Professional Applications & Engineering Value
These PEEK plastic socket head cap screws deliver exceptional value in applications where metal fasteners fail. The beige PEEK material maintains structural integrity across extreme temperature cycles from -50° to 500°F while providing inherent chemical resistance to harsh industrial environments. The 8-32 UNC coarse thread configuration with Class 2A fit ensures rapid assembly with consistent clamping force, while the standard socket head profile accommodates common 9/64" hex tools for efficient maintenance. Ideal for semiconductor equipment, medical devices, aerospace components, and chemical processing systems, these fasteners eliminate galvanic corrosion concerns while meeting stringent industry standards for performance and safety.
Specification Summary & Compliance
Manufactured to precise dimensional requirements with Class 2A thread fit per UNC standards and ASME B18.3 specifications. These 1-1/2" fully threaded screws feature right-hand coarse threads with 0.164" diameter and standard socket head profile. Full compliance with RoHS 3 (2015/863/EU), REACH (EC 1907/2006) regulations, and UL 94 V-0 flammability rating ensures suitability for regulated industries and international markets.
