Metallics BHC88M – Frequently Asked Questions
1) What size is the Metallics BHC88M hex bolt, and what nut or tapped hole does it thread into?
The BHC88M is a 3/8-16 x 1/2 inch hex bolt, so it threads into anything tapped 3/8-16: 16 threads per inch on a nominal 3/8 inch diameter. Measured shank diameter runs 0.360 to 0.388 inch. At a 1/2 inch length it is a short bolt, intended for clamping thin material such as strut, channel, brackets and enclosure flanges rather than deep stack-ups.
2) How many bolts come in a box, and can I buy fewer than a full box?
BHC88M ships as a box of 1000 pieces, and 1000 is the order minimum, so it is sold as a full box rather than loose counts. Metallics notes other sizes and quantities are available by request if 1000 of this size is more than the job needs.
3) Are these bolts dimensionally standard, or a proprietary Metallics size?
They are made to ASME B18.2.1-1996, the standard for square and hex bolts and screws. That means head dimensions and thread are interchangeable with any other B18.2.1 3/8-16 hex bolt, so they drop into existing hardware without special tooling.
4) Will zinc plated steel bolts hold up outdoors or in a damp mechanical room?
These are steel with a zinc finish. Zinc plating is a mild corrosion coating suited to indoor and sheltered work: panel builds, strut, enclosure and conduit support inside a building or a covered mechanical space. For continuous wet exposure, coastal air, or direct ground contact, specify hot dip galvanized or stainless instead, because plated zinc wears through at the wrench marks and thread crests first.
5) Do these bolts come with nuts and washers?
No. The BHC88M box contains 1000 hex bolts only, no nuts, flat washers or lock washers. Order 3/8-16 hex nuts and 3/8 washers separately in a matching zinc finish so the plating does not become the weak point of the joint.
6) How much does a box of 1000 of these 3/8 hex bolts weigh and how big is the carton?
A box runs 28.72 lbs, with carton dimensions of 9 x 9 x 6.13 inches. Worth knowing if you are staging fastener stock on a cart or shipping multiple boxes to a jobsite trailer, since a pallet of them gets heavy fast.
7) Where are Metallics BHC series hex bolts made?
Country of origin on the BHC88M is China. If your project is working to a domestic sourcing requirement, that origin is the figure your submittal package needs.
