Metallics JCB41SS – Frequently Asked Questions
1) What thread does the Metallics JCB41SS 5/16 carriage bolt have, and will it take a standard 5/16-18 nut?
It is a 5/16 coarse thread bolt at 18 threads per inch, UNC, made to ANSI/ASME B1.1. Any standard 5/16-18 UNC nut threads on. For an all stainless assembly, pair it with an 18-8 stainless 5/16-18 hex nut so you don't mix a plated carbon nut onto a stainless bolt.
2) What size hole do I need to drill for this 5/16 stainless carriage bolt?
The shank measures 0.307 to 0.324 inch, with an overall outside diameter range of 0.272 to 0.324 inch, so a 5/16 inch hole is tight and most installers step up to 11/32 inch for clearance through metal or a drilled 5/16 in wood where the square neck needs to bite.
3) Is the Metallics JCB41SS actually stainless, or just plated?
Solid 18-8 stainless steel, made to the ASTM F593 material standard for stainless bolts. Nothing plated about it, so it holds up in damp mechanical rooms, exterior strut runs, and wash-down areas without the rust bleed you get from zinc plated carbon steel.
4) How many carriage bolts come in the Metallics JCB41SS package?
They ship 100 to a jar, and 100 count is the order minimum, so this is a bin-stock item rather than a loose-count buy. The jar weighs about 1225 g filled, useful if you're planning a van or crib restock.
5) Does this 5/16 stainless carriage bolt meet Buy American and ARRA requirements for a federally funded job?
Metallics lists the JCB41SS as compliant for both Buy American and ARRA, which is what public-works and federally funded project submittals ask for. Country of origin is listed as multiple, so if your spec requires a single named origin on the cert, request documentation for the lot you receive.
6) Is the Metallics JCB41SS made to a recognized dimensional standard so it interchanges with other brands?
It is built to ASME B18.5, the dimensional standard for round head bolts, so head and neck geometry match any other B18.5 5/16 carriage bolt. Head bearing width runs 0.688 to 0.719 inch and head height 0.156 to 0.176 inch, which is what matters when the head has to seat in an existing counterbore or against a slotted channel.
7) Can I get this Metallics stainless carriage bolt in other lengths or a different pack quantity?
Yes. The CB and JCB series covers other sizes and quantities by request, so if you need a 1-1/2 or 2 inch length in the same 18-8 stainless, or a larger bulk count instead of the 100 count jar, it can be quoted.
