Metallics JSBH2371 Bolts 1/4-20 X 3-1/4 Hxbt SS (Jar 100)

It is a 1/4-20 bolt: 20 threads per inch on a shank measuring 0.2450 to 0.2500 inch outside diameter. Any standard 1/4-20 UNC nut or tapped hole will take it. Pair it with a stainless nut and washer so you don't set up a dissimilar-metal corrosion problem at the joint.

No. The JSBH2371 is flagged as not Buy American compliant and not ARRA compliant, with multiple countries of origin. For federally funded work carrying domestic-content requirements you will need a domestically produced 1/4-20 stainless hex bolt instead.

Rated at 100,000 to 150,000 psi minimum tensile and 65,000 psi minimum yield, with hardness of Rockwell B95 to C32. That is typical structural-grade stainless territory rather than a soft commodity bolt, but note stainless galls easily under torque, so use an anti-seize compound on stainless-to-stainless threads.

For dry indoor strut, racks, and enclosures, a zinc-plated steel bolt is normally enough and costs less. Go to a 316 stainless bolt like the JSBH2371 where the fastener sees salt air, roof exposure, wash-down, or chemical atmosphere, because 316's molybdenum content resists that attack better than 18-8 stainless and far better than plating that eventually wears through. One caution: do not bolt stainless directly to bare aluminum outdoors without isolating it.

They ship in a jar of 100, and 100 count is the order minimum. The jar pack is handy on a service truck or a shop bench where a bagged count tends to spill. Metallics does offer other sizes and quantities in this SBHC and JSBHC line by request.
