Metallics JMHTB1060 – Frequently Asked Questions
1) What thread size and pitch is the Metallics JMHTB1060 hex tap bolt?
It's an M10 x 60mm hex tap bolt with a 1.5mm thread pitch, right hand thread. That 1.5 pitch is the standard metric coarse pitch for M10, so it mates with ordinary M10 coarse nuts and tapped M10 holes. Shank length is 60mm.
2) Is the M10 x 60 Metallics tap bolt threaded all the way to the head?
Yes. The threads run the full length of the shank right up to directly beneath the head, which is what makes it a tap bolt rather than a partially threaded hex cap screw. Useful when you're bolting into a tapped hole and need engagement anywhere along the 60mm.
3) How strong is a Class 8.8 M10 bolt, and what is it rated for?
Grade 8.8 medium carbon steel, heat treated: 120,350 psi minimum tensile and 95,700 psi minimum yield, hardness Rockwell C23-34. That's the metric equivalent class to SAE Grade 5 in inch sizes, and it's the usual choice for machinery and equipment mounting rather than light sheet-metal work.
4) Are Metallics JMHTB1060 bolts Buy American or ARRA compliant?
No. The M10 x 60 Class 8.8 hex tap bolt is not Buy American compliant and is not ARRA compliant, with multiple countries of origin. If your project carries domestic sourcing requirements, this part won't satisfy them.
5) Do I need a washer under the head of this hex tap bolt?
The head has an integral washer face beneath it, so it bears cleanly on a flat machined surface without a separate washer. On softer material, slotted holes, or oversized holes you'd still add a flat washer to spread the load.
6) How many bolts come in a jar of Metallics JMHTB1060?
50 pieces per jar, and 50 each is the order minimum. The jar pack is the J prefix in the part number; the series covers both MHTB bulk and JMHTB jarred packaging.
7) Is a zinc plated M10 bolt okay for outdoor or damp locations?
The finish is zinc plating over steel, which handles indoor and normally dry mechanical-room conditions. For sustained wet exposure, coastal air, or direct weather, zinc plated carbon steel will eventually corrode and hot-dip galvanized or stainless is the better call.
8) What wrench size fits the head on this M10 Class 8.8 tap bolt?
Metallics lists the head across flats at 16.73 to 17 and across corners at 17.77, so a 17mm socket or wrench is the fit. Shank outside diameter runs 9.78 to 10, consistent with a nominal M10.
9) What are these M10 hex tap bolts typically used for on a job?
The common use is mounting motors to machinery, and they're also a staple in automotive and truck repair. Metallics lists them for electrical, plumbing, heating and air conditioning work, so they cover equipment anchoring, pump and blower bases, and bracket fastening into tapped holes.
10) How tall is the hex head, and will it clear a counterbore or tight bracket?
Head height is listed at 6.22 to 6.58, so allow at least 6.6 plus socket wall for clearance above the bearing surface. In a recessed pocket, measure the counterbore depth against that figure before you commit.
