Value

These No. 10-12 x 3/4" tapping screws deliver exceptional engineering value in sheet metal fabrication and assembly operations. The 410 Stainless Steel composition provides excellent resistance to corrosion and oxidation, making these thread forming screws ideal for applications exposed to moisture, chemicals, or outdoor elements. The flanged hex head design eliminates the need for separate washers while providing superior clamp load distribution, preventing material deformation in thin-gauge metals. With their fully threaded pointed tip and precise external hex drive, these screws create strong, permanent threads in pre-drilled holes using a standard No. 21 drill bit (0.159"), streamlining installation while maintaining joint integrity in HVAC systems, electrical enclosures, automotive components, and industrial equipment where vibration resistance and long-term reliability are critical.

Specification Summary & Compliance

This No. 10 tapping screw features a 0.19" thread diameter with 12 threads per inch and 3/4" length, manufactured to precise dimensional standards for consistent performance. The thread forming design (Type A/AB) creates strong mating threads in ductile materials without chip removal. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations ensures environmental safety and restricted substance management. Designed for use with No. 21 drill bit (0.159") in materials up to 0.025" thickness, these industrial fasteners provide reliable performance in demanding sheet metal applications.
