Professional Applications & Engineering Value
This 1/4"-28 UNF socket head cap nut delivers exceptional performance in demanding applications where space constraints and corrosion resistance are critical. The 18-8 stainless steel construction provides excellent durability against oxidation and chemical exposure, making it ideal for machinery, automotive assemblies, and marine equipment. The fine UNF threading with Class 2B fit ensures precise engagement with mating components, reducing the risk of cross-threading while maintaining vibration resistance in high-stress environments. The partially threaded design concentrates clamping force where needed most, preventing joint loosening while the hex socket drive enables installation in tight spaces where conventional wrenches cannot access.
Specification Summary & Compliance
This socket nut features precision 1/4"-28 UNF fine threading with Class 2B thread fit tolerances, ensuring consistent performance across industrial applications. Manufactured to exacting standards with 0.421" hole diameter compatibility and 0.23" thread depth for secure fastening. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, meeting the latest environmental and safety standards for industrial components.
