Professional Applications & Engineering Value
This nylon plastic socket head cap screw is engineered to address critical challenges in industries requiring non-conductive, corrosion-resistant fastening solutions. Its 4-40 UNC coarse threads with Class 2A fit provide reliable engagement in plastic, composite, or metal assemblies, preventing galvanic corrosion and electrical shorts. The fully threaded design ensures maximum holding power across the entire length, while the standard socket head profile with 3/32" hex drive facilitates efficient installation in confined spaces. Ideal for electrical enclosures, instrumentation, and consumer electronics, this screw maintains integrity across a -40° to 140°F temperature range, offering a durable alternative to metal fasteners in sensitive applications.
Specification Summary & Compliance
This screw adheres to UNC coarse thread standards with Class 2A thread fit for consistent dimensional accuracy. Manufactured from nylon plastic with a right-hand thread direction and fully threaded rod type, it meets RoHS 3 (2015/863/EU) compliance for environmental safety. Key dimensions include a 1/8" length, 0.183" head diameter, and 0.112" head height, ensuring compatibility with standard inch-system components.
