Metallics JCB121SS – Frequently Asked Questions
1) What thread size and pitch are the Metallics JCB121SS bolts?
They are 1/2-13 UNC, meaning 13 threads per inch in the Unified National Coarse series to ANSI/ASME B1.1. That mates with any standard 1/2-13 nut or tapped hole. Thread body measures 0.444 to 0.515 inch outside diameter.
2) How thick a material can a 1/2-13 x 1 inch bolt actually clamp?
Grip is limited by the 1 inch length measured under the head, so once you account for a nut and washer you are realistically fastening material up to about half an inch thick. For strut, channel, or stacked brackets thicker than that, step up to a longer length in the same 1/2-13 thread rather than forcing this one.
3) Are these Metallics bolts stainless, and will they hold up outdoors?
They are 18-8 stainless steel, the austenitic 300 series grade used for general corrosion resistance, made to ASTM F593. That suits damp, exterior, and washdown locations where plated carbon steel would rust. For chloride-heavy environments such as coastal or pool rooms, 316 is the usual step up.
4) Do these bolts qualify for a Buy American or ARRA-funded job?
The JCB121SS is flagged both Buy American compliant and ARRA compliant, which is what a government, school district, or transit procurement file usually needs on record. Country of origin is listed as multiple.
5) Does the JCB121SS come with nuts and washers?
No. The jar of 50 is bolts only, so order 1/2-13 stainless nuts and 1/2 inch stainless washers separately to match the 18-8 material and avoid mixing plated carbon steel hardware with stainless in a wet location.
6) I need the same bolt in a longer length or a different quantity. Is that possible?
Yes. The Metallics CB and JCB series covers other sizes and quantities beyond the 1/2-13 x 1 inch jar of 50, available by request, so a run of longer lengths for the same job can be matched in the same 18-8 stainless.
