Metallics JSBH26 Bolts 3/8-16 X 3 Hxbt SS (Jar 50)

The JSBH26 is a 3/8 inch diameter hex bolt with 16 threads per inch, so it mates with standard 3/8-16 UNC nuts and tapped holes. Measured shank outside diameter runs 0.3690 to 0.3750 inch. Note that 16 TPI is the UNC coarse pitch for 3/8; a 3/8-24 fine thread nut will not thread onto it.

18-8 stainless is what the JSBH26 is made from, which gives general atmospheric corrosion resistance, the grade commonly specified for chemical and food processing equipment. For aggressive chemical exposure, 316 stainless or other specialty corrosion resistant material is the better call. Both 18-8 and 316 are austenitic alloys, so they are non-magnetic as supplied and will not rust-stain a finished surface the way plain steel does.

Tensile strength on this 18-8 stainless hex bolt is 100,000 to 150,000 psi minimum with a 65,000 psi minimum yield, and hardness runs Rockwell B95 to C32. That is below a Grade 5 carbon steel bolt's 120,000 psi tensile minimum, so do not swap it into a structural or high-preload connection without checking the engineer's spec. Where corrosion resistance drives the choice, as in most electrical, plumbing, and HVAC support work, these numbers are more than adequate.

No. The JSBH26 is not Buy American compliant and is not ARRA compliant, with country of origin listed as multiple. On a federally funded job with domestic sourcing language in the spec, you will need a domestically produced hex bolt instead.

These ship as a jar of 50 pieces, and 50 each is the order minimum, so the jar is the smallest unit. Metallics does make other sizes and quantities in the SBHC and JSBHC hex bolt series available by request if 3/8-16 x 3 is not the length you need.

Length on the JSBH26 is 3 inches, measured from under the head, and that is the figure to work from when stacking up your material thickness plus washers and nut. The head itself adds 15/64 inch above the surface. If your stack-up needs the thread to run all the way to the head, confirm the thread length for this size before ordering, since a 3 inch hex bolt in this diameter is commonly part-threaded.

Bolts only. The jar of 50 contains the 3/8-16 x 3 hex bolts and nothing else, so order 3/8-16 stainless hex nuts and matching flat or lock washers separately. Keep them in 18-8 stainless to match the bolt, since mixing plated carbon steel nuts onto stainless bolts in a damp location sets up galvanic corrosion at the joint.
