Metallics JCB22SS – Frequently Asked Questions
1) What thread size and pitch are the Metallics JCB22SS carriage bolts?
5/16-18 UNC, so 18 threads per inch on a coarse Unified thread cut to ANSI/ASME B1.1. They take any standard 5/16-18 nut, and the shank measures 0.307 to 0.324 inch across with a 3 inch length.
2) Will stainless carriage bolts like the JCB22SS corrode outdoors or on a rooftop run?
They are 18-8 stainless steel to ASTM F593, which is the standard austenitic stainless fastener spec used for wet, exterior, and corrosive-atmosphere work. That makes them a reasonable choice for rooftop strut, outdoor enclosures, and damp mechanical rooms where plated carbon steel would rust out.
3) What size hole do I need to drill for a 5/16-18 x 3 carriage bolt?
Size the hole to the bolt's outside diameter, listed at 0.272 to 0.324 inch, so a 5/16 inch (0.3125) hole is the normal drill and 11/32 gives a clearance fit. The square shoulder under the head has to bite the material to keep the bolt from spinning, so a hole drilled oversize in metal will need the nut held with a wrench instead.
4) Do these stainless carriage bolts qualify for a federally funded job with Buy American requirements?
Metallics lists the JCB22SS as both Buy American compliant and ARRA compliant, which is what a public agency or institutional procurement file usually needs on record. Country of origin is listed as multiple, so if your contract requires a single named origin on the certification, specify that at the time of order.
5) Is the head on the Metallics JCB22SS a hex head or a round carriage bolt head?
The head is called out as hex, measuring 0.688 to 0.719 inch across and 0.156 to 0.176 inch high, built to ASME B18.5 dimensions. If you are expecting the smooth domed head of a classic round-head carriage bolt, confirm that a hex profile works for your application before you order.
6) How many bolts come in a jar of JCB22SS, and can I buy fewer?
They ship 100 to a jar, and 100 count is the order minimum, so the jar is the smallest unit. Metallics notes other sizes and quantities are available by request if 5/16-18 x 3 isn't the length you need.
7) What is the exact part number to order these Metallics stainless carriage bolts?
Order Metallics JCB22SS, the 5/16-18 x 3 stainless carriage bolt in the CB and JCB series. The JCB prefix is the jar-packed line.
