S-97349A428 Length 3/8" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ensuring long-term reliability in humid or demanding environments
• Efficient thread forming design creates strong, permanent threads in plastic materials without pre-tapping, reducing assembly time and tooling costs
• Optimized Phillips drive system (No. 2 size) provides secure torque transmission and prevents cam-out during installation
• Fully threaded shank delivers maximum grip length and uniform stress distribution across the entire engagement area
• Pan head profile with standard rounded edges offers a clean finished appearance while preventing surface damage to plastic components
• Precision-matched drill bit specification (No. 29/0.136") ensures proper hole sizing for optimal thread engagement and holding power
• Environmental compliance assurance with RoHS 3 and REACH standards, making them suitable for regulated industries and international markets

Professional Applications & Engineering Value

These 18-8 stainless steel tapping screws are specifically engineered for plastic assembly applications where corrosion resistance and thread integrity are critical. The DST thread forming technology creates precise mating threads through material displacement rather than cutting, eliminating chips and preventing stress concentrations in brittle polymers. The Phillips pan head design combines installation efficiency with a low-profile appearance ideal for consumer products, electronic enclosures, and automotive trim components. Manufactured from grade 18-8 stainless steel, these fully threaded screws maintain their mechanical properties in temperature-variant environments while providing excellent resistance to chemicals and oxidation. The right-hand threaded configuration with blunt tip ensures straightforward alignment and prevents cross-threading during high-volume assembly operations.

Specification Summary & Compliance

This No. 8 x 3/8" tapping screw features standard inch measurements with fully threaded configuration and 18 threads per inch precision. The fastener conforms to DST screw type specifications for plastic materials with recommended No. 29 drill bit (0.136" diameter) for proper installation. Manufacturing and material compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring restriction of hazardous substances for environmental safety and international market acceptance.
