S-90417A124 Length 5/16" Tapping Screws

Key Features & Benefits at a Glance

• Superior holding power in plastic materials thanks to the Tri-Lobe shank design that creates secure, vibration-resistant threads
• Enhanced corrosion resistance provided by the Black-Oxide Steel finish, extending service life in various industrial environments
• Efficient, high-torque installation enabled by the Phillips No. 2 drive, reducing cam-out and tool slippage
• Reduced risk of material cracking with thread forming technology that displaces rather than removes plastic material
• Full-length thread engagement for maximum grip strength across the entire 5/16" length in plastic assemblies
• Simplified installation process with pre-drilling guidance for 1/8" drill bits and blunt tip design for precise starting
• Compliance with international safety standards including RoHS 3 and REACH for use in regulated industries

Professional Applications & Engineering Value

These No. 6 TRS tapping screws are specifically engineered for plastic fastening applications where material integrity is paramount. The thread forming technology, combined with the unique Tri-Lobe shank cross-section, creates strong, permanent threads in plastic substrates without generating chips that could contaminate sensitive assemblies. This design prevents stress concentration points that often lead to cracking in brittle plastics. The Black-Oxide Steel construction provides sufficient corrosion protection for indoor industrial environments while maintaining the mechanical strength needed for durable connections. The Phillips drive offers reliable torque transfer during installation, making these screws ideal for high-volume production lines in electronics enclosures, automotive trim components, and consumer products where plastic fastening reliability is critical.

Specification Summary & Compliance

These thread forming screws feature a 0.138" thread diameter with 19 threads per inch and full threading along the 5/16" length. The TRS (Thread Rolling Screw) design follows standard thread forming principles with Tri-Lobe shank geometry for plastic applications. Manufactured to precise dimensional standards with Class 2A thread tolerances. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring they meet current environmental and safety standards for industrial use.
