Metallics HTB47M – Frequently Asked Questions
1) What thread does the Metallics HTB47M hex tap bolt use, and will it thread into a standard 1/2-13 nut or tapped hole?
It's a 1/2-13 bolt, 13 threads per inch, which is the standard UNC coarse pitch for 1/2 inch. It will mate with any standard 1/2-13 nut or a tapped 1/2-13 hole, such as a 1/2 inch threaded strut channel nut. Threads are made to IFI-199 (2014).
2) How strong is the Metallics HTB47M hex tap bolt?
Minimum tensile strength is 60,000 psi with a hardness of Rockwell B69 to B100. That is a general purpose, low carbon grade, fine for strut, hanger, and equipment mounting work. If your drawing calls out a higher grade bolt (for example a specified minimum tensile above 60 ksi), this is not the fastener for that connection.
3) Can I buy the HTB47M hex tap bolt in less than a full box?
No. It ships as a box of 1,000 with an order minimum of 1,000 pieces, so the full box is the buying unit. Other sizes and quantities are available by request.
4) Is a hex tap bolt threaded all the way to the head, or is there a shank?
A tap bolt is fully threaded to the head, which is what separates it from a standard hex cap screw with a partial thread and an unthreaded grip length. That makes the HTB47M useful when you need thread engagement right up at the clamped surface, or when you want to run a nut all the way up. The HTB47M is the 1/2-13 by 1-1/2 inch size.
5) What size wrench or socket fits the head on this 1/2-13 hex tap bolt?
Head width across flats runs 0.725 to 0.750 inch, so a 3/4 inch wrench or socket is the right tool. Head type is a standard hex.
6) Is this bolt suitable for outdoor or damp electrical installs, or should I go stainless?
The HTB47M is zinc plated steel. Zinc handles indoor and normally dry or occasionally damp conditions, but in wet, coastal, or corrosive environments the plating will eventually give up and 18-8 stainless is the better call. Same hex tap bolt family is offered in 18-8 stainless as well.
7) Does this bolt meet Buy American or ARRA requirements on a federally funded job?
The HTB47M is flagged ARRA compliant and Buy American compliant in the manufacturer data, with a country of origin of China. On a federal or federally funded project, submit it against the specific clause in your contract, since the applicable domestic content rule varies by program.
8) How much does a box of 1,000 of these 1/2 inch tap bolts weigh for freight and handling?
Right around 104.9 lbs for the box. Worth knowing before you have someone carry it up a lift or route it as a parcel.
