Metallics HTB83 – Frequently Asked Questions
1) What size and thread is the Metallics HTB83 hex tap bolt?
The HTB83 is a 3/4-10 x 3-1/2 inch hex tap bolt, so 3/4 inch diameter with 10 threads per inch, which is standard UNC coarse thread for that diameter. It is threaded to accept standard 3/4-10 nuts or a tapped 3/4-10 hole.
2) Is the HTB83 bolt okay to use outdoors or in a damp location?
The HTB83 is zinc plated steel. Zinc plating handles indoor and sheltered conditions and incidental moisture, but it is not hot-dip galvanized or stainless. For direct weather exposure, wet process areas, or coastal and chemical environments, specify an 18-8 stainless hex tap bolt in the same 3/4-10 x 3-1/2 size instead.
3) Does the Metallics HTB83 meet Buy American and ARRA requirements for a federally funded job?
Both flags are marked compliant on the HTB83: Buy American compliant and ARRA compliant. Country of origin is listed as multiple, so if your contract requires a single documented origin for the lot you receive, request that confirmation against the shipment.
4) What is the difference between a hex tap bolt and a regular hex cap screw?
A hex tap bolt like the HTB83 is threaded full length, or very nearly so, instead of carrying a plain shank under the head. That matters when you are threading into a tapped hole, a channel nut, or a strut insert, and when grip length varies between pieces of your assembly. A hex cap screw with a partial thread is the choice when you want the unthreaded body bearing in a shear joint. For a 3-1/2 inch length at 3/4-10, the full thread gives you flexibility in how deep you engage.
5) What wrench or socket size fits the HTB83 bolt head?
Head width across flats runs 1.088 to 1.125 inches, so a 1-1/8 inch socket or wrench is the fit. The head is a standard hex pattern, not a flange or washer head.
6) How many bolts come in a box of HTB83, and is there a minimum order?
HTB83 ships as a box of 25, and 25 count is the order minimum, so the box is the buying unit. Shipping weight on the box is 13.4 lbs. Other sizes and quantities of the hex tap bolt can be had by request.
7) What thread standard do these Metallics hex tap bolts conform to?
Threads are made to IFI-199 (2014). That is the industry fastener standard for the thread form, so a 3/4-10 nut, coupling, or tapped hole cut to standard UNC dimensions will take it without chasing.
8) Is the HTB83 the same bolt as the JHTB and JSHTB versions?
They belong to the same Metallics hex tap bolt family, HTB, JHTB and JSHTB. HTB83 itself is the zinc plated steel 3/4-10 x 3-1/2. If you need the stainless equivalent for corrosion service, or a different plating, order from the matching series rather than assuming the HTB part number covers it.
