Metallics CB38 – Frequently Asked Questions
1) Do the Metallics CB38 carriage bolts come with nuts?
Yes, they ship bolt and nut together, 25 sets to a jar. The jar is the minimum order quantity, so you buy in 25-count increments. Thread is 1/2-13, 13 threads per inch coarse, so any standard 1/2-13 nut or washer will suit if you need extras.
2) Is the CB38 carriage bolt OK for outdoor or damp locations?
It is zinc plated steel, which handles covered exterior, damp indoor, and general utility work. Zinc plating is not a marine or continuously wet finish, though. For pool decks, coastal exposure, or chemical environments, go to a stainless carriage bolt in 18-8 or 316 instead.
3) Does the Metallics CB38 meet Buy American requirements for a federal job?
It is flagged compliant for both Buy American and ARRA, which is what a government, school district, or transit procurement file usually needs on a fastener line item. Country of origin is listed as multiple sources, so if your spec requires a single named origin on the certificate, confirm the origin on the lot you receive.
4) Will the CB38 head sit flush and is it tamper resistant?
The head is a mushroom (round) style measuring 1.032 to 1.094 inches across, so it sits as a low dome with no drive recess. There is nothing for a wrench or driver to grab on the head side, which makes it the usual choice where you want the exposed face smooth and hard to back off from outside, as on gates, fence panels, and playground or bench hardware. All tightening happens at the nut.
5) What dimensional standard do these carriage bolts follow?
They are made to ASME B18.5-1990, the round head bolt standard. That matters when a submittal or inspector asks for the governing dimension spec, and it means the head and square neck dimensions will interchange with any other B18.5 carriage bolt of the same 1/2-13 size.
6) Can I get the CB38 carriage bolt in a different length or a larger pack?
The CB38 itself is fixed at 1/2-13 x 4-1/2 inches in a 25-count jar. Other sizes and quantities in the Metallics CB and JCB carriage bolt series are available by request, so if you need the same bolt shorter, longer, or in bulk for a repeat job, ask for the size you want rather than ordering multiple jars.
7) How much does a jar of 25 of these 1/2 inch carriage bolts weigh?
A full jar of 25 comes in at 7.5 lbs. Worth knowing if you are staging multiple jars on a lift or carrying them up to a roof.
