Metallics JMHTB535 Bolts M5 x 35 C8.8 Hx Tap Blt St-zn (Jar 100)

It's an M5 x 35mm tap bolt with a 0.8mm thread pitch, which is standard metric coarse for M5. Threads are right hand and run the full length of the shank right up under the head, so there is no unthreaded grip section to deal with when you need thread engagement close to the surface.

Class 8.8 is a medium carbon steel bolt, heat treated, rated at 120,350 psi minimum tensile and 95,700 psi minimum yield, with a hardness of Rockwell C23-34. Metallics lists motor-to-machinery mounting as a primary use for these, along with automotive and truck repair work. For a structural steel connection you'd be looking at a different fastener class, but for equipment and motor mounting at M5 this is the usual grade.

No. The JMHTB535 is not Buy American compliant and is not ARRA compliant, with country of origin listed as multiple. On a federally funded job with domestic sourcing requirements you'll need a domestically produced fastener instead.

No. M5 x 0.8 is a metric thread and will not engage an inch-series tapped hole such as 10-24 or 1/4-20, and it will damage the threads if forced. The hole or nut has to be M5 metric. If the equipment you're fastening into is inch threaded, order the inch-series tap bolt in that size rather than this one.

A tap bolt is threaded the entire length of the shank, where a standard hex bolt leaves part of the shank unthreaded. The JMHTB535 is a full-thread hex tap bolt, so it suits tapped (threaded) holes where you want the threads biting from top to bottom, and short grip stacks where a partially threaded bolt would bottom its shoulder before clamping. It also has a washer face under the hex head, giving a flat bearing surface against the part.

The finish is zinc plating over a steel body. That handles indoor and normally dry service well, including the electrical, plumbing, heating and air conditioning work Metallics lists these for. For continuous wet exposure, coastal air, or direct ground contact, zinc plated carbon steel will corrode over time and stainless or hot dip galvanized hardware is the better call.

They ship in a jar of 100 pieces, and the jar is the order minimum, so 100 is the smallest quantity. The filled jar weighs 576 g. Metallics notes other sizes and quantities are available by request if 100 of the M5 x 35 isn't the count you need.

The JMHTB535 has a standard hex head, driven with a wrench or socket rather than a driver bit. M5 metric hex heads typically take an 8mm socket, so a metric set is what you want on the truck for these, not SAE.
