Metallics JMHTB6601 Bolts M6 x 60 C10.9 Hx Tap Blt St-zn (Jar 100)

It's an M6 by 60mm hex tap bolt with a 1.0mm thread pitch, right-hand thread. That's the standard coarse metric pitch for M6, so it runs into any M6 x 1.0 nut or tapped hole. Because it's a tap bolt, the thread runs the full length of the shank right up under the head, so there's no unthreaded grip section to work around on thin or stacked material.

No. The JMHTB6601 M6 x 60 tap bolt is manufactured in China and is flagged as non-compliant for both Buy American and ARRA sourcing requirements. If you're procuring for a federally funded job with domestic-content language, this one won't satisfy it.

They ship as a jar of 100, and 100 count is the order minimum, so the jar is the smallest unit you can take. Total weight of the packed jar is 1483 g. Metallics also makes other sizes and quantities in the MHTB and JMHTB tap bolt series available by request if M6 x 60 isn't the size you need.

The finish is zinc plating over steel, which is a mild corrosion barrier suited to indoor, sheltered, and general shop or fleet-bay conditions. It is not a marine or continuously wet-service coating. For washdown or exterior exposure, plan on a stainless or hot dip galvanized fastener instead, keeping in mind stainless will not give you 10.9-level tensile.

Not for bearing surface reasons. The JMHTB6601 is a hex head bolt with a washer face machined beneath the head, so it already presents a clean, flat bearing surface against the part. Add a hardened flat washer only if you're clamping soft material, an oversized hole, or a slot, where the load needs spreading.

Yes, within the load you're designing to. These are stocked as electrical supply fasteners and the full-length thread suits strut channel nuts, enclosure feet, and bracket stacks where you need thread engagement anywhere along the 60mm shank. At class 10.9 with 150,800 psi minimum tensile they're well above ordinary commercial-grade hardware for that work.
