Metallics UB015 – Frequently Asked Questions
1) What pipe size does the Metallics UB015 U-bolt fit?
The UB015 is sized for 2 inch pipe. Its inside opening is 2-1/2 inches across with a 3-3/16 inch leg length, so it wraps 2 inch pipe and still leaves thread engagement for the two hex nuts at the mounting surface.
2) Does the Metallics UB015 U-bolt meet Buy American requirements for a government job?
Yes. The UB015 is flagged both ARRA compliant and Buy American compliant, which is what institutional and federally funded procurement usually asks for on fastener submittals. Country of origin is listed as multiple.
3) What thread size and nuts come with the Metallics UB015 U-bolt?
Threads are 5/16-18, right hand, cut to ANSI/ASME B1.1. Each U-bolt ships with two hex nuts, Grade A per ASTM A563, so you do not need to source nuts separately. The bolt itself is ASTM A307 steel.
4) Will a zinc plated steel U-bolt hold up on outdoor or damp mechanical work?
The UB015 is steel with a zinc finish, which is a plated coating suited to dry interior and sheltered conditions. For continuous wet exposure, salt air, or buried work, step up to stainless. Zinc plating handles the usual electrical, plumbing, heating and air conditioning service this part is listed for.
5) How many U-bolts are in a bag of Metallics UB015, and is there an order minimum?
They come bagged 10 to a bag, and the order minimum is 10 each. Metallics also makes other sizes and quantities of the UB series available by request.
6) What standards does the Metallics UB015 U-bolt and nut assembly meet for a spec submittal?
Three standards cover it: dimensions to ASME B18.2.2, threads to ANSI/ASME B1.1, and materials with the U-bolt to ASTM A307 and the nuts Grade A per ASTM A563. That is enough to satisfy a typical fastener line on a mechanical or electrical submittal.
7) How much clearance do I need behind the mounting surface for a 5/16-18 U-bolt with hex nuts?
Allow for the nut stack past your strut or bracket. The hex nuts measure 0.489 to 0.500 inch across the flats with a height of 0.258 to 0.273 inch, so roughly a half inch of thread plus washer and nut needs to clear behind the mounting face on each leg of the UB015.
8) What is the shipping weight of a 10 pack of Metallics UB015 U-bolts?
A bag runs 748 g. Useful if you are stacking several bags into a kitted material order for a riser or rack run.
