• Easy installation and removal with Phillips No. 2 drive, providing excellent torque transfer and reducing tool slippage.
• Precise fit and reduced assembly time through compatibility with standard No. 23 drill bits (0.154" diameter).
• High thread engagement with 16 TPI right-hand threads, delivering superior pull-out resistance in plastic applications.
• Compliance with global regulations including RoHS 3 and REACH, ensuring safe use in international markets.

Professional Applications & Engineering Value

These zinc-plated steel TRS tapping screws are engineered specifically for plastic fastening applications where traditional screws may cause stress cracking or strip threads. The thread forming technology with tri-lobe shank design displaces plastic material during installation, creating stronger, vibration-resistant threads without chips or debris. The fully threaded No. 8 x 1-1/2" configuration ensures maximum holding power across the entire fastener length, while the pan head with Phillips drive provides a low-profile, secure installation suitable for automated assembly processes. Ideal for plastic components in electronics enclosures, automotive trim, and consumer products, these screws eliminate the need for inserts while maintaining structural integrity in demanding environments.

Specification Summary & Compliance

This No. 8 x 1-1/2" tapping screw features inch system measurements with 16 TPI thread pitch and right-hand threading. Manufactured to precise dimensional standards with Class 2A thread tolerance for consistent performance. The product complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and regulatory acceptance for global industrial applications. Designed specifically for use with No. 23 drill bits (0.154" diameter) in plastic materials.
