Metallics UB045 – Frequently Asked Questions
1) What thread size are the nuts on the Metallics UB045 U-bolt?
The UB045 is a 1/2-13 U-bolt, so it takes 1/2 inch nuts with 13 threads per inch (standard UNC coarse). The threads are made to ANSI/ASME B1.1, so any off-the-shelf 1/2-13 hex nut or washer will run on it if you need spares.
2) Do the Metallics UB045 U-bolts come with nuts, or do I have to buy those separately?
Nuts are included. Each UB045 U-bolt ships with two hex nuts, one per leg, and the nuts are Grade A per ASTM A563. You still need to supply your own mounting plate or strut if the application calls for one.
3) What size pipe or conduit will a 1/2-13 x 8-3/8 x 6-3/4 U-bolt wrap?
Go by the 6-3/4 inch inside width between the legs. That clearance accepts a round run up to roughly 6-3/4 inches outside diameter, and the 8-3/8 inch leg length gives you the depth to get through a channel or bracket and still have thread for both nuts. Measure the actual outside diameter of your pipe, not the nominal trade size, since insulation or a coating eats into that 6-3/4 inches fast.
4) Does the Metallics UB045 U-bolt meet Buy American and ARRA requirements for a federal or public job?
Yes. The UB045 is flagged compliant for both Buy American and ARRA, which is what a government, school, or transit procurement file usually needs on a fastener line item.
5) How many U-bolts are in a box of Metallics UB045, and can I buy just one?
The UB045 is sold in boxes of 10, with an order minimum of 10 each. Single pieces are not a buying unit here. Other sizes and quantities can be had by request if 10 is not the count you need.
6) Will a zinc plated steel U-bolt hold up outdoors or in a wet mechanical room?
The UB045 is steel with a zinc finish, which is a plated coating meant for dry to occasionally damp indoor service. It will handle a mechanical room, but sustained exposure to weather, washdown, chlorides, or coastal air will eventually surface rust. For those conditions specify a hot dip galvanized or stainless U-bolt instead.
7) What material and dimensional standards does this U-bolt and nut assembly meet for a submittal?
Three standards cover the UB045: the U-bolt itself is ASTM A307 carbon steel, the hex nuts are Grade A per ASTM A563, and the nut dimensions follow ASME B18.2.2. Threads are ANSI/ASME B1.1. That is enough to close out most fastener submittals without a separate letter.
8) What wrench size do the hex nuts on the UB045 take?
Across the flats the nuts measure 0.736 to 0.750 inch, so a 3/4 inch wrench or socket is the fit. Nut height runs 0.427 to 0.448 inch.
