Metallics G5HTB68 – Frequently Asked Questions
1) Is the Metallics G5HTB68 tap bolt threaded all the way to the head?
Yes. A hex tap bolt is fully threaded along its length, unlike a hex cap screw with a plain shank, so the G5HTB68 carries 5/8-11 right-hand thread over the full 3 inch length. That matters when you are threading into a tapped hole in a motor base or bracket and need engagement right up at the bearing surface.
2) What hole size do I need to drill and tap for these 5/8-11 bolts?
The bolt body runs 0.6170 to 0.6250 inch outside diameter on a 5/8-11 UNC thread, so a tapped hole takes a 17/32 inch tap drill followed by a 5/8-11 tap. For a through hole with a nut, a 11/16 inch clearance hole is the usual call. Thread conforms to ASME B18.2.1-2012.
3) Will the zinc plated finish hold up outdoors?
The finish is zinc plating over a steel bolt, which is built for indoor and sheltered use, light moisture, and general machinery mounting. For continuous wet exposure, coastal air, or washdown environments, go to an 18-8 stainless hex tap bolt in the same 5/8-11 x 3 size instead, since zinc plating sacrifices itself and will eventually rust through.
4) How many bolts come in a box of Metallics G5HTB68?
Fifty bolts per box, and 50 is the minimum order quantity. Metallics notes other sizes and quantities can be had on request, so if a job needs a different length in the same 5/8-11 thread it can be asked for.
5) Does the Metallics G5HTB68 tap bolt meet Buy American or ARRA requirements on a federal job?
Metallics lists the G5HTB68 as compliant for both ARRA and Buy American purposes. Country of origin on the bolt is China, so if your contract requires domestic melt and manufacture rather than the ARRA compliance flag, confirm which standard the specification is written to before you submit it.
6) What steel is the Metallics Grade 5 hex tap bolt made from?
Material conforms to AISI 1008-1026 carbon steel, heat treated to reach Grade 5 properties. That is the standard feedstock range for Grade 5 fasteners and it is why the bolt comes out at Rockwell C19-30 rather than the harder Grade 8 range.
7) How much does a box of 50 of these 5/8-11 x 3 tap bolts weigh?
A box runs 14.77 lbs, which is worth factoring if you are staging several boxes on a lift or carrying them up to a mechanical room.
