Professional Applications & Engineering Value
Engineered for demanding industrial environments, these nylon plastic socket head cap screws deliver critical performance advantages where metal fasteners fail. The 4-40 UNC coarse thread configuration ensures rapid installation and reliable holding power in plastic assemblies, electronic enclosures, and corrosion-prone applications. Unlike metallic alternatives, these fully threaded fasteners provide complete electrical insulation while resisting chemicals, moisture, and galvanic corrosion. The right-hand thread direction with Class 2A fit maintains precise tolerances for vibration-resistant connections in machinery, automotive components, and electrical systems operating within the -40° to 140°F temperature spectrum.
Specification Summary & Compliance
This socket head cap screw features 4-40 UNC coarse threads with Class 2A thread fit per ASME B1.1 standards, ensuring dimensional accuracy and interchangeability. The 9/16" length and 0.183" head diameter provide consistent sizing within the inch measurement system. Manufacturing complies with RoHS 3 (2015/863/EU) regulations, containing no restricted hazardous substances. The 3/32" hex drive socket maintains compatibility with standard industrial tools for efficient installation and maintenance procedures.
