Metallics JCB3SS – Frequently Asked Questions
1) What thread does the Metallics JCB3SS carriage bolt take, and what nut do I need?
It is a 1/4-20 UNC bolt, 20 threads per inch, cut to ANSI/ASME B1.1. So any standard 1/4-20 coarse nut threads on. For a stainless assembly, pair it with a 1/4-20 18-8 stainless nut and washer so you do not mix metals in the joint.
2) Are these 1/4-20 stainless carriage bolts OK for outdoor or damp locations?
They are 18-8 stainless steel made to ASTM F593, so corrosion resistance is good for exterior strut, fence, sign, and damp mechanical-room work. 18-8 is the general-purpose austenitic grade; for salt spray or coastal exposure, 316 stainless is the step up.
3) Can I use Metallics JCB3SS bolts on a federally funded or Buy American job?
Yes. The JCB3SS is flagged compliant for both Buy American and ARRA, which is what a government, school, or transit submittal usually asks for on fasteners. Country of origin is listed as multiple, so if a job requires a single named origin on the certification, confirm that detail before you submit.
4) What hole size should I drill for these 1/4 inch stainless bolts?
The shank runs 0.213 to 0.260 inch outside diameter, so a 1/4 inch nominal hole is the tight fit and 5/16 inch is the normal clearance hole if you need a little play for alignment. Across the flats, the head measures 0.563 to 0.594 inch, which is what matters if the head has to sit inside a recess or a channel slot.
5) How are these 1/4-20 stainless carriage bolts packaged, and what is the smallest quantity I can buy?
They ship in a jar of 100 pieces, and 100 count is the order minimum, so one jar is the smallest buy. The jar weighs about 1070 g. For MRO stockrooms the jar format is handy because it stays closed on a shelf instead of spilling out of a bag.
6) Do these bolts meet a dimensional standard so they interchange with other brands I already stock?
Dimensions are to ASME B18.5 and threads to ANSI/ASME B1.1, so a 1/4-20 x 1-1/2 bolt from another maker built to the same standards will drop into the same hole and take the same nut. Material conformance is ASTM F593 for the 18-8 stainless.
7) Is the JCB3SS the right fastener for attaching to strut or sheet metal, or should I use something else?
It is a through-bolt: it needs a hole in both parts and a nut on the back, so it suits strut, channel, bracket-to-bracket, and wood or panel assemblies where you can reach both sides. If you can only reach one side, a bolt like this will not work and you want a self-drilling screw, a toggle, or a threaded anchor instead.
