Professional Applications & Engineering Value

This PEEK plastic hex nut delivers critical performance advantages in demanding environments where metal fasteners fail. The high-temperature resistance up to 550°F makes it ideal for aerospace, automotive, and chemical processing equipment exposed to thermal cycling. Its black PEEK material provides excellent dielectric properties for electrical insulation applications while resisting degradation from fuels, solvents, and steam. The 1/2"-13 UNC coarse thread configuration ensures reliable performance in high-vibration settings, maintaining clamp load where fine threads might loosen. Engineers specify this industrial plastic nut for weight reduction initiatives without sacrificing the mechanical strength required for structural assemblies.

Specification Summary & Compliance

This hex nut features 1/2"-13 UNC coarse threads with Class 2B thread fit per ASME B1.1 standards, ensuring dimensional accuracy and interchangeability. Critical dimensions include 45/64" width across flats and 1/4" height for standardized tool engagement. The component is manufactured from premium PEEK plastic and complies with REACH (EC 1907/2006) and RoHS 3 (2015/863/EU) environmental directives, confirming absence of restricted substances for global industrial applications.
