Metallics JMHTB6701 Bolts M6 x 70 C10.9 Hx Tap Blt St-zn (Jar 100)

It's an M6 bolt with a 1.0 mm thread pitch, right hand thread, in a 70 mm length. That's the standard coarse metric pitch for M6, so it mates with M6 x 1 nuts and tapped holes. Thread runs the full length of the shank up to the washer face under the head, which is what makes it a tap bolt rather than a partially threaded hex cap screw.

Yes. The JMHTB6701 is property class 10.9, rated at 150,800 psi minimum tensile and 136,300 psi minimum yield, hardness Rockwell C32-39. It's specified for automotive and fleet work where a class 8.8 fastener does not give enough tensile strength. If your drawing calls out 8.8 or a plain grade, a 10.9 will carry the load, but match the class your spec names rather than substituting upward on a torqued critical joint, since torque values differ by class.

Yes, full thread. The threads extend the entire shank to directly beneath the hex head, which carries a washer face. Fully threaded means you can set your grip length wherever you need it with nuts and washers, and it threads to the bottom of a tapped through-hole, which a partially threaded cap screw of the same 70 mm length cannot do.

They ship 100 pieces to a jar, and 100 is the order minimum, so one jar is the smallest buy. Jar packaging keeps loose metric fasteners sorted on a service truck or bench. Metallics lists other sizes and quantities in the MHTB and JMHTB series by request.

These are high alloy steel with a zinc plated finish, which is a mild indoor and sheltered-exposure coating. It handles shop, equipment, and interior mechanical use fine. For direct weather, roof curbs, or anything washed with chlorides, zinc plating on steel will corrode over time, and class 10.9 alloy steel is also susceptible to hydrogen embrittlement in aggressive environments, so a hot dip galvanized or stainless fastener is the better call there.

Metallics lists the JMHTB6701 as compliant for both ARRA and Buy American purposes. Country of origin is China. If your contract uses a strict domestic-melt or domestic-manufacture clause, verify against the clause text your agency wrote, because the origin and the compliance flag need to be read together on federally funded work.

The hex head measures 10 mm across the flats, so a 10 mm wrench or socket is what you want. That's the standard head size for M6 metric hex bolts, which matters if you're standardizing a tool kit around metric fleet work.
