Metallics BHC7612G Bolt 3/4 x 1-1/2 HXBT HDG (25 pcs)

The BHC7612G is a 3/4 inch diameter hex bolt with a 1-1/2 inch length, so it's a short, heavy-diameter bolt for thick-material connections rather than deep through-bolting. Check your total grip (material thickness plus washer and nut) before ordering, since 1-1/2 inches of bolt leaves little room once a nut and washers are added.

Yes, the BHC7612G is hot dip galvanized (HDG), the heavier zinc coating used on exterior strut, channel, and structural steel connections where electroplated zinc would corrode too quickly. Pair it with hot dip galvanized nuts and washers so the coatings match and thread fit is correct.

Twenty-five bolts per pack. That's a box quantity, so electrical and MRO buyers stocking a van or a job crib get one carton rather than loose pieces. Nuts and washers are not part of the pack, only the bolts.

A hex bolt such as the 3/4 x 1-1/2 BHC7612G has a six-sided head you drive with a wrench or socket, so you can hold the head and torque the nut on either side. A carriage (round-head square-neck) bolt is meant to pull itself tight into wood or a slot and leave a smooth head exposed. For bolted steel-to-steel electrical framing, the hex head is what you want because it gives you a positive wrench grip on both ends.

You'll need 3/4 inch hot dip galvanized hex nuts and, in most cases, 3/4 inch HDG flat washers (plus a lock washer if the joint sees vibration). None of those are included with the bolts. Match the 3/4 inch size and the hot dip galvanized finish so you don't create a dissimilar-coating joint outdoors.
