S-99512A662 Length 1" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with Black-Oxide Steel coating, extending service life in various environments.
• Maximum holding power in plastics due to the Tri-Lobe shank design, which forms strong, reliable threads without pre-tapping.
• Enhanced torque transmission and reduced cam-out with the T10 Torx drive, ensuring secure fastening and minimizing tool slippage.
• Easy installation and consistent performance with fully threaded, right-hand design and blunt tip for precise placement in plastic materials.
• Wide compatibility with standard No. 37 drill bit (0.104" diameter), simplifying hole preparation and reducing assembly time.
• Durable and reusable threads through thread forming (TRS) technology, maintaining integrity in plastic applications.
• Environmental compliance assurance by meeting RoHS 3 and REACH standards, supporting sustainable manufacturing practices.

Professional Applications & Engineering Value

These No. 4 x 1" TRS tapping screws are engineered to address common challenges in plastic assembly, such as material cracking and thread stripping. The thread forming action of the Tri-Lobe shank displaces plastic material to create strong, permanent threads without generating chips, reducing the risk of contamination and improving joint reliability. Made from Black-Oxide Steel, they offer excellent corrosion resistance, ideal for electronics enclosures, automotive components, and consumer appliances where durability is critical. The T10 Torx drive ensures high torque application with minimal wear, while the pan head provides a low-profile, secure fit. Fully threaded for consistent grip, these screws deliver reliable performance in plastic applications, enhancing productivity and reducing maintenance needs.

Specification Summary & Compliance

This product features a thread diameter of 0.112" with approximately 20 threads per inch, a pan head style, and a length of 1". It is designed for use with a No. 37 drill bit (0.104" diameter) and complies with industry standards for thread forming in plastics. The screws are fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe and sustainable use in various industrial settings.
