Metallics UB018 – Frequently Asked Questions
1) What pipe size does the Metallics UB018 U-bolt fit?
The UB018 is sized for 1 inch pipe. The U is 3/8-16 threaded rod stock with a 1-1/2 inch inside width and 2-1/2 inch legs, so it wraps 1 inch nominal pipe and leaves thread for the two hex nuts. If you are hanging a different pipe diameter, you need a different U-bolt in the UB series rather than shimming this one.
2) Do the nuts come with the Metallics UB018 U-bolt or do I order them separately?
Two hex nuts ship with each U-bolt, so nothing extra is needed to make up the connection. The nuts are Grade A per ASTM A563 and the U-bolt itself is ASTM A307 steel. If your detail calls for a backing plate or saddle, that is a separate item.
3) Can I use the Metallics UB018 on a federally funded job with Buy American requirements?
The UB018 is flagged compliant for both Buy American and ARRA, which is what procurement on federal, municipal, and institutional projects asks for. Country of origin is listed as multiple, so if your specification requires a single named origin on the submittal, confirm the origin on the lot you receive.
4) Is the UB018 U-bolt okay for outdoor or damp mechanical rooms?
It is zinc plated steel, which is the standard finish for indoor and protected outdoor electrical and mechanical work. Zinc plating handles humidity and condensation in mechanical rooms, but for continuous wet exposure, coastal air, or chemical environments a stainless U-bolt is the better call.
5) Will standard 3/8-16 hardware thread onto this U-bolt?
Yes. The threads are 3/8-16 right hand, cut to ANSI/ASME B1.1, so any off-the-shelf 3/8-16 nut, washer, or channel fitting threads on. The supplied hex nuts conform to ASME B18.2.2 dimensionally, with a head width of 0.551 to 0.563 in. and a height of 0.320 to 0.337, so a standard 9/16 inch wrench or socket fits them.
6) What trades use a U-bolt like this, and is it only for electrical conduit?
Not electrical only. The UB series is built for electrical, plumbing, heating, and air conditioning work, so the same part clamps 1 inch conduit, 1 inch water line, or a 1 inch refrigerant or hydronic run to a strut, angle, or beam clip. It is a general-purpose pipe and conduit clamp rather than a conduit-specific fitting.
7) How much does a bag of 10 Metallics UB018 U-bolts weigh?
798 g for the pack, which matters mainly when you are ordering by the case for a large hanger layout. The assembled bolt occupies roughly 6 in. by 3 in. of space per the published product length and height, useful for sizing bin storage on the truck.
