Hex Machine Screw Nut · #10-24 UNC - Zinc Plated - H. Paulin 10-24HN
SKU: S-10-24HN
Zinc-plated hex machine screw nut for #10-24 UNC machine screws in electrical panels, boxes, brackets, and general fastening. Carbon steel construction with a bright zinc finish helps resist corrosion in typical indoor service.
What this product is for
This hex machine screw nut is used to secure #10-24 machine screws in electrical and general fastening work. It is commonly selected for panel hardware, equipment covers, brackets, and assemblies where a standard hex nut is required.
Use for
Use for #10-24 UNC machine screw assemblies, electrical enclosures, control panels, mounting brackets, and light mechanical fastening. It is commonly paired with matching zinc-plated screws and washers for consistent fit and finish.
Avoid for
Avoid for stainless-to-stainless matching requirements, highly corrosive environments, and applications that require a specified structural grade, locking feature, or certified vibration resistance. Do not use where a prevailing torque nut, locknut, or specialty fastener is required by design.
Best for
Best for electricians, panel builders, and maintenance teams needing a standard #10-24 hex nut for indoor electrical and mechanical assemblies. A practical choice when replacing missing hardware or building up small equipment and enclosure connections.
Installed in
Typically installed in electrical panels, junction boxes, device brackets, control cabinets, equipment housings, and other assemblies using #10-24 machine screws. Size is a key buying factor here, so confirm thread match before ordering.
Why this product exists
This product provides a simple threaded fastening point for #10-24 machine screws where tapped holes are not used. The hex shape allows standard wrench tightening, and the bright zinc-plated carbon steel construction is commonly used for general indoor service.
Compared with similar products
Compared with stainless steel machine screw nuts, this zinc-plated carbon steel version is typically chosen for lower-cost indoor applications. Compared with locknuts, it does not provide a built-in locking feature, so a lock washer or other retention method may be used where vibration is a concern. Typical trade guidance only: actual performance depends on installation conditions, load, vibration, and local electrical code.
