Professional Applications & Engineering Value
This nylon plastic socket head cap screw with 4-40 UNC coarse threading delivers critical engineering advantages where metal fasteners fail. The electrical insulation properties make it ideal for electronic enclosures, circuit boards, and electrical components where current isolation is mandatory. The inherent corrosion resistance ensures long-term reliability in chemical processing, marine environments, and washdown applications without galvanic corrosion concerns. The Class 2A thread fit with right-hand direction provides consistent engagement in plastics, composites, and soft materials while the fully threaded design offers maximum holding power across the entire 1-1/8" length. These characteristics solve common industrial pain points including weight reduction, chemical compatibility, and electrical safety requirements.
Specification Summary & Compliance
Manufactured to UNC thread standards with precise Class 2A thread fit tolerance for consistent performance. The screw features coarse thread spacing with right-hand thread direction and fully threaded rod type. Compliant with RoHS 3 (2015/863/EU) regulations restricting hazardous substances. The inch system measurement ensures compatibility with North American equipment and specifications while the standard socket head profile with 3/32" hex drive maintains tooling consistency across fastener systems.
