Metallics JHHN1 Nuts 1-8 Hvy Hx Nut St-zn (Jar 100)

The JHHN1 is a 1-8 heavy hex nut: 1 inch nominal diameter at 8 threads per inch, which is the standard UNC coarse pitch for 1 inch rod and bolts. It will thread onto 1 inch all-thread rod or 1-8 bolts; it will not fit 1-12 or 1-14 fine thread.

Heavy pattern. A heavy hex nut has a larger across-the-flats dimension and greater thickness than a finished hex nut of the same thread, so it needs a bigger wrench and bears on more surface area. If your drawing calls out a finished hex nut and clearance around the fastener is tight, the heavy pattern may not fit the pocket.

The zinc plating on these steel nuts gives moderate corrosion resistance, which suits indoor, dry, and sheltered mechanical spaces. For sustained outdoor exposure, wet locations, or coastal air, step up to hot dip galvanized or stainless hardware, and keep the plating consistent with the rod so you are not mixing zinc plated nuts onto galvanized rod.

Yes, the order minimum is 25 count. Other sizes and quantities of Metallics JHHN series heavy hex nuts can be supplied by request if 1-8 is not the size you need.

The JHHN1 carries both ARRA and Buy American compliance flags in its product record, with country of origin listed as China. On a federally funded job, check which clause your contract actually invokes, because a domestic sourcing requirement and an ARRA compliance designation are not the same test.

They ship 100 nuts to a jar. The jar packaging is useful on a cart or gang box because it keeps a count of 1 inch nuts together instead of loose in a bin.

4.45 lbs per jar, with the container measuring 7.25 by 4.5 by 4.5 inches. Worth knowing if you are stocking a service van or figuring hanger kit weights for a bulk pull.
