S-90380A285 Length 1" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction, extending service life in humid or demanding industrial environments
• Exceptional holding power in plastic materials due to the Tri-Lobe shank design that displaces material without creating chips
• Reduced installation torque and stripping risk with precision thread forming technology that creates strong, clean threads in plastic
• Wide compatibility and easy installation with standard No. 2 Phillips drive and blunt tip for straightforward positioning
• Reliable performance in sensitive applications with full RoHS 3 and REACH compliance, meeting strict environmental regulations
• Optimized for plastic assembly efficiency with fully threaded 1" length and 20 TPI design for maximum engagement and pull-out resistance
• Secure fastening in vibration-prone applications with thread forming action that creates permanent, zero-backlash connections

Professional Applications & Engineering Value

Engineered specifically for plastic assembly applications, these TRS tapping screws solve critical challenges in modern manufacturing. The thread forming technology eliminates chip formation that can compromise electronic components or contaminate clean environments, while the Tri-Lobe shank cross-section provides up to 30% greater resistance to vibrational loosening compared to standard fasteners. The zinc-plated steel construction ensures durability in both indoor and protected outdoor applications, making these self-tapping screws ideal for automotive trim, electrical enclosures, consumer electronics, and industrial equipment where plastic-to-plastic or plastic-to-metal connections require reliable, long-term performance without the need for additional inserts or adhesives.

Specification Summary & Compliance

This No. 5 x 1" tapping screw features precision 0.125" thread diameter with 20 threads per inch and Class 2A thread tolerances for consistent performance. The TRS (Thread Rolling Screw) design follows industry-standard thread forming specifications with fully threaded construction and standard pan head profile. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring suitability for global markets and sensitive applications where material restrictions apply.
