Metallics UBG015 – Frequently Asked Questions
1) What thread size and pitch are the nuts on the Metallics UBG015 U-bolt?
The UBG015 U-bolt is threaded 5/16-18, that is 18 threads per inch in UNC coarse thread per ANSI/ASME B1.1. Any standard 5/16-18 coarse hex nut or washer will run on the legs, so spares are easy to source. Two hex nuts ship with each U-bolt.
2) Do nuts come with the UBG015 U-bolt or do I have to order them separately?
Nuts are included. Each Metallics UBG015 is a U-bolt with hex nuts, two per bolt, so there is nothing extra to buy to make the connection. Saddles or mounting plates, if your detail calls for them, are not part of the assembly.
3) Can I use the Metallics UBG015 U-bolt on a federally funded or government job?
It is flagged both ARRA compliant and Buy American compliant, which is what most public agency and federally funded specs ask for on fasteners. Country of origin is listed as multiple, so confirm the origin on the lot you receive if your contract requires documentation per shipment.
4) Is the Metallics UBG015 U-bolt OK for outdoor or damp locations?
It is galvanized steel, so it holds up in exterior and damp interior work far better than plain finish. For continuous saltwater or heavy chemical exposure, stainless is the better call; galvanized is the standard choice for exterior conduit, pipe, and strut anchoring.
5) How many U-bolts come in a bag of Metallics UBG015 and what is the minimum order?
UBG015 is bagged, and the minimum order is 10 each. Count on a 10-piece bag per order line when you are pricing out a run of pipe or conduit supports.
6) What dimensional standard do the hex nuts on the UBG015 follow, and will a standard wrench fit?
The nuts are made to ASME B18.2.2, the standard dimensional spec for hex nuts, with a measured head width across flats of 0.489 to 0.500 inch and a height of 0.258 to 0.273 inch. That is a nominal 1/2 inch across flats, so a standard 1/2 inch wrench or socket seats on them.
7) I need a different U-bolt size than the UBG015. Does Metallics make other sizes in the UBG series?
Yes. The UBG series of galvanized U-bolts with hex nuts runs in other sizes and pack quantities beyond the 5/16-18 UBG015, available by request. Give the rod diameter, the inside width you need to clear the pipe, and the leg length, and the matching UBG part can be pulled.
