An adjustable shaft and hosel assembly allows for dependent and independent adjustment of a golf club's face angle, loft angle, and lie angle. The adjustable shaft and hosel assembly comprises a shaft sleeve, a hosel portion, a tubular adjustment piece having non-parallel upper and lower surfaces, and a retention feature that provides an engagement between the tubular adjustment piece and the shaft sleeve to prevent the tubular adjustment piece from becoming detached from the shaft sleeve.
