Metallics JWNCF4 Nuts 10-24 Wing Nut Forge-St (Jar 100)

The JWNCF4 is a 10-24 wing nut, so it threads onto a #10 machine screw or bolt with 24 threads per inch. It is made to ANSI/ASME B18.17, which is the wing nut dimensional standard, so it will mate with any standard 10-24 male thread.

Plan on roughly an inch of free space around the stud. The wings on the JWNCF4 spread 0.78 to 0.91 inches tip to tip, stand 0.34 to 0.47 inches tall, and are 0.10 to 0.14 inches thick, with a base diameter of 0.39 to 0.43 inches. In a tight box or behind a crowded panel, that wing spread is what decides whether you can finger tighten it or need a hex nut and a wrench instead.

The JWNCF4 is flagged as both Buy American compliant and ARRA compliant in the manufacturer's data, which is what a government, school, or healthcare procurement file usually needs on a fastener line item. Country of origin is listed as multiple, so if your specification requires a single named origin, confirm the origin on the lot you receive.

It is cold forged steel with a zinc finish, which gives it basic corrosion resistance for normal indoor and protected electrical work. Zinc plated steel is not a marine or constantly wet duty finish, so for direct weather exposure or washdown areas use a stainless wing nut instead.

A wing nut is for fastenings you expect to open again without tools, such as cover plates, ground straps, battery or terminal connections, and temporary mounting. The JWNCF4 tightens by hand on a 10-24 thread. Where the joint needs a controlled torque or has to resist vibration loosening, a hex nut with a lock washer is the better choice.

It ships 100 nuts in a jar, and 100 count is the order minimum. Total shipping weight for the jar is 0.75 lbs, with the container measuring 3 x 3 x 2.15 inches, so it stores easily on a van shelf or in a bin.

Yes. The JWN series of cold forged steel wing nuts runs in other thread sizes and other pack quantities by request; the JWNCF4 is the 10-24 version in a 100 count jar. If you are standardizing a facility on one hand-tightened fastener, specify the thread size you need when you order.

Forged steel is the body material here, not folded sheet. That matters on the wings: a forged wing at 0.10 to 0.14 inches thick resists bending when someone cranks it down by hand, where a thin stamped wing can deform and become hard to grip. For repeated open-and-close service, forged is the one to spec.
