Metallics JMHTB616 – Frequently Asked Questions

1) Is the Metallics JMHTB616 M6 x 16 hex tap bolt threaded all the way to the head?
Yes, it is a tap bolt, so the thread runs the full 16mm length right up to the underside of the head. That matters when you are bolting into a tapped hole or a blind threaded boss, where a partially threaded bolt would bottom out on its shank grip before clamping. The head also has a washer face beneath it to seat cleanly on the mounting surface.
2) What does class 8.8 mean on a metric hex bolt, and is it strong enough for mounting a motor?
Class 8.8 is a medium carbon steel bolt, heat treated, which is the common structural grade for machinery mounting. On the Metallics M6 x 16 tap bolt it is backed by a stated hardness of Rockwell C22-32 and a yield strength of 92,800 psi minimum. Mounting motors to machinery is one of its listed uses, along with automotive and truck repair work.
3) Does the Metallics M6 hex tap bolt qualify for a Buy American or ARRA funded job?
No. The M6 x 16 class 8.8 hex tap bolt is not Buy American compliant and is not ARRA compliant, with country of origin listed as multiple. If your project carries domestic sourcing requirements, this bolt will not satisfy them and you need a documented domestic fastener instead.
4) What thread pitch does the M6 x 16 class 8.8 hex tap bolt have?
The pitch is 1mm, which is the standard coarse metric pitch for an M6 fastener, and the thread is right hand. So it mates with any M6 x 1 tapped hole or nut. Thread diameter measures 6mm at the top of the stated outside diameter range of 5.82 to 6 in the spec data.
5) Is the JMHTB616 hex tap bolt plated for corrosion resistance, or is it bare steel?
It is steel with a zinc finish. Zinc plating handles indoor and sheltered mechanical rooms, panel work, and general HVAC and plumbing equipment mounting. For sustained outdoor exposure, wet wells, or coastal sites, step up to stainless rather than relying on zinc plating.
6) How many bolts come in a jar of Metallics JMHTB616, and can I buy fewer?
It ships as a jar of 100 pieces, and 100 in a jar is the order minimum, so that is the smallest unit sold. The filled jar weighs 531 g. Metallics does make other sizes and quantities in the MHTB and JMHTB tap bolt series on request.
7) Can I use an M6 tap bolt with a nut, or does it have to go into a tapped hole?
Either works. Because the Metallics M6 x 16 is fully threaded to the head, it takes a standard M6 x 1 right hand nut through a drilled hole just as readily as it threads into a tapped hole. The washer face under the head gives a flat bearing surface on both setups.
8) What size wrench or socket do I need for the JMHTB616 hex head bolt?
It has a standard hex head, so a socket or open end wrench fits it directly, no drive bit needed. Head height is stated as 3.85 to 4.15 in the spec data, which is the dimension to check if you are torquing it down in a tight recess or under a motor foot.
