S-91675A327 Length 3/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 410 Stainless Steel construction, ideal for harsh industrial environments
• Efficient installation through thread forming design that creates strong, permanent threads without chips
• Enhanced grip and stability with integrated flange that eliminates the need for separate washers
• Quick assembly enabled by external hex drive for high-torque application with standard tools
• Maximum thread engagement with full threading and pointed tip for precise alignment in sheet metal
• Optimized for sheet metal applications with specific drill bit compatibility (No. 29) for 0.025" maximum thickness
• Regulatory compliance assurance meeting RoHS 3 and REACH standards for global market acceptance

Professional Applications & Engineering Value

These No. 8-15 thread forming screws deliver exceptional engineering value in sheet metal assembly applications where vibration resistance and material integrity are critical. The 410 Stainless Steel composition provides excellent strength-to-weight ratio while offering reliable corrosion resistance in demanding environments. The thread forming technology creates stronger thread engagement by displacing material rather than removing it, resulting in superior pull-out strength and elimination of loose chips that could compromise electrical components. The flanged hex head design combines the torque capability of external drive with distributed bearing pressure, preventing surface damage to thin-gauge materials while maintaining secure fastening in high-vibration industrial equipment, HVAC systems, and electronic enclosures.

Specification Summary & Compliance

This tapping screw features precise inch measurements with No. 8 screw size, 0.164" thread diameter, and 15 threads per inch configuration. The fully threaded right-hand design with pointed tip ensures consistent performance across the entire 3/4" length. Manufactured to industry standards for thread forming screws (Type A/AB), these fasteners are engineered for use with No. 29 drill bit (0.136" diameter) in materials up to 0.025" thickness. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations ensures environmental responsibility and global market acceptance for your manufacturing operations.
