Professional Applications & Engineering Value

These zinc-plated steel screws with integrated split lock washers deliver critical vibration resistance in industrial assemblies where loosening under dynamic loads poses significant reliability concerns. The UNC coarse thread configuration combined with Class 2A thread fit ensures rapid installation and consistent clamping force in production environments. The Phillips pan head design provides a balanced combination of drive efficiency and low-profile installation, while the fully threaded construction maximizes engagement in various material thicknesses. Engineered for machinery, electrical enclosures, and automotive components, these 8-32 screws maintain integrity under continuous vibration and thermal cycling, reducing maintenance frequency and assembly failures.

Specification Summary & Compliance

This fastener features precision UNC coarse threads with Class 2A fit tolerance, ensuring consistent thread engagement and proper clearances. Manufacturing complies with ASME B18.13 specifications for dimensional accuracy and performance requirements. The product meets RoHS 3 (2015/863/EU) compliance for restricted substances and REACH (EC 1907/2006) regulations regarding chemical safety. With a defined thread diameter of 0.164" and length of 3/4", these screws maintain dimensional consistency across production batches for reliable interchangeability in industrial applications.
