Professional Applications & Engineering Value

This 3/8"-24 UNF fine thread socket head hex nut delivers exceptional performance in precision assembly applications where corrosion resistance and thread reliability are critical. The 18-8 stainless steel construction provides excellent durability against chemical exposure and atmospheric corrosion, while the Class 2B thread fit ensures consistent engagement with mating components. The partially threaded design allows for controlled clamping force distribution, making it ideal for machinery, automotive, and aerospace applications requiring precise torque management. The hex socket drive facilitates installation in tight spaces where conventional wrenches cannot access, and the fine thread spacing enhances vibration resistance in high-stress environments.

Specification Summary & Compliance

Manufactured to precise dimensional standards with 0.59" OD and 0.62" height, this socket nut features 3/8"-24 UNF fine threading with Class 2B thread fit tolerance for consistent performance. The product complies with REACH (EC 1907/2006) and RoHS 3 (2015/863/EU) environmental regulations, ensuring safe use across industrial sectors. Designed for 0.61" hole diameter applications with 0.33" thread depth, this fastener meets industry standards for precision thread nuts in demanding mechanical assemblies.
