• Class 2A thread fit with UNC coarse threading delivers consistent engagement and vibration resistance in various materials
• Fully threaded shank maximizes grip length and load distribution across the entire fastener length
• RoHS 3 compliance guarantees environmental safety and regulatory acceptance for industrial applications
• 140°F temperature rating maintains structural integrity in moderate heat conditions common to plastic assembly applications
• Right-hand threading with standardized 1/4"-20 dimensions ensures compatibility with existing UNC threaded components and tooling

Professional Applications & Engineering Value

These PVC plastic hex head screws solve critical challenges in industrial applications where metal fasteners would corrode or conduct electricity. The gray PVC material provides excellent chemical resistance while maintaining dimensional stability, making these fully threaded screws ideal for electrical enclosures, plumbing systems, and outdoor equipment. The coarse UNC threading with Class 2A fit ensures reliable engagement in both plastic and softer materials, reducing stripping risks. The external hex drive design allows for high torque application without cam-out, while the right-hand thread direction maintains industry standard installation procedures. These features combine to create durable, non-conductive fastening solutions for industrial plastic assemblies requiring consistent performance up to 140°F.

Specification Summary & Compliance

This 1/4"-20 UNC hex head screw maintains precise Class 2A thread fit tolerances per Unified Thread Standard specifications. The coarse thread spacing and fully threaded design ensure optimal performance in various materials. Manufacturing complies with RoHS 3 (2015/863/EU) regulations, containing no restricted hazardous substances. The external hex drive configuration and right-hand threading follow industry-standard fastening protocols for reliable integration into existing assembly systems.
