3/8 x 1/2 18-8 Stainless Steel Standard Dowel Pin is a ground cylindrical pin for production tooling that needs positive location in a stainless material callout.

Instrument housings, small fixtures, and inspection nests use standard dowels to keep datum surfaces repeatable through removal and reassembly. This unhardened stainless family trades maximum hardness for corrosion-resistant service by design. Use the nominal diameter, tolerance band, and length together; the dowel sets location while separate fasteners provide clamping force.

Cold Headers brings long-running socket and pin fastener knowledge to replacement, MRO, and production sourcing conversations.
