Dowel Pins also referred to as Parallel Pins, are commonly used to retain parts in a fixed position or to preserve alignment. Accurately ground to plus 0.0002, minus 0.0000 of the stated diameter and + or -0.010 of the length, they are chamfered at both ends for easy insertion. A selection of sizes and lengths is a useful addition to the well-equipped shop or laboratory. Type 316 Stainless Steel are the most corrosion resistant dowel pins. May be mildly magnetic.
