1/4" locator pins are used in drilling handle scale holes.  The locator pin is inserted in already-drilled holes, allowing you to assure correct distancing between holes.  These pins are .250" stainless steel with Delrin heads so they won't rust.  We recommend drilling "F" size holes (.257") for easy fitting of .250" stock.  Pin length is approximately .5"  These can also be used as replacement pins for the ProSet grinding jig.  Sold in sets of 3.
