Metallics UBS018 – Frequently Asked Questions
1) What pipe or conduit size does the Metallics UBS018 3/8-16 U-bolt wrap?
The UBS018 is sized 3/8-16 x 2-1/2 x 1-1/2, so the inside opening between the legs is 1-1/2 inches and the threaded legs run 2-1/2 inches. That makes it a clamp for round stock or pipe up to about 1-1/2 inches across the outside diameter, not nominal pipe size. Measure the actual OD of what you are strapping before ordering.
2) Is the Metallics UBS018 U-bolt stainless, and can it go outdoors or in a wet location?
It is 18-8 stainless steel, nuts included, which is the standard austenitic grade used for general corrosion resistance outdoors, in damp mechanical rooms, and in wash-down areas. For chloride-heavy coastal or pool chemical exposure, 316 is the better choice.
3) Do the hex nuts come with the Metallics UBS018 U-bolt or do I buy them separately?
Two hex nuts ship with each U-bolt, so nothing extra is needed to land it. The nuts are made to ASTM F594, the standard for stainless steel nuts, and the bolt threads are 3/8-16 right hand, 16 threads per inch, per ANSI/ASME B1.1. You still supply any backing plate, strut, or saddle the job calls for.
4) How many U-bolts are in a bag of Metallics UBS018?
Ten pieces per bag, and 10 EA is the order minimum, so a bag is the smallest quantity you can buy. Bag weight is listed at 807 g. Metallics offers other sizes and quantities by request.
5) Will the Metallics UBS018 U-bolt meet a Buy American requirement on a federal or institutional job?
It is flagged both ARRA compliant and Buy American compliant. Country of origin is listed as multiple, so if your specification requires documentation tied to a single country of manufacture, request the cert for the lot you receive.
6) Can I use a stainless U-bolt like the Metallics UBS018 for HVAC and plumbing hangers, or is it electrical only?
Field application covers the electrical, plumbing, heating and air conditioning industries. Electricians use it to strap conduit and rigid runs; plumbers and HVAC contractors use the same bolt on pipe, trapeze hangers, and equipment mounting. It is a general mechanical clamp, not a conduit-specific fitting.
7) What size socket or wrench fits the nuts on the Metallics UBS018 3/8-16 U-bolt?
Across-flats width on the nuts is 0.551 to 0.563 in., which is a 9/16 inch wrench or socket. Nut height runs 0.320 to 0.337. Dimensions follow ASME B18.2.2, the hex nut dimensional standard, so standard tooling fits.
8) Will stainless U-bolts react with galvanized or black iron pipe?
Pairing 18-8 stainless hardware directly against galvanized or plain steel pipe sets up galvanic contact, and in wet locations the zinc or steel corrodes first. Where that matters, use an isolating felt or plastic liner between the U-bolt and the pipe. On dry interior runs it is not usually a concern.
