Professional Applications & Engineering Value

This PEEK plastic socket head cap screw is engineered to solve critical challenges in industries where high-temperature stability, chemical resistance, and non-conductivity are paramount. Its PEEK material maintains structural integrity from -50° to 500° F, preventing deformation or failure in thermal processing, aerospace, and automotive applications. The 8-32 UNC coarse thread and Class 2A fit provide reliable engagement in plastic or soft metal components, reducing installation time and improving joint consistency. The socket head design with a 9/64" hex drive offers a secure tool interface for confined spaces, ensuring precise torque control. Ideal for electrical enclosures, semiconductor equipment, and medical devices, this fastener delivers long-term performance where metal screws would corrode, gall, or cause galvanic issues.

Specification Summary & Compliance

This socket head cap screw adheres to ASME B18.3 specifications for dimensional consistency. The 8-32 UNC thread features a Class 2A tolerance for precise fit and coarse thread spacing for robust engagement. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming the absence of restricted hazardous substances. The UL 94 V-0 rating validates its flame-retardant properties, making it suitable for safety-critical applications.
