Key Features & Benefits at a Glance
- Superior corrosion resistance with Black-Oxide 18-8 Stainless Steel, ideal for harsh environments and reducing replacement costs.
- Enhanced torque transmission and reduced cam-out thanks to the T10 Torx drive, ensuring reliable installation and minimizing tool wear.
- Strong, secure threads in plastic created by the TRS tri-lobe shank design, which forms durable mating threads without creating chips.
- Consistent, flush seating provided by the rounded pan head, distributing clamp load evenly and improving the finished appearance.
- Full-length threading for maximum grip across the entire 5/16" length, delivering superior holding power in plastic assemblies.
- Compliance with major environmental regulations including RoHS 3 and REACH, ensuring they are safe for use in regulated industries.
Professional Applications & Engineering Value
These No. 4 thread forming screws are engineered to solve common fastening challenges in plastic assembly. The TRS (Thread Rolling Screw) with its tri-lobe shank cross-section displaces material to form strong, clean internal threads, eliminating the risk of chip formation that can cause electrical shorts or mechanical failure. Made from Black-Oxide 18-8 Stainless Steel, they resist corrosion in demanding applications. The T10 Torx drive provides superior torque transfer compared to Phillips or slotted drives, preventing stripping during high-torque installation and speeding up assembly lines. This combination of a thread forming design and a high-performance drive makes them an invaluable, reliable fastener for automotive components, electronics enclosures, and consumer appliances.
Specification Summary & Compliance
This screw is a size No. 4 with a 5/16" length and 20 threads per inch. It features a fully threaded tri-lobe shank and a blunt tip for thread forming applications in plastic, with a recommended drill bit size of No. 37 (0.104" diameter). The fastener is manufactured to standard dimensional specifications for tapping screws and is verified to be RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant.
