Carr Lane Manufacturing Co. Hex Head Expanding Pins

Precision alignment pin that expands to tighten up hole clearance (.004" minimum expansion on the smallest diameter, up to .010" minimum expansion on the largest diameter). The pin is an assembly of female split bushings separated by male segments, all on a center spindle, that expands when drawn together. This assembly provides excellent shear strength, comparable to a solid pin. Expanding Pins can be installed in through holes or blind holes.
