Abstract: A golf club head includes a head body formed with a cavity, and a counterweight unit fitted in the cavity and including a sleeve body and an insert body. The sleeve body has a first end face, a second end face, first and second cavities, and first and second inner walls. The first inner wall has at least one first corner. The second inner wall has at least one second corner out of alignment with the first corner. The sleeve body further has at least one shoulder face formed at a junction of the first and second cavities. The insert body includes an insert portion removably inserted into the sleeve body, and an abutting portion extending outward from the sleeve body and abutting against the first end face. The insert portion has at least one flange engaging the second corner and having a stop face abutting against the shoulder face.

Abstract: A golf club head includes a head body having a recessed area defined in a central area of the head body and abutting faces formed along a periphery defining the recessed area. A soldering seam is formed on an outer periphery defining the recessed area and at least one positioning block is formed on one of the abutting faces and has a bottom face flush with a top face of the recessed area. A striking face is abutted to the abutting faces and the bottom face of the positioning block to allow the soldering seam to securely combine the head body and the striking face.
