Metallics JSBH47D Bolts 1/2-13 X 1-1/2 Hxbt SS (Jar 50)

18-8 austenitic stainless gives general atmospheric corrosion resistance, which covers outdoor exposure and the kind of wash-down duty you see in food processing and chemical handling equipment. Aggressive chemical environments are a different matter and may call for 316 or another alloy plus added precautions, so don't treat 18-8 as a blanket answer for chemical service.

Tensile runs 100,000 to 150,000 psi minimum with 65,000 psi minimum yield, and hardness is Rockwell B95 to C32. That puts it in the same tensile neighborhood as a grade 5 carbon bolt but with a lower yield point, so for a joint sized on grade 5 or grade 8 torque figures, check the load before substituting stainless. Where corrosion is the governing concern, the 18-8 is the right call.

Yes. The JSBH47D hex bolt is flagged Buy American compliant and ARRA compliant, with country of origin the United States. That matters if you're buying for federal, state, or institutional jobs with domestic-content requirements.

They ship 50 to a jar, and 50 pieces is the order minimum, so the jar is the smallest unit. Metallics offers other sizes and quantities of the hex bolt line by request.

Both are austenitic stainless cap screws. The 18-8, which is what the JSBH47D is made from, handles general atmospheric corrosion and typical chemical or food-processing equipment duty. Move to 316 when the environment is more aggressive, chlorides and marine exposure being the usual reason.

At 1-1/2 inches overall under the head, a 1/2-13 bolt of this length is fully or near fully threaded, so figure the whole 1-1/2 inches as usable grip minus whatever nut and washer stack you add. For thicker assemblies, step up to a longer length from the SBHC and JSBHC hex bolt series.
