Metallics JG5HTB59 – Frequently Asked Questions

1) Is the Metallics JG5HTB59 hex tap bolt threaded all the way to the head?
Yes. A hex tap bolt is fully threaded from the head to the point, which is what separates it from a hex cap screw with a plain shank. The JG5HTB59 is a 3/8-16 x 1-1/4 size with 16 threads per inch, right hand thread, cut to ASME B18.2.1-2012. Full threading is why these are used for bolting a motor base down to a tapped machinery frame, where the threads need to engage right up under the head.
2) Will a 3/8-16 bolt thread into a 3/8-16 tapped hole in a motor base, or do I need a coarse versus fine check?
3/8-16 is the standard coarse (UNC) pitch for a 3/8 inch diameter, so it mates with any 3/8-16 tapped hole or standard 3/8-16 nut. The shank measures 0.3690 to 0.3750 inch outside diameter and the thread is right hand. If the hole in your frame is 3/8-24, that is the fine pitch and this bolt will not run in.
3) Is Grade 5 strong enough for bolting down a motor, or should I step up to Grade 8?
Grade 5 covers most equipment mounting work. These are medium carbon steel, heat treated, with 105,000 psi minimum tensile and a hardness of Rockwell C19-30. That is the normal choice for motor bases, machinery brackets, and automotive or truck repair. Step up to a Grade 8 fastener only where the engineer's spec calls for the higher proof load, such as high-cycle shock or structural connections.
4) Is the zinc plating on these bolts good enough for outdoor or damp locations?
The finish is zinc plating over steel, which is a mild corrosion coating meant for indoor and protected use. It holds up in a mechanical room, a plant interior, or inside an enclosure. For sustained outdoor exposure, washdown areas, or anywhere near salt, specify hot dip galvanized or 18-8 stainless in the same 3/8-16 x 1-1/4 size instead.
5) How many bolts come in a jar, and can I buy fewer than 100?
JG5HTB59 ships as a jar of 100 bolts, and 100 count is the order minimum, so the jar is the smallest buying unit. The packed jar weighs 2,177 g. Other sizes and quantities in the same Grade 5 hex tap bolt series are available by request.
6) Do these Metallics hex tap bolts meet Buy American requirements on a federal job?
The JG5HTB59 is flagged compliant for both ARRA and Buy American in the product record, while country of origin is listed as China. If your contract rides on a domestic melt-and-manufacture clause rather than the ARRA compliance flag, confirm which standard the specification is written to before you commit the fasteners.
7) What steel are these Grade 5 hex tap bolts actually made from?
Material is carbon steel in the AISI 1008 to 1026 range, heat treated to Grade 5 properties: 105,000 psi minimum tensile, 105,000 psi minimum yield, Rockwell C19-30. Nothing about that is weldable-spec material, so treat them as mechanical fasteners and do not tack weld them in place.
