Metallics JWNCF7 – Frequently Asked Questions
1) Is this wing nut strong enough for electrical strut and hanger work, or is it just a light-duty stamped nut?
It is cold forged steel, not a thin stamped nut, so the wings hold up to repeated hand tightening on strut, hanger rod, and ground strap work. The zinc finish gives it corrosion resistance for normal indoor and protected electrical installations.
2) How big are the wings on a 5/16-18 wing nut like the JWNCF7? I need to know if a hand can get to it in a tight box.
Wing spread runs 1.12 to 1.25 inches, wing height 0.53 to 0.66 inches, and wing thickness 0.17 to 0.21 inches. Base diameter is 0.51 to 0.58 inches. That gives you roughly an inch and a quarter of grip across, so finger tightening works in a reasonably open space, but figure on at least about 1-1/4 inches of clearance around the fastener for a hand to turn it.
3) How does the JWNCF7 wing nut ship, and what is the minimum I can buy?
It ships as a jar of 100 pieces, and 100 count is the order minimum, so the jar is the smallest unit. Jar weight is 1.84 lbs. Other sizes and quantities can be had by request.
4) Do Metallics JWN wing nuts meet Buy American and ARRA requirements for a federal or public job?
The JWNCF7 is flagged compliant for both Buy American and ARRA. Country of origin is listed as multiple, so if your specification requires documentation of a single origin country for a given lot, request it against the shipment.
5) When should I use a wing nut instead of a standard hex nut on an electrical install?
Use a wing nut where the connection gets taken apart again by hand: temporary bonding jumpers, panel covers, access plates, lighting fixture mounts, and ground straps you expect to service. No wrench or socket is needed. For a permanent structural connection, or anywhere you need a specified torque value or a locking feature, stay with a hex nut and lock washer. The JWNCF7 covers the 5/16-18 size in that service.
6) Is the JWNCF7 the same part number regardless of finish or size option?
JWNCF7 is a single part: the 5/16-18 cold forged steel wing nut in zinc, jar of 100. There is one model under that number, so ordering JWNCF7 gets you that exact configuration with no finish or size to select.
