Metallics JMHTB10201 Bolts M10 x 20 C10.9 Hx Tap Blt St-zn (Jar 100)

Yes. The JMHTB10201 is a hex tap bolt, meaning the thread on the 20mm shank runs all the way to directly beneath the head. That is the difference between a tap bolt and a partially threaded hex cap screw: with a short 20mm length you get full thread engagement in a tapped hole or a thin bolted joint, with no unthreaded grip length eating up your usable depth.

Thread pitch is 1.5mm, right hand, which is standard M10 coarse. It will mate with any coarse M10 x 1.5 tapped hole or nut. It will not thread into an M10 fine (1.25mm) hole, so check the pitch on the component you are bolting into before you crack the jar open.

Strength. The class 10.9 rating carries 150,800 psi minimum tensile and 136,300 psi minimum yield, with a hardness of Rockwell C32-39. Metallics calls this out for automotive and fleet use where an 8.8 fastener does not have the tensile capacity for the joint. If a drawing or service manual specifies 10.9, substituting 8.8 is not a like-for-like swap.

The head is a hex with a washer face underneath it, and the published head width across flats runs 16.73 to 17, so a 17mm socket or wrench is the fit. The washer face bears on the mating surface, so you do not strictly need a flat washer under the head on a clean machined face.

The JMHTB10201 is high alloy heat-treated steel with a zinc finish. Zinc plating is a sacrificial coating that handles indoor, enclosure, and general equipment duty well, but it is not stainless. For sustained wet exposure, washdown, or coastal air you should expect corrosion over time and specify a stainless or hot-dip galvanized fastener instead. Note also that high strength class 10.9 steel is the grade to use where tensile load matters, which stainless typically will not match.

These ship 100 pieces to a jar, and 100 count is the order minimum, so the jar is the smallest unit. The jar weighs 2209 g filled. Metallics does list other sizes and quantities on request within the MHTB and JMHTB series if M10 x 20 is not the length you need.

The JMHTB10201 is flagged ARRA compliant and Buy American compliant in the manufacturer data, with country of origin China. If your contract runs a strict domestic-melt-and-manufacture clause rather than the ARRA-style provision, verify which standard your spec actually invokes before you submit it.
