Metallics UBS022 – Frequently Asked Questions
1) What size pipe or conduit will the Metallics UBS022 u-bolt wrap around?
The UBS022 is a 3/8-16 u-bolt built to 3-1/8 x 2-1/2 inch dimensions, so the 2-1/2 inch figure is the span between the legs. Measure the actual outside diameter of what you are clamping, not the nominal trade size, and leave room for any strut, saddle or insulation between the bolt and the run. If your OD is larger than that span, you need the next size up rather than forcing this one.
2) Is the Metallics UBS022 u-bolt stainless, and can it go outdoors or in a wet area?
It is 18-8 stainless steel, nuts included, which is the austenitic grade normally specified for damp, washdown and exterior hanging work where plated carbon steel would rust. Fastener material conforms to ASTM F594. For chloride-heavy environments such as pool rooms or coastal exposure, stainless still outperforms zinc but galvanic contact with dissimilar metal supports should be isolated.
3) Does the UBS022 u-bolt come with nuts, or do I have to order them separately?
Two hex nuts ship with each u-bolt, so nothing else is needed on the fastener side. What is not included is the mounting member: you still supply the strut, channel, angle or bracket the legs pass through, plus washers if your support requires them.
4) What thread does the UBS022 take, and will my existing nuts fit it?
Threads are 3/8-16 right hand, 16 threads per inch, cut to ANSI/ASME B1.1. That is standard 3/8 inch UNC, so any 3/8-16 nut or washer from your stock will thread on. Stay with stainless nuts to avoid mixing a plated steel nut onto a stainless thread.
5) Will the UBS022 u-bolt satisfy a Buy American or ARRA requirement on a public job?
The UBS022 is flagged both ARRA compliant and Buy American compliant in Metallics' data, which is what a government, school or healthcare procurement file usually needs on the submittal. Country of origin is listed as multiple, so if your specification demands a single named origin, confirm the origin on the lot you receive.
6) How many u-bolts are in a bag of Metallics UBS022, and is there a minimum order?
Packaging is a bag of 10, and the order minimum is 10 each, so a single bag is the smallest buy. Useful if you are hanging a repetitive run and want the whole clamp set from one pack rather than counting loose hardware.
7) What trades use a 3/8-16 stainless u-bolt like this, and what nut dimensions should I plan clearance for?
Metallics lists the application as electrical, plumbing, heating and air conditioning work, so it is a general hanging and clamping bolt for conduit, pipe and equipment supports rather than a structural anchor. The supplied hex nuts measure 0.551 to 0.563 inch across the flats and 0.320 to 0.337 inch high, to ASME B18.2.2, which is what to allow for socket access behind a tight support.
8) Can I get the Metallics UBS u-bolt in other sizes or a larger quantity than the 10-pack?
Yes. The UBS series covers other sizes and pack quantities beyond the 3/8-16 x 3-1/8 x 2-1/2 bag of 10, available on request. Give the leg thread size, the inside span you need and the count, and the right UBS number can be pulled.
