Metallics UBS016 – Frequently Asked Questions
1) Is this U-bolt stainless, and can it go outdoors or in a wet area?
The UBS016 is 18-8 stainless steel, the common austenitic grade used where plated carbon steel would rust. That makes it suitable for damp, outdoor, and washdown locations. For chloride-heavy coastal or pool chemistry, 316 is the grade normally specified instead.
2) Do the Metallics UBS016 U-bolts meet Buy American and ARRA requirements for a public project?
Both are flagged compliant on the UBS016, which matters on federally funded and public-agency work where fastener sourcing gets audited. Country of origin is listed as multiple, so confirm the origin marking on the bag you receive against your submittal.
3) Are the hex nuts included with the Metallics UBS016 U-bolt?
Yes, two hex nuts ship with each U-bolt, so nothing extra is needed to make up the joint. If your detail calls for a saddle or backing plate, that is a separate item.
4) What standards do these 5/16-18 stainless U-bolts and nuts conform to?
Threads are cut to ANSI/ASME B1.1, right hand, 18 threads per inch. The hex nut dimensions follow ASME B18.2.2 and the nut material follows ASTM F594 for stainless fasteners. That combination means standard 5/16-18 stainless nuts and washers from stock will thread on.
5) How many U-bolts come in a bag and is there an order minimum?
The UBS016 is bagged 10 per pack, with a minimum order of 10 each. Other sizes and quantities can be supplied by request.
6) Is this U-bolt intended for conduit and pipe hanging work?
It is catalogued for electrical, plumbing, heating and air conditioning field use, which covers conduit runs, pipe supports, mounting to strut, and securing equipment to a rail or post. The 3 inch inside width sets the largest thing it will go around.
7) What wrench or socket size do the nuts on this U-bolt take?
Nut width across flats runs 0.489 to 0.500 inch with a height of 0.258 to 0.273 inch, so a 1/2 inch wrench or socket fits. Stainless galls easily when run down fast, so turn them slow or use an anti-seize.
