S-92295A103 Length 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Superior holding power in plastic thanks to the Tri-Lobe shank design that forms strong, reliable threads without pre-tapping.
• Enhanced corrosion resistance provided by the black zinc-plated steel finish, ensuring long-term durability in various environments.
• Efficient and secure installation with the Phillips No. 1 drive, reducing cam-out and allowing for high-torque application.
• Optimized for plastic assembly with a thread-forming (TRS) design and blunt tip that minimizes material stress and cracking.
• Full thread engagement along the 1/2" length ensures maximum grip and distribution of load for a secure fastening.
• Precision compatibility with a No. 37 drill bit (0.104" diameter) for accurate pilot holes, streamlining the assembly process.
• Compliance with global standards including RoHS 3 and REACH, making it suitable for regulated industries and international supply chains.

Professional Applications & Engineering Value

This No. 4 x 1/2" TRS thread-forming screw is engineered to address common challenges in plastic assembly, such as material cracking and stripped threads. The Tri-Lobe shank cross-section and thread-forming tapping method displace plastic material to create strong, permanent internal threads without the need for additional inserts, reducing assembly steps and component costs. Made from black zinc-plated steel, it offers excellent resistance to corrosion, which is critical in applications exposed to humidity or harsh conditions. The Phillips drive and standardized pan head design ensure compatibility with common automated drivers, enhancing production line efficiency. Ideal for electronics enclosures, automotive trim, and consumer goods, this screw provides reliable performance where vibration resistance and long-term integrity in plastic materials are paramount.
