ABSTRACT:
An archery bow limb attachment construction includes a limb bolt washer having a flat undersurface opposed to an outer surface on the limb, a leg extending from the undersurface into a non-round opening in the limb to prevent rotation of the limb bolt washer with respect to the limb, a through-opening having a cylindrical countersink at an end opposed to the undersurface, and an internally threaded lateral opening communicating with the through-opening between the countersink and the undersurface. An annular bearing washer has a cylindrical outer periphery received in the countersink of the limb bolt washer, and a through-opening having a conical countersink remote from the limb bolt washer. A cap screw has a head received in the conical countersink of the bearing washer and an externally threaded shank that extends through the bearing washer, the limb bolt washer and the archery bow limb into an internally threaded opening in an archery bow handle riser. A set screw in the lateral opening of the limb bolt washer locks the cap screw against rotation with respect to the limb bolt washer.
