Metallics JMBHC620 – Frequently Asked Questions
1) What thread size and length is the Metallics JMBHC620 hex bolt?
It's an M6 metric hex bolt with a 20mm length, made to DIN 931. DIN 931 is the partially threaded hex cap screw standard, so expect a plain shank under the head rather than thread running the full length. Mate it with M6 x 1.0 nuts and tapped holes.
2) How strong is the Metallics JMBHC620 bolt, and is it strong enough for structural bracket mounting?
Rated at 120,350 psi minimum tensile and 95,700 psi minimum yield, with a hardness of Rockwell C23-34. That strength level is in line with a medium carbon alloy metric class bolt and is well above commercial grade mild steel fastenings, so it's suitable for machinery, strut, bracket and equipment anchoring. For anything that is engineered structural steel connection work, follow the engineer's specified bolt class on the drawing.
3) How many bolts come in a jar of Metallics JMBHC620?
100 pieces per jar, and the jar is the order minimum, so 100 count is the smallest quantity sold. The filled jar weighs 612 g. Metallics also offers other sizes and quantities in the MBHC and JMBHC series by request.
4) Can these M6 bolts be used outdoors or in damp locations?
The bolt is zinc plated steel. Zinc plating handles indoor and sheltered use, interior electrical enclosures, strut, and equipment mounting without issue. For sustained outdoor exposure, washdown, or coastal air, step up to hot dip galvanized or stainless; plated zinc will eventually show white corrosion in those conditions.
5) What wrench or socket size fits the head on this M6 hex bolt?
The head is a standard hex. On DIN 931 M6 hardware the across flats dimension is 10mm, so a 10mm socket or wrench drives it. The head height falls in the 3.85 to 4.15 range, which matters if you're torquing in a tight recess or under a cover plate.
6) Do these bolts meet Buy American or ARRA requirements on a federal job?
The JMBHC620 carries a Buy American compliant and ARRA compliant designation in the product record, while country of origin is listed as China. On federally funded work, give both facts to your compliance reviewer before submitting, since fastener provisions vary by contract.
7) Are nuts and washers included with the Metallics JMBHC620 jar?
The jar contains 100 hex bolts only. M6 hex nuts, flat washers, and lock washers are separate line items, so add them to the order if the connection isn't going into a tapped hole or a channel nut.
8) Is the JMBHC620 the same bolt as the Metallics MBHC620?
Same bolt, different pack. The series covers both MBHC and JMBHC designations; the J prefix is the jar pack of 100. If you want a different quantity of the same M6 x 20 zinc plated hex bolt, that's a packaging change, not a different fastener.
