Metallics JMHTB830 Bolts M8 X 30 C8.8 Hx Tap Blt St-zn (Jar 100)

Fully threaded. The JMHTB830 is a hex tap bolt, so the threads run the full length of the shank right up to directly beneath the head, which has a washer face under it. That matters when you are bolting into a tapped hole or blind hole and need thread engagement at the very top of the grip.

Yes. It is an M8 by 30 mm bolt with a 1.25 mm thread pitch, which is the standard coarse metric pitch for M8, and the thread is right hand. It will thread into any M8 x 1.25 tapped hole or nut. It will not work in a fine pitch M8 x 1.0 hole.

No. The JMHTB830 is not Buy American compliant and is not ARRA compliant, and country of origin is listed as multiple. If your job carries domestic sourcing language, this fastener will not satisfy it.

They ship as a jar of 100 pieces, and the jar is the minimum order unit. Metallics notes other sizes and quantities are available by request, so if you need a different length or pack count in the MHTB/JMHTB tap bolt family it can be sourced.

The finish is zinc plating over steel, which is a general purpose corrosion coating suited to indoor and protected mechanical work, the electrical, plumbing, heating and air conditioning applications Metallics lists for it. For continuous outdoor exposure, washdown, or coastal conditions, step up to a hot dip galvanized or stainless fastener instead.

It is a hex head bolt, so a standard socket or open end wrench drives it. The head carries an integral washer face underneath, which spreads load against the mating surface, but that is not a substitute for a flat washer on soft or slotted material. Nuts, flat washers and lock washers are not included in the jar, so order them separately if the joint is a through bolt rather than a tapped hole.
