Metallics JSBH33 Bolts 1/2-13 X 2 Hxbt SS (Jar 50)

They are 1/2-13 coarse thread, 2 inches long, in 18-8 stainless. Thread count is 13 per inch and the shank measures 0.4930 to 0.5000 inch, so they run in any standard 1/2-13 nut or tapped hole. Across the flats the hex head measures 0.736 to 0.750 inch, so a 3/4 inch wrench or socket is the tool.

18-8 austenitic stainless is used where general atmospheric corrosion resistance is needed, including chemical and food-processing equipment, so outdoor racks, damp mechanical rooms and washdown areas are within its normal range. Aggressive chemical exposure is the exception; those environments may call for 316 or another specialty alloy instead.

The JSBH33 is rated 100,000 to 150,000 psi minimum tensile with 65,000 psi minimum yield, and hardness runs Rockwell B95 to C32. That is in the neighborhood of a grade 5 carbon steel bolt on tensile but with a lower yield, so stainless is the choice when corrosion drives the decision rather than raw clamp load. For high-load structural connections, spec a carbon steel grade 5 or grade 8 bolt instead.

No. The JSBH33 hex bolts are not Buy American compliant and are not ARRA compliant, with country of origin listed as multiple. On a federally funded job with domestic sourcing requirements, you will need a domestically produced stainless hex bolt instead.

They ship 50 pieces to a jar, and 50 each is the order minimum, so the jar is the smallest unit. Jar packaging keeps loose 1/2-13 hardware together on a van or a job cart. Other sizes and quantities are available by request.

No. The JSBH33 jar is bolts only, 50 hex bolts in 1/2-13 x 2 inch stainless. Order matching 1/2-13 stainless hex nuts and flat or lock washers separately, and keep them in the same 18-8 stainless to avoid mixing metals at the joint.
