Metallics JSBH552 Bolts 7/16-14 x 1 HXBT SS (Jar 50)

It's a 7/16-14 x 1 inch hex bolt, so 14 threads per inch (UNC coarse) with a shank outside diameter measured at 0.4305 to 0.4375 inch and a 1 inch length under the head. Mates with a 7/16-14 nut or tapped hole.

316 stainless steel. The molybdenum in 316 gives it better corrosion resistance than 18-8 and more strength at elevated temperature, which is why it gets specified for coastal, wastewater, pool chemical, and washdown environments rather than plain 18-8.

The JSBH552 is rated 100,000 to 150,000 psi minimum tensile with 65,000 psi minimum yield, and hardness runs Rockwell B95 to C32. That puts it below a plain grade 8 structural fastener, so don't swap it into a load path that calls out a higher grade. Where corrosion is the governing concern and the load is moderate, the 316 stainless is the better pick.

No. The JSBH552 is listed as not Buy American compliant and not ARRA compliant, with country of origin shown as multiple. For a job with domestic sourcing language in the spec, you need a domestically produced hex bolt instead.

The hex head measures 0.612 to 0.625 inch across the flats, so a 5/8 inch wrench or socket is the right fit.

They ship in a jar of 50 pieces, and the stated order minimum is 100 jars. Jar packaging is what you want on a service truck or a parts crib where loose bolts get lost.

The JSBH552 is fixed at 7/16-14 x 1 inch in a 50 piece jar, but other sizes and quantities in the SBHC and JSBHC hex bolt line are available by request.

The SBHC and JSBHC hex bolt line is aimed at the electrical, plumbing, heating and air conditioning trades, so typical use is strut and channel assembly, equipment mounting, hanger and bracket work, and anywhere a corrosion resistant 316 stainless bolt is needed for rooftop or mechanical room hardware.

Head height on the 7/16-14 bolt falls in the 0.272 to 0.291 inch range, which matters if you are counting grip length against a tight clearance or a counterbore. A packed jar comes in at 2,699 g.
