Golf club heads and methods to manufacture golf club heads

Abstract

Examples of golf club heads and methods to manufacture golf club heads are generally described herein. In one example, a body portion of a golf club head may include a top portion with a recess and a pocket inside the recess. A plate portion may be coupled to the body portion and may include a flat portion configured to fit inside the recess and a boss portion configured to fit inside the pocket. The boss portion may include a threaded port aligned with a through-port extending from a base portion of the pocket through to a sole portion of the body portion. A fastener may be inserted through a sole-end of the through-port and threadingly coupled to the threaded port to secure the plate portion to the body portion. Other examples may be described and claimed.
