Metallics JMHTB10601 Bolts M10 x 60 C10.9 Hx Tap Blt St-zn (Jar 50)

It's an M10 bolt with a 1.5 mm thread pitch, right-hand thread, in a 60 mm length. That 1.5 pitch is the standard coarse metric pitch for M10, so it threads into any standard M10 coarse nut or tapped hole. Bolt diameter measures 9.78 to 10 mm.

Fully threaded. The threads run the whole 60 mm shank right up to directly beneath the hex head, which is what makes it a tap bolt rather than a partially threaded hex cap screw. If your joint needs an unthreaded grip length through a clearance hole, a fully threaded tap bolt is the wrong choice.

Class 10.9 is the higher-strength option: 150,800 psi minimum tensile and 136,300 psi minimum yield, hardness Rockwell C32-39, heat-treated alloy steel. It's used in automotive and fleet work where an 8.8 fastener does not carry enough tensile load. Pick 10.9 when the joint spec calls for it; for general structural or utility work an 8.8 is usually what's specified.

No. The JMHTB10601 is not Buy American compliant and is not ARRA compliant, with country of origin listed as multiple. If your contract carries domestic sourcing requirements, this fastener will not satisfy them.

The hex head measures 16.73 to 17 across the flats, so a 17 mm socket or wrench is the size to have on the truck. Head height runs 6.22 to 6.58. There's a washer face beneath the head, so it seats flat without a separate washer on a machined surface.

Fifty bolts, supplied in a jar, and 50 each is the order minimum. The jar packaging suits a shop bench or service truck where you're pulling fasteners one at a time rather than opening a bulk box.

The finish is zinc plating over steel, which handles indoor, enclosed, and sheltered exterior service. For constant wet exposure, salt spray, or direct weather, zinc plating is light protection and you'd want hot-dip galvanized or stainless instead. Note that high-strength 10.9 alloy steel is also sensitive to hydrogen embrittlement, so don't substitute an unknown re-plated fastener.

Yes. The MHTB and JMHTB series covers additional sizes and pack quantities by request; the JMHTB10601 is the M10 x 60 mm configuration in a 50-piece jar. The MHTB prefix is the same bolt in alternate packaging.
