Professional Applications & Engineering Value

This 6061 aluminum thin hex nut delivers optimal performance where weight reduction and corrosion resistance are critical engineering considerations. The UNC coarse thread configuration with Class 2B fit provides reliable engagement in vibration-prone applications while allowing for quicker assembly compared to fine-thread alternatives. The thin profile makes it ideal for space-constrained assemblies in electronics enclosures, machinery guards, and lightweight structural frameworks. Manufactured to ASME B18.2.2 specifications, this hex nut ensures dimensional consistency across production runs and compatibility with standard 1/4"-20 threaded components. The external hex drive accommodates standard wrenching tools, facilitating efficient installation and maintenance in industrial settings where accessibility may be limited.

Specification Summary & Compliance

This thin hex nut features precise Class 2B thread fit with 1/4"-20 UNC coarse thread spacing and right-hand thread direction. Dimensions include 7/16" width across flats and 5/32" height, conforming to ASME B18.2.2 standards for dimensional accuracy. The product is manufactured from 6061 aluminum and complies with RoHS 3 (2015/863/EU) with exemption 6(b)-II for lead as an alloying element in aluminum, along with REACH (EC 1907/2006) compliance regarding Substances of Very High Concern.
