DOWEL PINS

DOWEL PINS

The primary function of pins are to align two parts or maintain a fixed position between them. Machined pins can be either straight (cylindrical) or tapered (conical). Straight pins can be further divided by how tightly they fit in a hole. They can be either “free-running” or designed to have an interference fit to thwart disassembly. Nickel Systems can machine pins per your print. Our specialty is short runs in highly corrosion resistant nickel-based alloys.
