Metallics BHC108 – Frequently Asked Questions
1) What thread size and pitch is the Metallics BHC108 hex bolt?
It's a 7/8-9 bolt: 7/8 inch nominal diameter with 9 threads per inch, which is standard UNC coarse thread at that diameter. Measured thread outside diameter runs 0.852 to 0.895 inch. Overall length is 4 inches. So any 7/8-9 nut or tapped hole takes it.
2) Will a box of these 7/8 x 4 bolts count against a Buy American or ARRA job?
Country of origin is China. The record flags both ARRA and Buy American compliance as C, so if your project has a domestic-content clause, treat that flag as the item to confirm with your spec reviewer before you submit it, because origin and compliance status need to agree on the submittal.
3) Do the Metallics BHC108 bolts meet a recognized dimensional standard for inspection?
They're made to ASME B18.2.1-1996, the dimensional standard for inch-series hex bolts and screws. That covers head width across flats, head height, thread and length tolerances, which is what an inspector or spec reviewer is checking against.
4) Are these bolts okay for outdoor or damp mechanical room use?
They're steel with a zinc finish, which gives moderate corrosion resistance for indoor, mechanical room and sheltered exterior work. Zinc plating is not a marine or continuously wet-location coating, so for a roof, a cooling tower deck or anything with chronic moisture or chemical exposure, specify hot-dip galvanized or stainless instead.
5) How many bolts come in a box and can I buy just a few?
They ship as a box of 25, and 25 is the order minimum, counted in each. There's no single-piece break on this size. Other sizes and quantities can be had by request.
6) Do nuts and washers come with the BHC108 bolts?
No. The box of 25 is bolts only, so order 7/8-9 hex nuts and 7/8 flat or lock washers separately if the connection needs them. The 4 inch length has to cover your total grip plus washer stack plus enough thread for the nut.
