Metallics JCB24SS – Frequently Asked Questions
1) Is the JCB24SS carriage bolt stainless steel, and will it hold up outdoors?
It is 18-8 stainless steel, made to ASTM F593. 18-8 is the standard austenitic grade used for outdoor and damp-location work such as strut, conduit racks, and rooftop equipment supports. For saltwater or chloride-heavy exposure, 316 stainless is the step up.
2) What hole size do I need to drill for a 3/8 carriage bolt like the JCB24SS?
Shank measures 0.368 to 0.388 inch across, so a 7/16 inch hole clears it with room to pull the square neck through. The square neck under the mushroom head is what keeps the bolt from spinning once it is drawn into wood or a slotted channel, so the hole should be a clearance hole, not a tight one.
3) Does the JCB24SS carriage bolt meet Buy American or ARRA requirements?
No. The JCB24SS is not Buy American compliant and is not ARRA compliant, and country of origin is listed as multiple. If your project carries a domestic-sourcing clause, this is not the bolt for it.
4) How big is the head on the Metallics JCB24SS, and will it sit flush?
Head width runs 0.782 to 0.844 inch with a head height of 0.188 to 0.208 inch. That is a low, domed mushroom head that sits proud but smooth, with no wrench flats, so there is nothing to snag and nothing to grip from the head side. You tighten from the nut end only.
5) How many bolts come in a jar of Metallics JCB24SS?
They ship 50 to a jar, and 50 each is the order minimum. The jar pack is what makes this practical for a truck or a shop shelf rather than loose bulk.
6) What standard are these carriage bolts dimensioned to?
Dimensions follow ASME B18.5, the round head bolt standard, with threads to ANSI/ASME B1.1 and material to ASTM F593. If your spec sheet calls out B18.5 round head square neck bolts in 18-8 stainless, the JCB24SS matches that callout.
