Metallics JMHTB612 – Frequently Asked Questions
1) What size is the Metallics JMHTB612 hex tap bolt, and is it fully threaded?
It's an M6 bolt with a 12mm length under the head, and the thread runs all the way up to directly beneath the head, so there is no unthreaded shank to work around in a shallow tapped hole. The thread pitch is 1mm (standard M6 coarse) and it is right-hand thread.
2) Is a Class 8.8 zinc bolt strong enough for mounting a motor to a frame?
Yes, that's the intended use. The JMHTB612 is medium carbon steel, heat treated to property class 8.8 with a hardness of Rockwell C22-32, and the described application is mounting motors to machinery as well as automotive and truck repair. The zinc plating gives general indoor corrosion protection, not marine or outdoor exposure performance.
3) Are Metallics JMHTB612 bolts Buy American or ARRA compliant for a government job?
No. These hex tap bolts are not Buy American compliant and are not ARRA compliant, with multiple countries of origin. If your contract carries a domestic sourcing clause, this is not the fastener to specify.
4) How are these M6 hex tap bolts packaged and what is the minimum order?
They ship in a jar of 100 pieces, and the jar is the minimum order unit, so 100 is the smallest quantity. The filled jar weighs 463 g. For an MRO crib stocking common metric sizes, that's a shelf-ready container rather than a loose bulk bag.
5) Do these Metallics hex tap bolts have a washer face under the head?
Yes. There is a washer face beneath the hex head, which spreads the bearing load slightly and gives a cleaner seat on the mating surface. It does not replace a flat washer on soft or slotted material, so add one where the hole is oversized.
6) What trades use the Metallics MHTB and JMHTB metric tap bolts?
The MHTB and JMHTB series is stocked for electrical, plumbing, heating and air conditioning work, plus motor mounting on machinery and automotive or truck repair. Typical jobs are bolting a motor, blower or pump into a tapped base where the equipment is metric rather than inch.
7) Can I get this Metallics hex tap bolt in other metric lengths or pack sizes?
Other sizes and quantities in the MHTB and JMHTB hex tap bolt line are available by request. The catalogued item here is the M6 x 12 zinc plated class 8.8 bolt in a 100 piece jar.
