Professional Applications & Engineering Value

These 410 stainless steel tapping screws are engineered specifically for plastic fastening applications, addressing common challenges like material cracking and weak thread engagement. The Type 25/BT thread cutting design creates precise mating threads in plastic substrates without requiring pre-tapped holes, significantly reducing assembly labor and costs. The fully threaded shank and blunt tip work synergistically to distribute stress evenly, preventing plastic deformation and ensuring vibration-resistant connections in industrial assembly and construction settings. Combined with the Phillips pan head configuration, these screws deliver consistent clamping force while maintaining a low-profile appearance, making them ideal for electronics enclosures, automotive plastic components, and machinery panels where reliability and compliance with RoHS 3 and REACH standards are critical.

Specification Summary & Compliance

These tapping screws feature a No. 10-16 thread with 16 threads per inch and Class 2A thread tolerances, ensuring precise fit in plastic materials. The screws are manufactured to Type 25/BT tapping screw standards with a right-hand thread direction and are designed for use with No. 17 drill bits (0.173" diameter). Compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming they are free of restricted substances and suitable for global industrial applications.
