Metallics G5HTB72 – Frequently Asked Questions

1) Is the Metallics G5HTB72 tap bolt threaded all the way to the head?
Yes. A hex tap bolt is fully threaded from the point to the underside of the hex head, which is what separates it from a hex cap screw with a partial thread. On the G5HTB72 that full thread runs the entire 4 inch length at 5/8-11 UNC, right hand. Full thread is what you want when you are bolting into a tapped hole in a motor base or a frame and need the engagement depth rather than a shoulder.
2) What size hole do I need to drill and tap for a 5/8-11 hex tap bolt?
Measured shank outside diameter is 0.6170 to 0.6250 inch, so a tapped 5/8-11 hole is what this threads into. For a through hole clearance instead of a tapped hole, a standard 11/16 inch bit gives normal clearance on a 5/8 bolt. Thread is right hand.
3) Will zinc plated steel bolts hold up outdoors or in a wet mechanical room?
The finish here is zinc plating over steel, which handles indoor mechanical rooms, equipment pads, and sheltered conditions. Zinc is a sacrificial coating, so sustained wet exposure, washdown, or coastal air will eventually take it. For those openings move to 18-8 stainless or hot dip galvanized in the same 5/8-11 x 4 size.
4) How many bolts come in a box of Metallics G5HTB72, and can I buy fewer?
They ship in a box of 50, and 50 count is the order minimum, so that box is the smallest quantity. Metallics does list other sizes and quantities on request if a 50 piece box of 5/8-11 x 4 is more than the job needs.
5) Does this bolt meet ASME B18.2.1, and what thread standard should I cite on a submittal?
Threads and head dimensions follow ASME B18.2.1-2012, the dimensional standard for square and hex bolts and screws. Material falls in the AISI 1008-1026 range. For a submittal, call it a 5/8-11 x 4 Grade 5 zinc plated hex tap bolt to ASME B18.2.1-2012, Metallics part G5HTB72.
6) Is the Metallics G5HTB72 Buy American and ARRA compliant for a government or institutional job?
Metallics lists this bolt as both Buy American compliant and ARRA compliant. Country of origin is China. If your contract clause requires domestic melt and manufacture rather than the broader compliance flag, verify against the specific clause in your spec before you submit it.
7) What is a hex tap bolt actually used for on electrical and mechanical work?
The common use is mounting a motor to machinery, bolting equipment to a frame or base, and automotive and truck repair. Because the shank is threaded end to end, it works where the bolt threads directly into a tapped boss and you cannot rely on a plain grip length. In a 5/8-11 x 4 size that covers motor feet, bracket mounting, and heavier equipment anchoring.
8) How much does a box of 50 of these 5/8-11 x 4 bolts weigh for shipping?
A box of 50 comes in at 18.15 lbs, with carton dimensions given as 7.25 x 6.25 x 6 inches. Worth knowing if you are staging several boxes for a lift or figuring freight on a bulk fastener order.
