• Precise Class 2A thread fit ensures smooth assembly and consistent clamping force in your components
• Phillips drive with standard pan head design provides secure tool engagement and a low-profile, rounded finish
• Full threading along the 3/8" length offers maximum grip and holding power across the entire fastener
• Compliance with ASME B18.6.3 guarantees dimensional accuracy and interchangeability in professional assemblies
• RoHS 3 and REACH compliance ensures environmental safety and regulatory acceptance for global markets

Professional Applications & Engineering Value

Engineered for demanding conditions, these PEEK plastic screws solve critical challenges in high-temperature and chemically aggressive environments. The 1/4"-20 UNC coarse thread and Class 2A fit provide reliable fastening in plastics, composites, and metal assemblies where thermal expansion or electrical insulation is a concern. The rounded pan head with Phillips drive facilitates easy installation while maintaining a smooth surface profile, reducing snag risks in machinery and enclosures. Ideal for industrial plastic fasteners in aerospace, automotive, and electronics, they offer a lightweight, non-conductive alternative to metal without sacrificing mechanical integrity.

Specification Summary & Compliance

This screw adheres to ASME B18.6.3 specifications, with a 1/4"-20 UNC coarse thread and Class 2A thread fit for precise dimensional tolerance. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring no restricted substances are present. The 0.49" head diameter and 3/8" length provide consistent sizing for repeatable assembly processes.
