Metallics BHC74 – Frequently Asked Questions
1) Will a 5/8-11 nut thread onto the BHC74 bolt, and is the thread coarse or fine?
It is 5/8-11 UNC, 11 threads per inch, which is the coarse series for 5/8 inch diameter. Any standard 5/8-11 hex nut, coupling nut, or tapped 5/8-11 insert will take it. Threads are cut to ASME B18.2.1-1996, so it interchanges with other bolts built to that standard. Fine-thread 5/8-18 hardware will not mate.
2) Does the Metallics BHC74 hex bolt qualify for Buy American or ARRA funded jobs?
Both flags are marked compliant on the BHC74, so it can be submitted on Buy American and ARRA funded work. Country of origin is listed as multiple, so if your specification requires a single named origin on the submittal, get the origin confirmed for the lot you are receiving.
3) Is a zinc plated steel bolt like this acceptable for outdoor or damp mechanical room use?
The BHC74 is steel with a zinc finish, which is a plated coating meant for dry indoor and sheltered service. It holds up fine in mechanical rooms, electrical rooms, and above ceilings. For direct weather exposure, roof curbs, pools, or washdown areas, step up to hot dip galvanized or stainless rather than plated zinc.
4) Can I buy fewer than 100 of the BHC74 bolts?
No. The BHC74 ships as a box of 100 and the order minimum is 100 count, so the box is the smallest unit. One box weighs 31.9 lbs, worth knowing if someone is carrying it up a ladder or you are loading a van by hand.
5) Are nuts and washers included with the BHC74, or do I order those separately?
Bolts only. The box of 100 is hex bolts with no nuts or washers, so add 5/8-11 hex nuts and 5/8 flat or lock washers to the order to make a complete assembly. Match the washer and nut finish to zinc so you are not mixing coatings in the same joint.
6) I need the same bolt in a different length for the rest of my run. What do I order?
The BHC74 is the 5/8-11 x 3-1/4 inch size within the Metallics BHC and JBHC hex bolt series, and other lengths and quantities in that series are available on request. Keep the 5/8-11 thread and zinc finish consistent across the run so one socket and one nut size covers the whole install.
7) Is this hex bolt suited to electrical and mechanical trade work specifically?
Yes. Metallics lists the BHC and JBHC hex bolts for the electrical, plumbing, heating and air conditioning trades, which is exactly the strut, trapeze, hanger, and equipment mounting work those crews do. It is a general purpose zinc plated steel hex bolt rather than a structural or high strength fastener, so use it where the drawing calls for commercial grade hardware.
