Metallics JMBHC620PL – Frequently Asked Questions
1) What size and grade is the Metallics JMBHC620PL hex bolt?
It's an M6 x 20 mm hex head bolt in property class 10.9, plain steel finish, with the part number JMBHC620PL. M6 means a 6 mm nominal thread diameter and 20 mm is the shank length under the head. Class 10.9 is the high-strength metric grade, roughly the metric counterpart to SAE Grade 8 in inch fasteners.
2) Is the plain steel finish on these M6 bolts OK for outdoor or damp locations?
No. These are plain steel with no plating or coating, so they will rust in wet, humid, or outdoor exposure. Use them for indoor, dry work (panel and enclosure assembly, strut and bracket fastening inside a building). For anything exposed to weather or washdown, go with a zinc plated or stainless M6 x 20 instead.
3) How many M6 x 20 bolts come in the JMBHC620PL jar?
100 bolts per jar. Metallics packs this one in a jar rather than a box, which is the shop-bin pack for a contractor's truck or a maintenance crib.
4) What thread pitch do M6 bolts use, and what nut and washer do I need?
Standard M6 coarse thread is 1.0 mm pitch, so these mate with any M6 x 1.0 nut or tapped M6 hole. For a class 10.9 bolt, pair it with a class 10 nut so the nut isn't the weak point, and use a hardened washer under the head if you're torquing to the grade's capacity. Nuts and washers are not included in the jar of 100.
5) Can I substitute a class 8.8 M6 x 20 bolt for this 10.9?
Going down to 8.8 drops the tensile strength, so if the drawing or equipment spec calls for 10.9 don't swap it. The other direction is usually fine: a 10.9 can stand in where an 8.8 was specified at the same M6 x 20 size, as long as the plain steel finish suits the environment. Watch the mating nut grade when you substitute up.
