Professional Applications & Engineering Value

Engineered for demanding industrial applications, this glass-filled nylon socket head cap screw delivers exceptional performance where metal fasteners fail. The 10-24 UNC coarse thread with Class 2A fit provides reliable engagement in plastic and soft material assemblies, while the right-hand thread direction ensures standard installation compatibility. The material's inherent chemical resistance makes it ideal for chemical processing, food equipment, and electrical enclosures where corrosion resistance is critical. With operating temperatures from -20° to 230°F, this fastener maintains dimensional stability in thermal cycling environments, preventing loosening and maintaining clamp force. The 5/32" hex drive socket head configuration allows for high-torque installation in space-constrained applications, making it perfect for machinery, automotive components, and electronic assemblies requiring non-conductive, non-magnetic fastening solutions.

Specification Summary & Compliance

This socket head cap screw features precision 10-24 UNC coarse threads with Class 2A thread fit per ASME B1.1 standards, ensuring consistent dimensional accuracy and reliable performance. The 3/8" length and fully threaded design provide maximum fastening flexibility. Manufacturing complies with UL 94 HB flammability requirements, RoHS 3 (2015/863/EU) for hazardous substance restriction, and REACH (EC 1907/2006) regulations for chemical safety, making it suitable for global industrial applications and environmentally conscious manufacturing processes.
