Metallics HHN58CCL – Frequently Asked Questions
1) What thread size does the Metallics HHN58CCL heavy hex nut take?
It's a 5/8-11 nut, so it threads onto 5/8 inch rod or bolt with 11 threads per inch, the standard UNC coarse pitch at that diameter. If your rod is 5/8-18 fine thread, this is the wrong nut.
2) Will a heavy hex nut work on 5/8 inch threaded rod for hanging unistrut and conduit trapeze?
Yes, on 5/8-11 rod. A heavy hex nut has a larger across-flats and a thicker body than a standard hex nut of the same thread, so it gives more bearing area against the strut or fitting and more thread engagement for overhead support work. Use it with a flat washer where it bears on channel or sheet steel.
3) Is the HHN58CCL nut plated, and is it OK outdoors or in damp locations?
The nut is steel with a zinc finish. Zinc plating handles dry interior and normally dry service fine, but it's a sacrificial coating, not stainless, so for wet exterior, coastal, or corrosive environments you want hot dip galvanized or stainless hardware instead.
4) How many nuts come in a box of Metallics HHN58CCL?
250 pieces per box. It's a bulk pack for electrical and MRO crews doing repeat trapeze, strut, and anchor-rod work, not a count-out quantity, so plan the order around a full box.
5) What is the difference between a heavy hex nut and a regular hex nut in 5/8-11?
Same thread, different body. Both take 5/8-11 thread, but the heavy hex pattern is wider across the flats and taller, so it needs a bigger wrench and spreads load over more surface. Contractors reach for heavy hex on structural connections and heavier anchor rod; a standard hex nut is the usual choice for lighter general fastening where clearance is tight.
6) What is the Metallics part number for the 5/8-11 heavy hex zinc nut?
HHN58CCL is the Metallics catalog number for the 5/8-11 heavy hex steel zinc nut in the 250 piece box. That's the number to quote for a reorder.
