Metallics JMHTB6101 Bolts M6 x 10 10.9 Hx Tap Blt St-zn (Jar 100)

Yes. It's a hex head tap bolt, meaning the thread runs the full length of the shank right up under the washer face beneath the head. With a 10mm length there is no unthreaded grip, so it works where you need thread engagement through a thin bracket or strut and into a tapped hole or nut without any shoulder getting in the way.

The thread is M6 with a 1mm pitch, right hand, which is the standard coarse metric M6 thread. Any standard M6 x 1 nut or tapped M6 hole will take it.

Class 10.9 is the higher strength option. This Metallics bolt is heat treated alloy steel rated at 150,800 psi minimum tensile and 136,300 psi minimum yield, hardness Rockwell C32-39. You go to 10.9 over 8.8 where the joint is more highly loaded, as in automotive and fleet work. For general electrical, plumbing, or HVAC mounting, an 8.8 bolt is usually enough, so spec 10.9 when the drawing calls it out or the clamp load demands it.

It ships as a jar of 100 pieces, and 100 in a jar is the order minimum. Jar weight is listed at 454 g. Other sizes and quantities in the MHTB and JMHTB series can be requested if you need a different count or length.

The finish here is zinc plated steel, which is a mild indoor corrosion coating. It's fine for interior electrical, plumbing, heating, and air conditioning work, equipment rooms, and enclosures. For sustained outdoor exposure, washdown areas, or coastal sites, go to stainless or hot dip galvanized instead; plated zinc will eventually rust through in those conditions.

No. The JMHTB6101 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 fastener won't satisfy them.

Not for bearing against a flat steel surface. The hex head is formed with a washer face underneath it, which spreads the load and gives a clean seat. You'd still add a flat washer over a slotted strut, soft material, or an oversized hole, and a lock washer or thread locker where vibration is a concern.
