S-92400A290 Length 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Superior thread retention in plastics thanks to the tri-lobe shank design that creates strong, permanent threads without pre-tapping
• Enhanced corrosion resistance with zinc-plated steel construction for long-lasting performance in various environments
• High-torque installation capability through the external hex drive design that prevents cam-out and ensures secure fastening
• Optimized for plastic substrates with thread forming technology that minimizes stress cracking and material damage
• Full-length threading provides maximum grip strength and uniform load distribution along the entire fastener length
• Precision compatibility with No. 21 drill bits (0.159") for streamlined installation processes and reduced assembly time
• Regulatory compliance assurance meeting RoHS 3 and REACH standards for environmentally responsible manufacturing

Professional Applications & Engineering Value

This No. 10 TRS tapping screw delivers exceptional engineering value for plastic assembly applications where traditional fasteners often fail. The zinc-plated steel construction provides necessary corrosion protection while maintaining the strength required for durable connections. The innovative tri-lobe shank design revolutionizes plastic fastening by displacing material during installation to form precise mating threads, eliminating the need for additional tapping operations and reducing assembly costs. The external hex drive ensures reliable torque transmission without stripping, while the 14 TPI thread pitch offers optimal thread engagement in various plastic densities. These thread forming screws are particularly valuable in electronics enclosures, automotive plastic components, and consumer products where vibration resistance and long-term reliability are critical.

Specification Summary & Compliance

This 1/2" TRS tapping screw features precision inch system dimensions including a 0.312" hex head width and 0.151" head height for standard tool compatibility. The fastener maintains Class 2A thread tolerances with a 0.19" thread diameter and right-hand threading configuration. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental responsibility and workplace safety. The flange diameter of 0.414" provides additional bearing surface for improved load distribution in plastic applications.
