Professional Applications & Engineering Value
These 3/8"-16 UNC nylon hex head screws deliver exceptional value in industries where corrosion resistance and electrical insulation are critical. Made from durable nylon plastic, they eliminate galvanic corrosion risks in metal assemblies and provide non-conductive fastening for electrical enclosures, control panels, and marine equipment. The coarse thread design ensures quick installation and reliable holding power in plastic, wood, or soft metals, while the external hex drive facilitates high-torque application without stripping. Ideal for HVAC systems, automotive components, and outdoor fixtures, these screws operate reliably across a broad temperature range, solving common issues like thermal expansion and environmental degradation.
Specification Summary & Compliance
This screw features a 3/8"-16 UNC coarse thread with Class 2A thread fit for consistent dimensional accuracy and easy assembly. It is manufactured in accordance with inch system standards, offering a length of 1-1/4" and partial threading for versatile use. The product is fully RoHS 3 (2015/863/EU) compliant, ensuring it meets strict environmental regulations for hazardous substance restrictions.
