Metallics JMBHC45 – Frequently Asked Questions
1) What size and thread is the Metallics JMBHC45 hex bolt?
It's an M4 metric hex head bolt with a 20mm length, so it takes an M4 nut or an M4 tapped hole. Material is steel with a zinc finish, and it's sold 100 to a jar.
2) How strong is the Metallics M4 x 20 hex bolt?
Rated 120,350 psi minimum tensile and 95,700 psi minimum yield, with a hardness of Rockwell C23-34. Those figures line up with a medium carbon steel bolt rather than a soft low carbon fastener, so it will take real clamp load for machine screw and equipment mounting work. Don't substitute it where a drawing calls out a specific metric property class, because the class marking is what an inspector checks.
3) Do I have to buy a full jar of 100 of these M4 bolts?
Yes, the JMBHC45 ships as a 100 count jar and 100 is the minimum order quantity. The jar packaging weighs 268 g total, which makes it practical to throw on a service van or keep in a parts bin. Other sizes and quantities in the MBHC and JMBHC series can be sourced by request.
4) What's the difference between the Metallics MBHC and JMBHC part numbers for metric hex bolts?
Same bolt family, different packaging. The JMBHC prefix, as on JMBHC45, is the jar packed presentation, 100 pieces to a jar. If you want bulk box quantities of the same metric hex bolt rather than counted jars, you're looking at the MBHC side of the series.
5) Where are these Metallics metric hex bolts made?
Country of origin is China. If you're procuring for a project with domestic sourcing language on it, verify the requirement against the origin before you commit, since that's the detail that gets flagged on submittals for government and institutional work.
