Professional Applications & Engineering Value

This PEEK plastic socket head cap screw delivers exceptional engineering value in demanding environments where metal fasteners fail. The high-temperature resistance (-50°F to 500°F) makes it ideal for thermal management applications in aerospace, automotive, and electronics industries. The chemical-resistant properties of PEEK material prevent degradation from solvents, fuels, and cleaning agents, while the UL 94 V-0 rating provides critical fire safety in electrical enclosures and consumer electronics. The 2-56 UNC thread with Class 2A fit ensures reliable performance in vibration-prone assemblies, and the fully threaded design offers maximum engagement strength. These industrial plastic screws eliminate galvanic corrosion concerns in mixed-material assemblies while maintaining 25,000 psi tensile strength comparable to many metal alternatives.
