US Patent 10076691 Golf club head with heel-side weight plug

A golf club head comprising a body with a heel-side sole opening in communication with a hosel bore, a removable shaft sleeve with a tip sized to fit within the hosel bore, and a weight plug sized to fit within, and at least partially fill, the heel-side opening is disclosed herein. The weight plug, which has a base end with a through-opening, a tip end with a flange, and a side opening in communication with the through-opening, is connected to the shaft sleeve with a screw. When the golf club head is fully assembled, a hosel flange is trapped between the weight plug and the tip end of the shaft sleeve, and tightening the screw causes the weight plug and the shaft sleeve to move towards one another.
