    Expanding Pins Hex Head

    Expanding Pins (Hex Head)

    Alignment Pins

    Expanding Pins are precision alignment pins that expand slightly to tighten up hole clearance (.004" expansion range on the smallest diameter, .010" expansion range on the largest diameter). 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 the USA.

    Design Considerations

    carr expanding pins hex head 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.

    Material

    Split bushings, male segments, and spacers > 17-4PH stainless, 17-4PH stainless, Rc 40 min, passivated, dry film lube. Center spindle > Rc 36-40, passivated, dry film lube. Barrel nut and washer > 17-4PH stainless, passivated, dry film lube. Hex nut > 17-4PH stainless, with locking element. DFARS and RoHS compliant.
