Metallics N1635M – Frequently Asked Questions
1) Will a Metallics N1635M hex nut thread onto 1/4-20 bolts and rod?
Yes. The N1635M is a 1/4-20 hex nut, 20 threads per inch, so it runs on any 1/4 inch coarse (UNC) bolt, machine screw, or threaded rod. It will not fit 1/4-28 fine thread.
2) What grade are the Metallics 1/4-20 hex nuts, and are they strong enough for strut and hanger work?
Grade 2, with a hardness of Rockwell B68 to C32. That is standard commercial-grade carbon steel hardware, fine for general strut, channel, hanger, and box mounting. If a drawing calls out Grade 5 or Grade 8 nuts for a structural or high-torque connection, this is not the right nut.
3) Can I buy fewer than 5000 of the Metallics N1635M hex nuts?
The N1635M ships as a box of 5000 and 5000 is the order minimum, so it is a bulk buy aimed at shops and MRO cribs that go through 1/4-20 hardware steadily. Metallics does offer other sizes and quantities by request if you need a smaller count or a different thread.
4) How much thread does the 1/4-20 Metallics hex nut need sticking through?
The nut stands 0.212 to 0.226 inch tall, so you want at least that much bolt protruding to get full thread engagement, and ideally a thread or two past flush.
5) Are these zinc hex nuts okay for outdoor or damp electrical work?
The N1635M is steel with a zinc finish, which handles indoor and normally dry or occasionally damp conditions. For continuous wet exposure, salt air, or direct burial, zinc plated steel will eventually corrode and stainless is the better choice.
6) Do the Metallics N1635M nuts meet Buy American and ARRA requirements on a public job?
Metallics lists the N1635M as both ARRA compliant and Buy American compliant. Country of origin is recorded as multiple, so if your contract requires documentation tied to a specific country of manufacture, ask for the paperwork on the lot you receive.
7) Is this a plain hex nut or a locknut?
The N1635M is a plain hexagonal nut, no nylon insert and no distorted thread. On vibrating equipment or anything you need to stay put without being checked, pair it with a lock washer or specify a nylon insert locknut instead.
8) How heavy is a box of 5000 Metallics 1/4-20 hex nuts, and how big is the carton?
The box weighs 34.44 lbs and measures 7.25 by 6.25 by 6 inches. Worth knowing before you put it on a shelf or send someone up a ladder with it.
