Metallics UB021PL – Frequently Asked Questions
1) What thread size are the nuts on the Metallics UB021PL U-bolt, and how many come with each bolt?
The UB021PL is a 3/8-16 U-bolt, so 16 threads per inch on a 3/8 inch diameter leg, cut to the ANSI/ASME B1.1 thread standard. Two nuts ship with each bolt, one per leg, so you do not need to source hardware separately. Threads at 16 TPI are standard 3/8 coarse, which is what a common 3/8-16 nut or rod coupling will mate with.
2) Does the Metallics UB021PL U-bolt come with a mounting plate, or do I have to buy that separately?
A plate is included. The UB021PL is supplied as a U-bolt with plate and nuts, so you get the saddle plate that sits over the pipe or conduit and the two nuts that clamp it down. Nothing else is needed to make the clamp up, though you still supply whatever structure or strut the legs pass through.
3) What are the dimensions of the UB021PL U-bolt, and will it clamp my conduit?
The UB021PL is a 3/8-16 x 2-5/8 x 2 U-bolt. The 2 inch figure is the inside width between the legs, which is what has to clear the outside diameter of the pipe or conduit you are strapping, and 2-5/8 is the leg length that has to pass through your strut or bracket and still leave thread for the two nuts. Measure the actual OD of your conduit, not its trade size, since trade size and OD are not the same number.
4) Do Metallics UB021PL U-bolts meet Buy American or ARRA requirements for a government job?
No on both counts. The UB021PL is flagged as not Buy American compliant and not ARRA compliant, even though its country of origin is listed as the United States. If your contract carries a Buy American or ARRA clause, this part will not satisfy the submittal and you need a fastener certified to that requirement.
5) How many U-bolts are in a bag of Metallics UB021PL, and is there a minimum order?
They are bagged 10 to a bag, and the minimum order is 10 each. So the smallest quantity you can take is one bag of ten, which is how most electrical and MRO stockrooms buy U-bolts for conduit and pipe runs anyway.
6) Is the Metallics UB021PL U-bolt rated steel, and what finish is on it?
Steel, zinc plated. The U-bolt itself is made to ASTM A307 and the nuts are Grade A per ASTM A563. Zinc plating suits dry interior and protected locations; for direct weather exposure, chemical service, or wet process areas, a hot dip galvanized or stainless U-bolt is the better call.
7) I need a different size U-bolt than the 3/8-16 x 2-5/8 x 2 UB021PL. Can I get one?
Yes. The Metallics UB series runs in other sizes and other bag quantities beyond the UB021PL, available by request, so if your pipe OD or leg length does not match this one, give the diameter, thread, inside width and leg length you need and it can be quoted.
