Professional Applications & Engineering Value

This Type B thread forming screw delivers critical engineering solutions for sheet metal assemblies requiring both mechanical fastening and environmental sealing. The 18-8 stainless steel construction provides excellent corrosion resistance while the thread forming technology creates strong, permanent threads without generating chips that could compromise sensitive equipment. The integrated rubber O-ring creates a reliable seal against moisture, dust, and air infiltration, making it ideal for HVAC systems, electronic enclosures, and outdoor equipment where environmental protection is paramount. The Phillips pan head design offers both aesthetic appeal and practical installation benefits, while the fully threaded shank ensures consistent clamping force across the entire engagement length.

Specification Summary & Compliance

This No. 8-18 x 5/8" tapping screw features precise 0.164" thread diameter with 18 threads per inch and standard Class 2A thread tolerances. The Type B thread forming design follows industry-standard tapping screw specifications, requiring a No. 29 drill bit (0.136" diameter) for proper hole preparation. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental responsibility and global market acceptance. The combination of 18-8 stainless steel material and rubber O-ring sealing creates a comprehensive fastening solution meeting industrial performance requirements.
