Professional Applications & Engineering Value
These PVC hex head screws solve critical challenges in electrical enclosures, plumbing systems, and chemical processing equipment where metal fasteners would corrode or cause galvanic reactions. The gray PVC material provides excellent dielectric properties while resisting acids, alkalis, and moisture degradation. With UNC coarse threads and Class 2A fit, these screws maintain secure fastening in plastic substrates where fine threads might strip. The external hex drive ensures maximum torque transmission without cam-out issues common with Phillips drives. Ideal for HVAC components, water treatment systems, and food processing equipment requiring non-conductive, corrosion-resistant fasteners that meet stringent RoHS compliance standards.
Specification Summary & Compliance
Manufactured to precise dimensional standards with Class 2A thread fit and UNC thread form ensuring interchangeability with standard components. The 5/16"-18 thread size with coarse spacing provides optimal engagement in plastic and soft materials. Fully compliant with RoHS 3 (2015/863/EU) regulations, containing no restricted hazardous substances. The 2" length with 1" minimum thread length offers versatility across various material thicknesses while maintaining structural reliability up to 140°F operating temperatures.
