Carr Lane Expanding Pins are precision alignment pins that expand to provide the highest tolerance alignment of two holes. These Expanding Pins are an assembly of female split bushings separated by male segments, all on a center spindle, that expands when drawn together. The assembly of these Expanding Alignment Pins provides excellent shear strength, comparable to a solid pin. Expanding Alignment Pins are offered with a cam handle or hex head, available in standard pin diameters from ¼ to 3/4” in several available lengths. Carr Lane Expanding Pins are proudly made in the USA. Browse both variations of Expanding Alignment Pins below.
