Metallics JMHTB540 – Frequently Asked Questions

1) What size and thread pitch is the Metallics JMHTB540 hex tap bolt?
It's an M5 bolt with a 40mm length and a 0.8mm thread pitch, which is the standard coarse metric pitch for M5. Threads are right hand and run the full length of the shank up to the washer face under the hex head, so you can clamp any grip length up to the 40mm shank.
2) Is a class 8.8 M5 bolt strong enough to bolt a motor to a frame?
Yes, that's the intended use. The JMHTB540 is a class 8.8 medium carbon steel bolt, heat treated, with a minimum tensile strength of 120,350 psi and a minimum yield of 95,700 psi, hardness Rockwell C23-34. Class 8.8 is the common metric structural/machine grade, and the description calls out mounting motors to machinery along with automotive and truck repair.
3) Is the Metallics JMHTB540 bolt Buy American or ARRA compliant for a government job?
No. The JMHTB540 is not Buy American compliant and is not ARRA compliant, and country of origin is listed as multiple. If your specification carries a domestic sourcing requirement, this bolt will not satisfy it.
4) How many bolts come in a jar of Metallics JMHTB540, and can I buy less?
The JMHTB540 ships as a jar of 100 pieces, and one jar is the minimum order. The packed jar weighs 649 g. If you need a different size or a different pack count, Metallics offers other sizes and quantities in the MHTB and JMHTB series by request.
5) What is the difference between a hex tap bolt and a standard hex cap screw?
A tap bolt is threaded all the way to the head instead of having a plain shoulder under it. That matters when you are threading into a tapped hole or a nut close to the surface and need engagement right at the top of the shank. The JMHTB540 is that style: hex head with a washer face beneath it, fully threaded M5 x 40.
6) Will zinc plated steel bolts hold up for HVAC and electrical equipment mounting indoors?
Zinc plated carbon steel is the normal choice for indoor and protected mechanical mounting, and this is what the JMHTB540 carries: steel body, zinc finish. Metallics lists it for the electrical, plumbing, heating and air conditioning trades. For continuous wet exposure or coastal outdoor work, step up to stainless instead of zinc plating.
7) What wrench size do I need for an M5 class 8.8 hex bolt, and do I need washers?
An M5 hex bolt of this type takes an 8mm wrench or socket across the flats. The head has an integral washer face underneath, so against a flat machined surface you do not need a flat washer for bearing; add one only where the material is soft or the hole is oversized. Nuts and washers are not included in the jar of 100.
