Professional Applications & Engineering Value
This fiberglass hex nut delivers exceptional value in demanding environments where metal fasteners fail. The non-conductive, corrosion-resistant material eliminates galvanic corrosion risks when mating with dissimilar metals, while maintaining structural integrity under thermal stress up to 190°F. Engineered with UNC coarse threads and Class 2B thread fit, it resists vibration loosening in machinery, electrical enclosures, and chemical processing equipment. The gray standard profile provides visual consistency in assembled products, and the external hex drive ensures compatibility with standard maintenance tools. Ideal for industrial applications requiring durable, non-metallic fastening solutions that won't compromise electrical insulation or contaminate sensitive environments.
Specification Summary & Compliance
This 1/4"-28 UNC hex nut features Class 2B thread fit per ASME B1.1 standards with coarse thread spacing for reliable engagement. Manufacturing complies with RoHS 3 (2015/863/EU) environmental directives, containing no restricted hazardous substances. Dimensional specifications include 7/16" width across flats and 7/32" height, maintaining consistent inch system tolerances for industrial compatibility.
