Key Features & Benefits at a Glance
- Exceptional corrosion resistance with 18-8 Stainless Steel construction, ensuring long-term reliability in harsh industrial environments.
- Reliable sealing performance through an integrated rubber O-ring that prevents leaks in sheet metal assemblies.
- Wide temperature tolerance from -40° to 225°F, maintaining seal integrity under extreme operating conditions.
- Efficient thread-forming installation that creates strong, precise threads without pre-tapping, reducing assembly time and tooling costs.
- Secure Phillips drive engagement with No. 2 drive size for controlled torque application and reduced cam-out risk.
- Optimized pan head design providing a low-profile, rounded finish with good bearing surface for consistent clamping force.
- Full regulatory compliance meeting RoHS 3 and REACH standards for environmentally responsible manufacturing.
Professional Applications & Engineering Value
This Type B thread forming screw delivers critical sealing solutions for sheet metal assemblies where environmental protection is paramount. The 18-8 stainless steel construction provides excellent corrosion resistance while the rubber O-ring creates a reliable seal against moisture, dust, and contaminants. The thread forming design eliminates the need for separate tapping operations, reducing installation time and preventing loose threads in thin materials. Engineers specify this Phillips pan head tapping screw for HVAC systems, electronic enclosures, and automotive components where temperature fluctuations from -40° to 225°F demand consistent sealing performance. The combination of fully threaded engagement and blunt tip ensures precise alignment and maximum thread contact for vibration-resistant fastening.
Specification Summary & Compliance
This No. 6-20 x 3/8" tapping screw features standard right-hand threads with approximately 20 threads per inch and 0.138" thread diameter. The screw is fully threaded with a round shank cross-section and requires a No. 32 drill bit (0.116" diameter) for proper installation. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental responsibility and workplace safety standards are met.
