Metallics JMHTB512 – Frequently Asked Questions

1) Is the Metallics JMHTB512 M5 bolt threaded all the way to the head?
Yes. The JMHTB512 is a tap bolt, so the thread runs the full length of the shank right up to underneath the hex head. That matters when you are bolting through a thick flange or shimming a motor base, since there is no unthreaded grip length limiting how deep the nut or tapped hole can engage. There is also a washer face under the head, so it seats flat without a separate flat washer.
2) What thread pitch is the M5 x 12 Metallics tap bolt, and will it thread into a standard M5 tapped hole?
Pitch is 0.8 mm, right hand, which is the standard coarse pitch for M5. It will thread into any M5 x 0.8 tapped hole or standard M5 nut. If your equipment uses an M5 fine pitch, this is not the bolt for it.
3) What does Class 8.8 mean on these M5 bolts, and is it strong enough for mounting a motor?
Class 8.8 is a medium carbon steel bolt that has been heat treated, which is why these are used for bolting motors to machinery and in automotive and truck repair. Hardness is Rockwell C22-32, with a stated minimum yield strength of 92,800 psi and minimum tensile of 11,600 psi. For general equipment mounting at M5 that is a structural-duty fastener rather than a hardware-store grade bolt.
4) Do these Metallics M5 bolts meet Buy American or ARRA requirements for a government or institutional job?
No. The JMHTB512 is not Buy American compliant and is not ARRA compliant, with multiple countries of origin. If your contract carries a domestic-sourcing clause, this jar will not satisfy it and you need a domestically produced fastener.
5) How many bolts come in a jar of Metallics JMHTB512, and can I buy fewer?
The JMHTB512 ships as a jar of 100, and the jar is the order minimum, so 100 pieces is the smallest quantity. The jar packaging is the reason these end up on service trucks and in shop drawers rather than loose in a bin. Metallics does list other sizes and quantities in the MHTB and JMHTB series by request.
6) What size wrench or socket do I need for the Metallics M5 x 12 hex tap bolt?
It is a hex head bolt with a head width in the 7.78 to 8 range and head height 3.35 to 3.65, which puts it on an 8 mm socket or wrench. Nominal shank is M5 with a 12 mm length under the head.
7) How much does a jar of 100 Metallics M5 x 12 hex tap bolts weigh?
The jar of 100 comes in at 345 g, about 12 ounces, so it is an easy add to a van stock order or a tool bag.
