5/16 x 3 18-8 Stainless Steel Standard Dowel Pin is used when the assembly needs a cylindrical locator rather than a threaded fastener carrying the lateral location load.

Humid-plant repair work often calls for a stainless dowel when the existing location must be preserved but rust-related sticking is a concern. Material selection should balance moisture exposure, alignment requirements, wear conditions, and the mating component design. Use the nominal diameter, tolerance band, and length together; the dowel sets location while separate fasteners provide clamping force.

Cold Headers supports distributors, OEM repair teams, and plant maintenance groups that need stainless dowel pins matched to a specific drawing.
