- Off-white color and plastic composition offers excellent visibility and electrical insulation properties
Professional Applications & Engineering Value
Engineered for precision assembly where metal fasteners pose contamination or corrosion risks, these polypropylene socket head cap screws deliver exceptional performance in electrical enclosures, food processing equipment, and laboratory instrumentation. The 6-32 UNC coarse thread configuration provides superior engagement in plastic housings and soft materials, while the standard socket head profile allows high torque application without stripping. Their temperature resistance makes them ideal for applications experiencing thermal cycling, and the non-conductive properties prevent electrical shorts in sensitive electronic assemblies. These fasteners solve critical challenges in industries requiring lightweight, corrosion-proof fastening solutions that meet stringent regulatory requirements.
Specification Summary & Compliance
Manufactured to inch system specifications with precise Class 2A thread fit per UNC standards. Features fully threaded 1/4" length with right-hand coarse threading and standard socket head profile. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring suitability for global industrial applications requiring hazardous substance restrictions.
