Professional Applications & Engineering Value
These gray PVC hex head screws solve critical challenges in industrial applications where metal fasteners would corrode or contaminate sensitive environments. The PVC plastic material provides excellent chemical resistance while maintaining sufficient mechanical strength for light to medium-duty fastening. The external hex drive combined with coarse UNC threading ensures quick installation and reliable holding power in plastic assemblies, electrical enclosures, and fluid handling systems. Engineers value these fully threaded screws for their consistent performance in applications requiring non-conductive, non-magnetic properties while the Class 2A thread fit guarantees precise engagement without cross-threading issues common in plastic components.
Specification Summary & Compliance
Manufactured to precise dimensional standards with Class 2A thread fit tolerance for consistent performance. Features UNC 5/16"-18 coarse threads with right-hand orientation and full threading along the 1" length. Head dimensions standardized at 17/64" height and 1/2" width for tool compatibility. Compliant with RoHS 3 (2015/863/EU) environmental regulations, ensuring safe use in various industrial applications without hazardous substance concerns.
