Professional Applications & Engineering Value

This nylon socket head cap screw delivers critical engineering advantages where metal fasteners fail. The Nylon Plastic construction provides inherent corrosion resistance, making it ideal for chemical processing, marine, and outdoor applications where moisture and corrosive agents are present. Its non-conductive properties prevent electrical shorts in electronic enclosures, control panels, and electrical assemblies. The UNC coarse threads with Class 2A fit ensure rapid installation and reliable performance in plastic and soft materials, while the hex socket drive allows for high torque application without cam-out. Operating across a -40° to 140° F temperature range, this fastener maintains dimensional stability in various industrial environments where thermal expansion concerns exist with metal alternatives.

Specification Summary & Compliance

This 1/4"-20 UNC socket head cap screw features Class 2A thread fit per standard inch series specifications, ensuring proper clearance and engagement. The fastener is fully threaded with right-hand direction and manufactured to meet RoHS 3 (2015/863/EU) compliance requirements. The coarse thread spacing provides excellent holding power in various materials while the standardized hex drive size of 3/16" ensures compatibility with common installation tools.
