Metallics JSQ8SS – Frequently Asked Questions
1) What thread does the Metallics JSQ8SS square nut take?
It's a 3/8 inch right-hand UNC thread at 16 threads per inch, so it runs onto standard 3/8-16 coarse-thread bolts, rod, and strut hardware. Left-hand thread and fine (UNF) 3/8-24 fasteners will not engage it.
2) What wrench size fits a 3/8-16 stainless square nut?
Across the flats the nut measures 0.607 to 0.625 inch, and on this part the width across flats is the wrench size, so a 5/8 inch wrench or socket is the one to grab. Height is 0.239 to 0.257 inch.
3) Will stainless square nuts hold up outdoors or in a wet location?
The JSQ8SS is 18-8 stainless steel, which is the standard austenitic grade for damp, outdoor, and washdown work where plated steel would rust and seize. For a conduit run on a roof, a parking structure, or a pool mechanical room, that's the right material choice. In chloride-heavy coastal or pool-chemical exposure, 316 is the step up.
4) Do these stainless square nuts meet Buy American and ARRA requirements for a federal job?
Metallics lists the JSQ8SS as compliant for both Buy American and ARRA, which is what a government or institutional procurement file usually needs on the fastener line. Country of origin is listed as multiple.
5) Why use a square nut instead of a hex nut on a strut or channel job?
Square nuts give you four flats and more bearing surface, and the flat sides will wedge against a channel wall or a slot so the nut holds itself while you turn the bolt from one side. The JSQ series is made for use with square bolts and to American Standard dimensions. If you're torquing in open air with a socket on both ends, a hex nut is easier.
6) How many 3/8-16 stainless square nuts come in a jar?
They ship 100 to a jar, and 100 count is the order minimum. The jar runs 0.92 lbs. Metallics does other sizes and quantities on request.
7) Is the JSQ8SS the plain stainless nut or a plated steel one?
Stainless, not plated. The JSQ square nut line is offered in steel-zinc as well as 18-8 stainless, and the SS suffix on JSQ8SS is the 18-8 stainless version. If you're matching existing zinc-plated hardware on an interior dry run, ask for the steel-zinc JSQ in the same 3/8-16 size.
8) How hard is the JSQ8SS square nut, and will it strip on a stainless bolt?
Hardness runs Rockwell B68 to C32. Stainless on stainless does have a galling tendency as you approach that range, so run the nut on slowly and use an anti-seize on the thread rather than driving it fast with an impact.
