Metallics BHCS1210G Bolt 1/2-13 x 10 Sq Hd Blt &NT Galv (50 pcs)

No. Nuts are included with the BHCS1210G bolts, so each 1/2-13 bolt comes with a mating nut. Washers are not part of the pack, so order flat or lock washers separately if your connection calls for them.

They come 50 pieces to a pack, with nuts, so one pack covers 50 connections at 1/2-13. Worth knowing if you are pulling for a job and only need a handful, since this is a bulk pack rather than a single bolt.

Galvanized is the corrosion-resistant finish used for exterior and damp-location work, which is what the BHCS1210G carries. It is the usual choice for outdoor framing, strut, pole line and utility hardware. For submerged, coastal splash, or chemical exposure, stainless is the better call.

At 10 inches overall length, the BHCS1210G handles deep stack-ups, timber-to-timber connections, through-bolting heavy framing or crossarms, and multiple layers of channel or plate. Remember the nut needs thread engagement at the far side, so your total grip should be short enough to leave the nut fully on the threads.

Both are driven with a wrench, but a square head gives four flats instead of six, which is traditional on utility, pole line and timber hardware and takes a square-socket or open-end wrench well in tight quarters. The BHCS1210G is the square head version in 1/2-13 x 10, galvanized with nuts. If your spec or the existing hardware on the structure calls out hex, order a hex bolt instead; the thread and finish are the same but the head will not match.

A 1/2 inch diameter bolt like the BHCS1210G goes through a 9/16 inch hole in steel or plate for normal clearance, and 1/2 inch nominal in wood where a tight fit is wanted. The 1/2-13 designation is the thread, not the hole size.
