Metallics UBS09 – Frequently Asked Questions
1) Is the Metallics UBS09 U-bolt stainless, and will it hold up outdoors?
It is 18-8 stainless steel, bolt and both nuts, which is the standard austenitic grade used for outdoor and damp-location clamping. For rooftop conduit runs, mechanical rooms, or washdown areas it will not rust-stain the way a plated carbon steel U-bolt does. The nuts conform to ASTM F594, the spec for stainless steel nuts.
2) What size hole do I drill for a 1/4-20 U-bolt, and what wrench fits the nuts?
The legs are 1/4-20 thread, right hand, cut to ANSI/ASME B1.1, so a 1/4 inch bolt clearance hole is what you drill in the strut or plate, spaced to the 2 inch inside width. The supplied hex nuts measure 0.428 to 0.438 inch across the flats and 0.212 to 0.226 inch high, which is a 7/16 inch wrench or socket.
3) How many nuts come with each Metallics UBS09 U-bolt, and how many bolts are in a bag?
Two hex nuts ship with each U-bolt, one per threaded leg, so you do not need to buy nuts separately. They are bagged with a minimum order of 10 each, so the smallest purchase is a bag of ten complete U-bolt and nut sets. No saddle or mounting plate is included.
4) Will a Metallics UBS09 U-bolt meet a Buy American requirement on a government or institutional job?
The UBS09 is flagged compliant for both Buy American and ARRA, which is what a government, school, or healthcare procurement spec usually asks for on fasteners. Country of origin is listed as multiple, so if your contract requires a specific country of manufacture, that is the detail to confirm with the submittal.
5) Can I use this stainless U-bolt for plumbing or HVAC pipe, or is it only an electrical fastener?
It is catalogued for electrical work but the stated field application covers electrical, plumbing, heating, and air conditioning. The same 1/4-20 stainless U-bolt and nut set clamps copper or steel pipe, refrigerant line, and tube hangers as readily as conduit. What limits it is the 2 inch inside width, not the trade.
6) I need a different U-bolt size than 3-1/4 by 2 inches. Does the Metallics UBS series cover other sizes?
The UBS series runs other sizes and pack quantities beyond the 3-1/4 by 2 inch UBS09, available by request. If your conduit or pipe OD does not land near the 2 inch inside spread, ask for the size that matches rather than forcing this one, since an oversized U-bolt will not clamp and an undersized one will not close.
7) What standards do the Metallics UBS09 U-bolt and nuts conform to for a submittal package?
Three specs are stated: dimensions to ASME B18.2.2 (hex nut dimensions), nut material to ASTM F594 (stainless steel nuts), and threads to ANSI/ASME B1.1 (unified inch screw threads). Material is 18-8 stainless. That is usually enough to clear a spec section calling for stainless steel U-bolts with hex nuts.
