Metallics HTB42M – Frequently Asked Questions
1) Are these zinc plated steel bolts okay for outdoor or damp locations?
These are zinc plated carbon steel. Zinc plating is fine for dry interior work and gives moderate protection in occasionally damp areas, but it is not a marine or continuously wet finish. For wash-down areas, roof work, or coastal exposure, go to an 18-8 stainless hex tap bolt in the same 1/4-20 x 2 size instead.
2) How strong are these bolts - will they hold a hanger or trapeze rod load?
Tensile strength is 60,000 psi minimum with hardness at Rockwell B69-B100, which is a standard commercial-grade carbon steel bolt. That covers typical electrical and mechanical support work: strut connections, conduit hangers, equipment mounting. If your drawing calls out a higher grade bolt for a structural or seismic connection, this is not that bolt.
3) Do I have to buy 2000 of these, or can I get a smaller quantity?
HTB42M ships as a box of 2000 pieces, and 2000 is the order minimum for that item number. Other sizes and quantities in the HTB series are available by request, so if you need a 100-count or a different length, ask rather than buying a full box.
4) What size wrench or socket fits the head on this 1/4-20 hex tap bolt?
Head width across flats runs 0.425 to 0.438 inches, so a 7/16 inch wrench or socket is the fit. That is the standard hex size for a 1/4 inch bolt, which matters if you are working in a crowded panel or strut run and need to know the swing clearance before you commit.
5) Do these bolts meet Buy American or ARRA requirements on a public job?
The HTB42M is flagged compliant for both Buy American and ARRA in the manufacturer data, while country of origin is listed as China. If your project specification requires domestic melt and manufacture rather than the compliance flag, get the documentation reviewed before you submit it.
6) Does a hex tap bolt come with nuts and washers, or do I order those separately?
HTB42M is the bolt only, boxed loose. Nuts, flat washers, and lock washers are separate line items. If you are threading into a strut channel nut or a tapped hole you may not need a nut at all, which is the usual reason a tap bolt gets specified over a bolt-and-nut assembly.
7) How much does a box of 2000 of these 1/4-20 x 2 inch tap bolts weigh and how big is the carton?
A full box runs 56.8 lbs, and the carton measures 11.5 in length by 11.5 in width by 10.75 in height. Worth knowing if you are staging material on an upper floor or planning a van load, since that is a one-hand-awkward box rather than a light one.
8) Which Metallics series does HTB42M belong to and what is the difference within it?
HTB42M sits in the HTB, JHTB, and JSHTB hex tap bolt series. The HTB prefix is the zinc plated steel line, which is what this 1/4-20 x 2 item is. Order by the full item number, since length and diameter are both encoded in it.
