Metallics HTB59M – Frequently Asked Questions
1) How strong is the Metallics HTB59M bolt, and is it a graded fastener?
It is a low carbon steel bolt rated at 60,000 psi minimum tensile strength, with hardness in the Rockwell B69 to B100 range. That is general purpose strength for hanging, strut, and support work. For high load structural connections you want a higher strength grade instead.
2) Will a zinc plated steel tap bolt hold up outdoors or in a wet location?
The HTB59M is steel with a zinc finish, which is a plated coating meant for dry interior and protected service. It will corrode in persistent wet, coastal, or washdown conditions. For those openings step up to a stainless bolt, which the same Metallics hex tap bolt family offers in 18-8 stainless.
3) Is a Metallics hex tap bolt threaded all the way to the head?
Yes. A hex tap bolt is fully threaded from the point right up under the hex head, unlike a hex cap screw that carries an unthreaded shoulder. That is what makes the HTB59M useful for threading into strut nuts, tapped plates, and beam clamps where you want thread engagement across the full 1-1/4 inch grip.
4) How many bolts come in a box of Metallics HTB59M, and can I buy fewer?
It ships as a box of 1,000, and 1,000 is the order minimum, so it is a bulk buy rather than a count-out item. Metallics does make other sizes and pack quantities in this hex tap bolt line on request.
5) How much does a box of 1,000 Metallics 3/8-16 x 1-1/4 hex tap bolts weigh?
The full box runs 53.44 lbs. Worth knowing if you are staging material on a lift or carrying it up to a mechanical room, since it is a single heavy carton rather than a light shelf pack.
6) Do Metallics hex tap bolts meet a recognized thread standard for submittals?
Threads are made to IFI-199 (2014). If a spec sheet or submittal package asks you to name the dimensional standard for the fastener threads, that is the reference to cite for the HTB series.
7) Where are Metallics HTB59M hex tap bolts made?
Country of origin is China. Government and institutional buyers with domestic sourcing requirements on a project should weigh that against the procurement rules governing the job before standardizing on this item.
