Key Features & Benefits at a Glance
- Superior corrosion resistance with zinc-plated steel construction, ensuring long-lasting performance in various industrial environments.
- Effortless installation and reduced assembly time thanks to the Phillips No. 1 drive, providing reliable torque transfer without cam-out issues.
- Excellent thread retention in plastic materials due to the Tri-Lobe shank design, which forms strong, secure threads without pre-tapping.
- Full-length threading and blunt tip for consistent grip and minimized risk of material splitting during insertion.
- Wide compatibility with standard No. 37 drill bits (0.104" diameter), streamlining the setup process for plastic assembly applications.
- Compliance with RoHS 3 and REACH regulations, offering peace of mind for environmentally conscious and regulated industries.
- Durable pan head design with a rounded profile for a flush finish and enhanced aesthetic in finished products.
Professional Applications & Engineering Value
This No. 4 x 1" zinc-plated steel TRS tapping screw is engineered to address common challenges in plastic fastening, such as thread stripping and material fatigue. The thread forming action of the Tri-Lobe shank creates precise, resilient threads in plastic substrates, eliminating the need for additional inserts and reducing assembly costs. With a Phillips drive and fully threaded blunt tip, it ensures quick, secure installations in applications like electronic enclosures, automotive trim, and consumer goods. The zinc-plated finish provides essential corrosion protection, making it a reliable choice for industrial fasteners in demanding environments.
Specification Summary & Compliance
This screw features a thread diameter of 0.112" with approximately 20 threads per inch, adhering to standard thread forming tolerances for consistent performance. It is designed for use with a No. 37 drill bit (0.104" diameter) and complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it meets stringent environmental and safety standards for industrial applications.
