Metallics BHC81 – Frequently Asked Questions
1) What size and thread is the Metallics BHC81 hex bolt?
It's a 3/4-10 x 3 inch hex bolt: 3/4 inch nominal diameter with 10 threads per inch (coarse UNC), and a 3 inch length. Measured shank diameter runs 0.729 to 0.768 inch. Thread form follows ASME B18.2.1-1996, so it mates with standard 3/4-10 nuts and tapped holes.
2) Do these Metallics bolts meet Buy American or ARRA requirements for a federal job?
No. The BHC81 is not Buy American compliant and is not ARRA compliant; country of origin is listed as multiple. On a federally funded project with domestic sourcing language in the spec, this bolt won't qualify.
3) What wrench or socket size fits the head on the Metallics BHC81?
Head width across flats measures 1.088 to 1.125 inch, so a 1-1/8 inch wrench or socket is the one you want. Head height is 15/32 inch, which matters if you're working in a tight channel or under a flange. Across corners the head runs 1.240 to 1.299 inch.
4) Is the zinc plating on these hex bolts OK for outdoor or damp locations?
The zinc plated steel finish on the BHC81 handles indoor and protected damp environments. It is electroplated zinc, not hot-dip galvanized, so for sustained outdoor exposure, coastal air, or wet process areas, specify a hot-dip galvanized or stainless bolt instead.
5) How many bolts come in a box of Metallics BHC81?
They ship 50 pieces to a box, and 50 each is the order minimum. If you need a different count, other quantities in the hex bolt series can be arranged on request.
6) Are nuts and washers included with the BHC81 hex bolts?
The box contains bolts only, 50 pieces. Order 3/4-10 hex nuts and 3/4 inch flat or lock washers separately to complete the assembly.
7) What trades use the Metallics BHC and JBHC hex bolts?
The series is sold into the electrical, plumbing, heating and air conditioning trades, where 3/4-10 hex bolts get used for hanging and bracing gear, bolting strut and channel, mounting transformers and pumps, and general equipment anchorage. It's a standard MRO stocking item rather than a specialty fastener.
