Professional Applications & Engineering Value
This 2-56 UNC nylon plastic hex head screw is engineered to address common challenges in lightweight assembly and corrosive environments. The black nylon material offers inherent resistance to moisture, chemicals, and UV exposure, preventing degradation and ensuring long-term reliability in electrical enclosures, automotive trim, and consumer appliances. The coarse thread and Class 2A fit minimize cross-threading risks and provide excellent pull-out strength in thermoplastic housings and composite materials. Its external hex drive facilitates quick, tool-compatible installation, reducing assembly time while maintaining a secure, non-conductive, and lightweight fastening solution that meets stringent industry standards.
Specification Summary & Compliance
This screw adheres to the Unified National Coarse (UNC) 2-56 thread standard with a Class 2A thread fit for consistent dimensional accuracy. Manufactured in the inch system, it features a 3/16" length, 1/8" head width, and is fully threaded. The product is fully RoHS 3 (2015/863/EU) Compliant, ensuring it is free from hazardous substances for safe use in various industrial and electronic applications.
