S-92525A809 Length 5/16" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 316 stainless steel construction, ideal for harsh industrial environments and outdoor applications.
• Efficient thread forming design creates strong, secure threads in sheet metal without pre-tapping, reducing assembly time and tooling costs.
• Reliable Phillips drive (No. 2) ensures common tool compatibility and prevents cam-out during installation for consistent fastening.
• Pan head with standard rounded profile provides a low-profile, finished appearance and good bearing surface for secure clamping.
• Fully threaded shank maximizes grip length and pull-out strength in sheet metal and other thin materials.
• Precision-matched drill bit size (No. 29) ensures optimal hole fit for the 0.164" thread diameter, preventing material damage and ensuring thread integrity.
• Compliance with RoHS 3 and REACH regulations guarantees environmental safety and unrestricted use in regulated industries and global markets.

Professional Applications & Engineering Value

These Type B thread forming screws are engineered specifically for sheet metal applications, where their 316 stainless steel composition provides exceptional resistance to corrosion from chemicals, saltwater, and industrial atmospheres. The thread forming design displaces material rather than cutting it, creating stronger, tighter threads with zero chip production—eliminating contamination risks in sensitive assemblies. With a Phillips drive and pan head, they offer quick installation using standard tools while maintaining a low-profile finish. Fully threaded from head to tip, these screws ensure maximum engagement in thin-gauge metals, HVAC systems, and electronic enclosures, delivering reliable, vibration-resistant fastening that withstands dynamic loads and thermal cycling.

Specification Summary & Compliance

This No. 8 x 5/16" tapping screw features a 0.164" thread diameter with 18 threads per inch and is fully threaded for consistent holding power. Manufactured to precise dimensional standards with a Class 2A thread fit for reliable engagement. Designed for use with a No. 29 drill bit (0.136" diameter) to ensure proper hole preparation. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, meeting stringent environmental and safety requirements for industrial components.
