Professional Applications & Engineering Value
This nylon patch locking pan head Phillips screw delivers critical vibration resistance in industrial machinery, automotive assemblies, and electronic enclosures where loosening under dynamic loads poses significant reliability concerns. The 18-8 stainless steel material with passivated finish provides exceptional corrosion protection in humid or chemically aggressive environments, while the permanent nylon patch locking mechanism maintains clamp load without compromising reusability. The UNC coarse threads with Class 2A fit ensure rapid installation and consistent performance in production environments, making this fully threaded fastener ideal for applications requiring both security and corrosion resistance. The combination of 60,000 psi tensile strength and temperature-stable locking from -70° to 250°F addresses common failure modes in vibration-prone assemblies.
Specification Summary & Compliance
This fastener features 1/4"-20 UNC coarse threads with Class 2A dimensional accuracy and fully threaded 1-1/2" length. Manufacturing complies with ASME B18.6.3 mechanical and dimensional specifications. The product is certified RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, meeting current environmental regulations for industrial use.
