Metallics JMHTB10301 Bolts M10 x 30 C10.9 Hx Tap Blt St-zn (Jar 50)

Yes. It's a tap bolt, so the thread runs the full 30mm length right up to underneath the hex head, with no unthreaded shank. That matters when you're bolting through thicker material or into a tapped hole and need thread engagement over the whole grip.

The thread pitch is 1.5mm, right-hand, which is the coarse M10 standard. Any standard coarse M10 nut or M10 x 1.5 tapped hole will take it. If your hole is M10 x 1.25 fine thread, this bolt won't thread in.

Class 10.9 is the higher-strength grade. These Metallics tap bolts carry a 150,800 psi minimum tensile and 136,300 psi minimum yield, with a Rockwell C32-39 hardness from heat treatment. The description points to automotive and fleet work where a class 8.8 fastener doesn't give enough tensile strength. If your print calls out 8.8, a 10.9 exceeds it, but don't substitute downward.

Head width across flats runs 16.73 to 17mm, so a 17mm socket or wrench is what you want on it. There's also a washer face under the head, which seats against the work surface and spreads load slightly without a separate flat washer.

The finish is zinc over steel, which is a general-purpose coating for dry indoor and sheltered use. It gives moderate corrosion resistance but it isn't a marine or sustained-wet-exposure plating. For a roof, exterior, or washdown area, specify a hot-dip galvanized or stainless fastener instead.

They ship as a jar of 50, and 50 pieces is the order minimum, so it's a full-jar purchase. The jar weighs 1,361 g. Other sizes and quantities are available by request.

Country of origin is China, and the record carries a Buy American and ARRA compliance flag of C. If you're bidding a federally funded project with a domestic-sourcing clause, verify the flag against your contract's specific requirement before you submit, since the origin is imported.
