Metallics JMBHC40 – Frequently Asked Questions
1) What thread size and length is the Metallics JMBHC40 hex bolt?
The JMBHC40 is an M4 metric hex head bolt with a 16mm length, made to DIN 931. DIN 931 is the partially threaded hex bolt standard, so the shank has an unthreaded portion under the head rather than thread running the full length. If your application needs thread all the way to the head, DIN 931 is the wrong profile for it.
2) How strong is the Metallics M4 hex bolt, and can I use it on a structural connection?
Published strength is 116,000 psi minimum tensile and 92,800 psi minimum yield, with a case hardness of Rockwell C22-32. That is a medium carbon strength class suited to equipment mounting, enclosure and device fastening. It is not a structural steel connection bolt, and anything on a stamped drawing calling for a specific structural grade should be bought to that grade.
3) How many bolts come in a jar of Metallics JMBHC40?
100 pieces per jar, and 100 is also the order minimum, so one jar is the smallest buy. The jar packaging is the reason to pick the JMBHC prefix over the bulk MBHC version of the same bolt, it keeps loose metric hardware sorted on a service truck or in a shop bin.
4) Is a zinc plated steel M4 bolt OK for outdoor or damp electrical work?
These are carbon steel with a zinc finish. Zinc plating handles indoor and dry enclosure duty well, but it is a sacrificial coating, not stainless. For wet locations, exterior strut, or washdown areas, specify a stainless M4 hex bolt instead of the zinc plated JMBHC40.
5) Does the Metallics JMBHC40 bolt meet Buy American and ARRA requirements on a federal job?
Metallics lists the JMBHC40 as both ARRA compliant and Buy American compliant, with China as the country of origin. On federally funded work, hand those two compliance flags plus the origin to your spec reviewer, since the applicable clause on your contract decides what is acceptable.
6) What size wrench or socket do I need for these M4 hex bolts?
The JMBHC40 has a hex head, and for an M4 bolt built to DIN 931 the across-flats size is 7mm, so a 7mm socket or combination wrench drives it. Metric drivers only, there is no clean inch equivalent at this size.
7) Do nuts or washers come with the Metallics JMBHC40 jar?
No. The jar contains 100 M4 x 16 hex bolts only. Order matching M4 hex nuts and flat or lock washers separately if the joint is not a tapped hole.
8) What does a jar of 100 of these bolts weigh for shipping?
A full jar of the M4 x 16 zinc plated hex bolts is listed at 227 g, with the jar itself measuring 3 in long, 2.15 in high and 76.2 mm wide. Light enough to keep several sizes on the van without thinking about it.
9) Can I get this Metallics hex bolt in a different length or a larger quantity?
Yes. The MBHC and JMBHC series covers other metric diameters and lengths, and Metallics notes other sizes and quantities are available by request. The JMBHC prefix is the jar pack; ask for the bulk MBHC equivalent when you are consuming them by the thousand.
