Professional Applications & Engineering Value
Engineered for demanding sectors, these PEEK plastic rounded head screws address critical challenges in aerospace, automotive, and electronics. The high-temperature resistance ensures stability in engine compartments or near heat sources, while the chemical inertness prevents degradation from oils, solvents, and fuels. With a coarse 4-40 UNC thread and Class 2A fit, they provide reliable clamping force in plastic or composite assemblies, reducing stress cracking. The Phillips drive and rounded pan head design facilitate quick installation in tight spaces, making them ideal for industrial fastening where weight, corrosion, and electrical insulation are priorities.
Specification Summary & Compliance
This screw adheres to ASME B18.6.3 specifications, with Class 2A thread fit ensuring dimensional accuracy for consistent performance. It features a 4-40 UNC coarse thread with right-hand direction and full threading for maximum engagement. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) confirms it is free of hazardous substances, supporting sustainable and safe manufacturing practices.
