A golf club head is formed to have multiple laminations above a sole plate defining a keel; a bolt is connected to the sole plate at the keel and holds the laminations positively clamped together; and the keel forwardmost surface may be sloped to transfer ground impact force upwardly to the laminations via the sole plate, and also via the bolt. A vertical bore is formed in the head to receive the bolt, and the bolt is inserted into the recess and tightened to the sole plate above the keel, to compress the laminations. Synthetic resin also bonds the bolt to the compressed laminations, along the bolt length. The club head and bolt head are ground to provide a smooth top surface.
