Metallics JSBH701 Bolts 1/2-20 X 1-1/2 Hxbt SS (Jar 50)

18-8 is an austenitic stainless that handles general atmospheric corrosion, which covers outdoor exposure and the washdown conditions in chemical and food-processing equipment. Where the environment is aggressive, chlorides or coastal salt spray in particular, 316 stainless is the alloy to move to instead; some chemical environments call for special corrosion resistant materials and added precautions.

Both the Buy American and ARRA compliance flags on the JSBH701 hex bolt read compliant. Country of origin is listed as multiple, so if your specification requires documentation of the producing country on a federally funded project, get the mill or origin paperwork for the lot you receive.

Head width across the flats is 0.736 to 0.750 inch, so a 3/4 inch wrench or socket is the right size. Standard hex head, no washer face or flange to allow for.

Tensile runs 100,000 to 150,000 psi minimum with a 65,000 psi minimum yield, and hardness is Rockwell B95 to C32. That puts it in the same broad tensile band as a grade 5 carbon steel bolt, but stainless work-hardens and galls rather than behaving like heat-treated carbon steel, so for high-preload structural connections a graded carbon bolt is the usual call. Pick the 18-8 when corrosion resistance is what drives the joint.

They come in a jar of 50. Order minimum is 100 count, so the smallest buy is two jars. Other sizes and quantities can be had by request if 1-1/2 inch under head isn't the length you need.

No. The jar holds the 1/2-20 x 1-1/2 hex bolts only. Order matching 1/2-20 hex nuts and 1/2 inch flat or lock washers separately, and keep them in 18-8 stainless as well so you don't set up a dissimilar-metal joint that corrodes at the fastener.

JSBH701 is the part number, in the Metallics SBHC and JSBHC hex bolt series. The J prefix is the jar-packed version of the line.
