Metallics JMHTB6351 – Frequently Asked Questions

1) Is the Metallics JMHTB6351 an M6 x 1.0 coarse thread bolt?
Yes. The JMHTB6351 is an M6 metric hex tap bolt with a 1.0 mm thread pitch, which is the standard coarse pitch for M6, and the thread is right hand. It runs 35 mm long under the head. If your tapped hole or nut is a fine-pitch M6 x 0.75, this bolt will not thread into it.
2) Is this bolt threaded all the way to the head, or does it have a plain shank?
Fully threaded. On the JMHTB6351 the threads run the full length of the shank right up under the head, which is what makes it a tap bolt rather than a partially threaded hex cap screw. That matters when you are threading into a tapped hole or a strut nut and need engagement close to the surface. It also carries a washer face beneath the hex head.
3) What is the difference between a class 10.9 bolt and a class 8.8 bolt, and do I need 10.9 here?
Class 10.9 is the higher strength option. The JMHTB6351 is a heat treated alloy steel bolt rated at 150,800 psi minimum tensile and 136,300 psi minimum yield, with a hardness of Rockwell C32-39. You would specify 10.9 over 8.8 where the joint needs greater tensile capacity, typical of automotive and fleet work. For general electrical strut and equipment mounting, an 8.8 or a standard zinc machine bolt usually covers the load, but 10.9 is never a downgrade on strength.
4) Does the Metallics JMHTB6351 meet Buy American or ARRA requirements for a public project?
No. The JMHTB6351 is not Buy American compliant and is not ARRA compliant, and country of origin is listed as multiple. If your contract carries a domestic sourcing clause, this bolt will not satisfy it and you need a domestically produced fastener instead.
5) How many bolts come in a Metallics JMHTB6351 pack, and can I buy fewer?
They ship in a jar of 100 pieces, and 100 is the order minimum, so one jar is the smallest buy. Shop weight for the jar is 875 g. The MHTB and JMHTB series runs other sizes and pack quantities on request.
6) Will zinc plated steel hold up outdoors or in a damp mechanical room?
The JMHTB6351 is steel with a zinc finish, which is a general purpose plated coating suited to dry indoor and protected locations such as panel rooms, equipment skids, and HVAC and plumbing work. It is not a stainless or hot dip galvanized fastener, so for continuous wet exposure, roof mounted equipment, or coastal air you should move to stainless.
7) What size wrench or socket do I need for this M6 hex tap bolt?
It takes a 10 mm hex socket or wrench. The head on the JMHTB6351 measures 9.78 to 10 across the flats, which is the standard M6 head size, and head height runs 3.85 to 4.15.
