Value Collection 34292 Serrated Flange Nut 1/4-20 Zinc Steel

Product Description

The VALUE COLLECTION 34292 is a Grade 2 steel serrated flange nut with a 1/4-20 UNC thread and a zinc-plated finish. The integrated flange features machined serrations on its bearing face that bite into the mating surface during torquing, creating resistance to vibration-induced loosening without a separate lock washer. The flange diameter measures 0.594 inches and the overall height reaches 0.236 inches. This fastener is suited for light-to-medium duty mechanical assembly work across HVAC, electrical, plumbing, and general trade applications where a self-locking nut is required at the 1/4-20 thread size.

This nut sees common use in equipment panel assembly, sheet metal enclosures, mounting brackets, and mechanical sub-assemblies where vibration resistance is needed and a flat bearing surface is available. The serrated flange distributes clamp load across a wider area than a standard hex nut, reducing the chance of surface deformation on thinner materials. It is a standard inch-system fastener appropriate for residential and light commercial trade work.

Key Features

• Serrated flange bearing face locks against loosening under vibration without a separate washer
• 1/4-20 UNC thread for broad compatibility with standard inch-system hardware
• Grade 2 steel construction suitable for light-to-medium duty clamping loads
• Zinc-plated finish provides basic corrosion resistance in dry or mildly humid environments
• Flange diameter of 0.594 inches distributes load over a wider bearing area than a standard hex nut
• Width across flats ranges from 0.428 to 0.438 inches for use with standard 7/16-inch wrenching tooling

Compatibility

Designed as a standard replacement or new-installation serrated flange nut for any inch-system assembly using 1/4-20 UNC threaded fasteners and requiring a self-locking, load-distributing nut.

Installation Notes

Installation is performed by hand-threading onto a 1/4-20 bolt or stud, then torquing with a 7/16-inch wrench or socket until the serrated flange seats fully against the mating surface. Power down or de-energize any equipment before performing fastener work on electrical enclosures or mechanical assemblies. The serrations are single-use; once the nut has been torqued and removed, re-use is not recommended as the serration engagement may be reduced.
