Product Information
Expanding Pins are precision alignment pins that expand slightly to tighten up hole clearance. This 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. Available in standard pin diameters from 1/4 to 3/4", each in a choice of several lengths. Made in USA.
Operation
Expanding Pins are an assembly of female split bushings separated by male segments, all on a center spindle, that expands when drawn together. Tightening the hex nut with a wrench expands the pin diameter to take up slack and secure the pin in place. Hold center spindle stationary with a hex wrench while tightening.
Design Considerations
Choose a proper pin length such that no split bushings extend beyond the installation hole. All bushings must be contained by the hole in order to exert full pressure and avoid over-expanding the bushings.
