Professional Applications & Engineering Value

This Type B thread forming screw delivers exceptional value in sheet metal fabrication and industrial assembly where environmental sealing is critical. The 18-8 stainless steel composition provides inherent corrosion resistance, while the fully threaded blunt tip design facilitates smooth material displacement during installation. The integrated rubber O-ring creates a reliable seal against moisture, dust, and contaminants, making it ideal for HVAC systems, electronic enclosures, and outdoor equipment. The Phillips pan head configuration offers excellent drive stability, and the thread forming action creates strong, permanent threads without generating chips, eliminating cleanup and ensuring consistent clamping force in thin-gauge materials.

Specification Summary & Compliance

This No. 8-18 x 3/4" tapping screw features precision right-hand threads with 18 threads per inch and 0.164" thread diameter. The fastener is fully threaded with a blunt tip optimized for thread forming applications in sheet metal. Manufactured to industry standards for Type B tapping screws, it requires a No. 29 drill bit (0.136" diameter) for proper hole preparation. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and regulatory acceptance in global markets.
