These ASMC Industrial 1/4"-20 hex nuts feature standard coarse threading that fits 1/4-inch diameter bolts with 20 threads per inch, making them compatible with common fasteners in machinery, vehicles, and construction. The coarse thread design allows efficient assembly with a strong grip in softer materials like aluminum and wood, while the wider spacing bites securely into aluminum taps and plastic inserts. Each nut is made from low-carbon steel with protective zinc plating that prevents corrosion in workshops, garages, and light outdoor applications, keeping assemblies secure without rust stains. The finished hex surface ensures smooth threading without cross-threading, requiring only a standard 7/16-inch wrench or socket for installation. These lock nuts won't crack under normal tightening yet remain strong for load-bearing applications in hardware assemblies, with lot control ensuring consistent dimensions. From mechanics working on suspension mounts to electricians securing conduit brackets and builders fastening deck railings, these versatile fastener hardware pieces appear across countless industries. This bulk pack provides enough inventory for contractors, DIYers, or manufacturers without excessive warehouse storage in a nut and bolt organizer. These 1/4"-20 nuts work with any standard flat washer or split lock washer you stock, with consistent dimensions ensuring compatibility for secure, vibration-resistant assemblies in your nuts and bolts kit or hardware assortment kit collection.
