Professional Applications & Engineering Value
This polypropylene socket head cap screw addresses critical challenges in electrical enclosures, food processing equipment, and chemical handling systems where metal fasteners would corrode or contaminate products. The 6-32 UNC coarse thread configuration prevents stripping in plastic housings while the standard socket head profile accommodates high-torque installation. Engineers specify this ASME B18.3 compliant fastener for applications requiring non-conductive, non-magnetic properties combined with 4500 psi tensile strength. The right-hand thread direction and Class 2A fit ensure compatibility with existing industrial equipment while the off-white color blends discreetly into manufactured products.
Specification Summary & Compliance
Manufactured to ASME B18.3 specifications with Class 2A thread fit tolerance for consistent performance. Features 6-32 UNC coarse threads with right-hand direction and fully threaded design. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. The 1-1/2" length and 0.226" head diameter maintain dimensional accuracy per industrial standards.
