Metallics JSBH413 Bolts 1/4-20 X 3-1/2 Hxbt SS (Jar 100)

18-8 stainless is an austenitic alloy used where you need general atmospheric corrosion resistance, which covers most outdoor, damp, and washdown work, including chemical and food-processing equipment. It is not the answer for every chemical exposure. Aggressive chlorides or specific process chemicals call for 316 stainless or another specialty alloy instead.

The JSBH413 runs 100,000 to 150,000 psi minimum tensile with a 65,000 psi minimum yield and a hardness of Rockwell B95 to C32. That is in the same tensile neighborhood as a common medium-strength plated steel bolt, but the yield is lower, so stainless stretches sooner under load. For a structural connection carrying real tension, spec a rated alloy bolt; use this where corrosion resistance drives the choice.

These 1/4-20 x 3-1/2 stainless hex bolts ship in a jar of 100, and 100 count is the minimum order, so the jar is the smallest unit. It's a shop or truck-stock pack rather than a loose-count buy. Metallics does make other sizes and quantities in the same hex bolt line available by request.

The JSBH413 hex bolt is flagged both Buy American compliant and ARRA compliant in Metallics' product data, which is what a government, school, or healthcare procurement file usually needs on a fastener line item.

A jar of JSBH413 is bolts only. No nuts or washers are included. The 1/4-20 machine thread runs the length you engage, so it either takes a 1/4-20 nut or threads into a 1/4-20 tapped hole. For corrosion work, match the hardware to the bolt and use 18-8 stainless nuts and washers so you aren't pairing stainless with plated steel in a wet location.
