S-99512A651 Length 2" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction for extended service life in demanding environments
• Maximum torque transfer and reduced cam-out with T30 Torx drive for reliable installation and worker safety
• Strong, permanent threads in plastic created by the TRS thread-forming design, eliminating the need for pre-tapped holes
• Exceptional pull-out and vibration resistance from the tri-lobe shank design that ensures a secure, lasting hold
• Full 2-inch thread engagement provides maximum holding power and distribution of stress in assembled materials
• Streamlined installation process with a blunt tip and standard pan head for easy alignment and consistent seating
• Compliance with major environmental directives including RoHS 3 and REACH, ensuring safety and regulatory acceptance

Professional Applications & Engineering Value

These 1/4" Zinc-Plated Steel TRS Tapping Screws are precision-engineered to solve common fastening challenges in plastic assembly. The thread-forming TRS design with its tri-lobe shank displaces material to create strong, clean mating threads without chipping or cracking brittle plastics, providing a superior alternative to thread-cutting screws. The T30 Torx drive ensures high torque transmission, minimizing the risk of driver slippage and head stripping, which is critical for assembly line efficiency and product integrity. This combination makes them an ideal plastic fastener for enclosures, automotive components, and electronic housings where vibration resistance and a reliable, long-term hold are paramount.

Specification Summary & Compliance

This screw adheres to a 1/4" diameter with 10 threads per inch and a 2" length, featuring a right-hand thread and Class 2A thread fit for consistent performance. The pan head style with a T30 Torx drive and blunt tip is designed for use with a specified A drill bit (0.234" diameter). Manufacturing and material compliance is confirmed with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations.
