Metallics JMHTB14501 – Frequently Asked Questions
1) What thread size and pitch are the Metallics JMHTB14501 hex bolts?
The JMHTB14501 is an M14 bolt with a 1.25 mm thread pitch, right hand thread, and a 50 mm length. That 1.25 pitch is the fine-thread M14, not the coarse 2.0, so it will not run into a standard coarse M14 nut or tapped hole. Check the tapped hole before ordering.
2) Is a class 10.9 bolt strong enough to replace an 8.8 bolt on fleet or equipment repair?
Yes. The JMHTB14501 is grade 10.9 with a minimum tensile strength of 150,800 psi and minimum yield of 136,300 psi, which is the step up from class 8.8 used where higher clamp load is needed. It is high alloy steel, heat treated to Rockwell C32-39. Going the other way, do not substitute an 8.8 where a 10.9 was specified.
3) Do these Metallics bolts meet Buy American or ARRA requirements for a government job?
No. The JMHTB14501 is not Buy American compliant and is not ARRA compliant, with multiple countries of origin on record. If your contract carries a domestic sourcing clause, this part will not satisfy it.
4) Are these M14 hex bolts fully threaded or do they have a shoulder?
Fully threaded. The threads on the JMHTB14501 run all the way up to directly beneath the hex head, and there is a washer face under the head. If your joint needs an unthreaded shank through the shear plane, this tap bolt is the wrong style.
5) Will zinc plated grade 10.9 bolts hold up outdoors?
The JMHTB14501 is steel with a zinc finish, which handles indoor and sheltered use and light weather exposure. For sustained wet, coastal, or chemical exposure a zinc plated alloy bolt is not the right pick, and high strength alloy fasteners are sensitive to corrosion driven cracking, so specify a fastener rated for that environment instead.
6) How are the Metallics M14 x 50 hex tap bolts packaged and what is the minimum order?
They ship in a jar of 50, and the order minimum is 50 each. Handy for a service truck or a shop bin rather than bulk box quantities. Metallics lists other sizes and quantities by request.
7) What head style is the JMHTB14501 and what drives it?
Hex head, driven with a wrench or socket, with a washer face underneath so it seats flat without a separate washer on a clean machined surface. Part of the Metallics MHTB and JMHTB hex tap bolt series.
