Professional Applications & Engineering Value

These 410 stainless steel tapping screws deliver exceptional engineering value in plastic fastening applications where material integrity and corrosion resistance are critical. The thread cutting design (Type 25/BT) eliminates the need for pre-tapped holes, reducing installation time and labor costs while creating strong, permanent threads in thermoplastic materials. The Phillips pan head configuration provides a low-profile finish with excellent drive engagement, preventing damage to surrounding components. With fully threaded construction and precise 20 TPI spacing, these screws distribute clamping force evenly, preventing stress concentration points that can lead to plastic fatigue or failure. The combination of corrosion-resistant 410 stainless steel and regulatory compliance makes these fasteners ideal for electronics enclosures, automotive plastic components, and outdoor equipment where environmental exposure is a concern.

Specification Summary & Compliance

This No. 6 x 5/16" tapping screw features a 0.138" thread diameter with 20 threads per inch precision and Class 2A thread tolerances for consistent performance. The screw follows standard Type 25/BT thread cutting specifications for plastic applications, requiring a No. 31 drill bit (0.12" diameter) for proper hole preparation. Manufacturing and material compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and market acceptability for industrial applications.
