Metallics JG5HTB14 – Frequently Asked Questions
1) Is the JG5HTB14 threaded all the way to the head?
Yes. A hex tap bolt is fully threaded for its entire 2 inch length, which is what separates it from a standard hex cap screw with a plain shank. That matters when you are bolting into a tapped hole in a motor foot or a machine frame, because you can run the bolt down to whatever depth the tapped hole allows without a grip section bottoming out.
2) Will a 5/16-18 hex tap bolt thread into a standard 5/16 coarse tapped hole?
Yes. 18 threads per inch is 5/16-18 UNC, the standard coarse pitch for a 5/16 fastener, and the thread is right hand. Outside diameter runs 0.3065 to 0.3125 inch and the thread conforms to ASME B18.2.1-2012, so it mates with any 5/16-18 tapped hole or nut. It will not fit a 5/16-24 fine thread hole.
3) How strong is a Grade 5 bolt, and is it enough for mounting a motor?
Grade 5 here means medium carbon steel, heat treated, with 105,000 psi minimum tensile and 105,000 psi minimum yield and a hardness of Rockwell C19-30. That is the normal structural and machinery grade for mounting motors to equipment and for automotive and truck repair work. If your drawing calls out Grade 8 or a metric class 10.9, this is not a substitute.
4) What size wrench or socket do I need for the Metallics JG5HTB14 5/16-18 hex tap bolt?
The hex head measures 0.489 to 0.500 inch across the flats, so a 1/2 inch wrench or socket is the right tool. Head height is 13/64 inch, with a wrenching height of 0.14 inch, so you need about that much clear flat under the socket to get full engagement on the flats.
5) Is a zinc plated steel hex tap bolt OK outdoors or in a damp mechanical room?
The bolt is steel with a zinc finish, made from AISI 1008-1026 material. Zinc plating handles indoor and sheltered damp conditions, which covers most motor mounts, panels, and equipment rooms. For direct weather exposure, washdown, or coastal work, step up to a stainless 18-8 hex tap bolt instead, since zinc plating will eventually corrode through.
6) How many bolts come in a jar of Metallics JG5HTB14 and can I buy fewer?
They ship as a jar of 100, and 100 count is the order minimum, so the jar is the smallest buy. The filled jar weighs 2059 g. Other sizes and quantities in the G5HTB and JG5HTB series are available by request.
7) Do nuts or washers come with the Metallics JG5HTB14 jar?
Bolts only, 100 to the jar. No nuts or washers are included. If you are bolting through rather than into a tapped hole, order 5/16-18 hex nuts and 5/16 flat and lock washers separately.
8) Does this bolt meet Buy American or ARRA requirements for a public project?
The JG5HTB14 is flagged compliant for both ARRA and Buy American, with country of origin China. Submit it against your project's specific domestic content language, since compliance programs differ in how they treat origin.
