Professional Applications & Engineering Value

These 8-32 UNC fillister head screws deliver exceptional engineering value in demanding industrial settings where corrosion resistance and mechanical integrity are paramount. The 18-8 stainless steel composition, enhanced by passivated finish, provides superior protection against oxidation and chemical exposure, making them ideal for marine equipment, food processing machinery, and outdoor applications. The high-profile rounded head design offers improved tool clearance while maintaining a low rotational profile, and the coarse UNC threading ensures rapid installation in various materials. With full threading along the 7/8" length, these screws distribute clamping force evenly, preventing joint failure in vibration-prone assemblies. The combination of 70,000 psi tensile strength and standardized dimensions makes them a reliable choice for OEM manufacturing and maintenance operations requiring consistent performance.

Specification Summary & Compliance

This fillister head screw features precise Class 2A thread fit with UNC coarse threading (8-32 size) and maintains dimensional accuracy per ASME B18.6.3 specifications. The manufacturing process ensures compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, confirming the absence of restricted substances. Thread diameter measures 0.164" with complete threading along the 7/8" length, providing reliable fastening performance across industrial applications.
