Metallics N1651M – Frequently Asked Questions
1) Is the N1651M nut strong enough for threaded rod hanging pipe or fixtures?
It is a Grade 2 steel nut with a hardness of Rockwell B68 to C32. Grade 2 is the standard commercial strength for general electrical, plumbing and HVAC hanger work. If your drawing calls out Grade 5 or Grade 8 nuts for a structural or high-load connection, specify those instead.
2) How many nuts come in a box of Metallics N1651M, and can I buy a smaller quantity?
These ship as a box of 1,000 nuts, and 1,000 is the order minimum, so that is the smallest pack. Metallics does offer other sizes and quantities by request if you need a different count or thread size.
3) Can zinc plated hex nuts like the N1651M be used outdoors or in damp locations?
The N1651M carries a zinc finish over steel, which handles indoor and normally dry or occasionally damp conditions. Zinc plating is not a marine or continuously wet finish, so for exterior exposure, roof-mounted equipment, pool rooms or wash-down areas, go with stainless or hot dip galvanized hardware instead.
4) Do these Metallics hex nuts meet Buy American and ARRA requirements for a public project?
The N1651M is flagged compliant for both Buy American and ARRA in the manufacturer's data. Country of origin is listed as multiple, so if your contract requires documented origin per shipment, request the certification with the order.
5) How much does a box of 1000 Metallics 3/8-16 hex nuts weigh and how big is the carton?
The box weighs 15.02 lbs and measures 7.25 in long, 6.75 in wide and 3.25 in high. Easy enough for one person to carry to a van or a job gang box.
6) What trades use the Metallics N1651M 3/8-16 hex nut?
Metallics lists it for the electrical, plumbing, heating and air conditioning industries. In practice that means securing 3/8-16 threaded rod for conduit and cable tray hangers, strut assemblies, pipe hangers and unit heater or fan coil supports. Stocking a box of 1,000 covers most of a building's rod work in one line item.
