Metallics JSBH3L – Frequently Asked Questions
1) Will a 1/4-20 stainless hex bolt hold up outdoors or in a wash-down area?
It is made of 18-8 stainless steel, which gives general atmospheric corrosion resistance and is the usual choice for chemical and food-processing equipment, exterior fixtures and damp rooms. Aggressive chemical exposure (chlorides, pool chemistry, coastal salt spray) is where 18-8 can pit, and 316 stainless is the step up for those environments. Both are austenitic alloys, so they thread into the same nuts.
2) What nut and tapped hole does the Metallics JSBH3L bolt thread into?
It is 1/4-20, meaning a 1/4 inch nominal diameter with 20 threads per inch, so it mates with any standard 1/4-20 UNC nut or tapped hole. Measured shank diameter runs 0.2450 to 0.2500 inch. For a clearance hole, 1/4-20 normally gets a 9/32 inch bore for a close fit or 5/16 inch for a free fit.
3) What wrench size fits the head on the Metallics JSBH3L 1/4-20 hex bolt?
The hex head measures 0.428 to 0.438 inch across the flats, so a 7/16 inch wrench or socket is the right fit. That is the standard across-flats dimension for a 1/4-20 hex bolt, so it'll take a 7/16 open end, box, or socket without any adapters.
4) How strong is an 18-8 stainless 1/4-20 hex bolt compared to a plated steel grade 5?
This one runs 100,000 to 150,000 psi minimum tensile with a 65,000 psi minimum yield, and hardness of Rockwell B95 to C32. That sits below a Grade 5 plated steel bolt on yield, so if you are working to a structural or high-torque spec, stainless is the wrong trade: you buy it for corrosion resistance, not clamp load. For a wet or corrosive location where the loads are moderate, it is the right call.
5) How many bolts come in a jar of Metallics JSBH3L and can I buy fewer?
It ships as a jar of 50, and 50 each is the order minimum, so a jar is the smallest buy. Other sizes and quantities are available by request if 1-1/2 inch length or 50-count does not suit the job.
6) Is this stainless hex bolt acceptable on a federally funded or Buy American job?
Metallics lists the JSBH3L as both ARRA compliant and Buy American compliant, with country of origin recorded as multiple. For an institutional or government spec that requires documented domestic sourcing on each shipment, ask for the certification covering the lot you receive.
7) Is the JSBH3L a hex cap screw or a carriage/socket type bolt?
Hex head, driven with a wrench, not a screwdriver or an Allen key. It belongs to the Metallics SBHC and JSBHC hex bolt series, so if you need a socket cap or a round-head carriage bolt for a smooth exposed face, this is not the part.
