Professional Applications & Engineering Value
This 1/4"-20 UNC left hand thread hex nut delivers critical engineering solutions where standard right-hand threads would loosen under reverse rotational forces. Manufactured from 316 Stainless Steel, it provides superior corrosion resistance in marine, chemical processing, and outdoor industrial settings. The coarse thread spacing combined with Class 2B thread fit ensures rapid installation and maintains clamping force in high-vibration environments like rotating machinery, conveyor systems, and automotive assemblies. The external hex drive profile offers maximum tool accessibility for maintenance operations. These industrial hex nuts are engineered to prevent accidental disassembly in left-hand thread applications while withstanding extreme operational stresses.
Specification Summary & Compliance
This hex nut features 1/4"-20 UNC left-hand threads with Class 2B thread fit and coarse spacing. Dimensions include 7/16" width across flats and 7/32" height. Manufactured to inch measurement standards with standard hex profile and external drive style. The product is RoHS 3 (2015/863/EU) compliant and meets industry specifications for 316 Stainless Steel fasteners.
