Metallics BHC105 – Frequently Asked Questions
1) What thread does the Metallics BHC105 hex bolt take, and will a standard 7/8 nut fit it?
The BHC105 is a 7/8-9 hex bolt, 9 threads per inch, cut to ASME B18.2.1-1996. That is the standard UNC coarse pitch for 7/8 inch diameter, so any off the shelf 7/8-9 UNC hex nut or coupling will thread onto it. Measured thread major diameter runs 0.852 to 0.895 inch.
2) Is the 2-1/4 inch length of the Metallics BHC105 enough grip for my connection?
At 2-1/4 inches overall under the head, the BHC105 is a short bolt for its 7/8 inch diameter, so most of that length carries thread. Figure your total stack (strut, bracket, washers) plus enough protruding thread to fully engage the nut. For thicker assemblies you need a longer 7/8-9 bolt; Metallics builds the BHC and JBHC hex bolt series in other lengths.
3) Does the Metallics BHC105 hex bolt meet Buy American and ARRA requirements on a public job?
Metallics flags the BHC105 as both Buy American compliant and ARRA compliant in its product record. Country of origin on the part is China. Procurement officers on federally funded work should weigh both of those facts against the specific clause in their contract, since the applicable rule varies by program.
4) Will a zinc plated steel hex bolt like this hold up outdoors or in a damp mechanical room?
The BHC105 is steel with a zinc finish. Zinc plating is a mild corrosion coating suited to indoor and protected work: electrical rooms, plumbing and HVAC equipment mounting, which is what Metallics targets this bolt at. For sustained outdoor exposure, washdown, or coastal air, step up to hot dip galvanized or stainless.
5) Can I buy the Metallics BHC105 individually or do I have to take the whole box?
It ships as a box of 50 with a 50 count order minimum, so the box is the buying unit. That full box weighs 28.92 lbs. If you need a different quantity or a different size in the same hex bolt family, Metallics offers other sizes and quantities by request.
6) Does the BHC105 box include nuts and washers?
No. The box of 50 is bolts only, hex head, 7/8-9 x 2-1/4 in zinc plated steel. Order matching 7/8-9 UNC hex nuts and 7/8 inch washers separately to complete the connection.
7) Is this the right bolt for hanging pipe and conduit supports?
Yes, that is the intended use. Metallics sells the BHC and JBHC hex bolts into the electrical, plumbing, heating and air conditioning trades, for bolting brackets, hangers, and supports. The BHC105 is the 7/8-9 x 2-1/4 size in zinc plated steel.
