A golf club head includes a club head body and a weight member that is secured to the body. The weight member is constructed to utilize lateral forces to couple to the head body to minimize the structure required to retain the weight member, and the weight member is preferably constructed so that it has a low profile.

Described herein are embodiments of golf club heads having a balance of the following parameters: a low and back club head center of gravity position, a high moment of inertia, a large Ixy product of inertia, and low aerodynamic drag. Methods of manufacturing the embodiments of golf club heads having a balance of club head center of gravity position, moment of inertia, product of inertia, and aerodynamic drag are also described herein.

A golf club head that includes a body defining an interior cavity and an exterior surface, the body including a face disposed within a forward portion and extending between a toe and a heel, a sole defining a bottom portion of the golf club head, and a crown defining a top portion of the golf club head. The golf club head further includes a front weight assembly having a first weight removably secured with a first fastener and a second fastener, the front weight assembly being disposed forward of a head center of gravity. The first fastener is disposed on a heel side of the front weight center of gravity, and the second fastener is disposed on a toe side of the front weight center of gravity.

Embodiments of golf club heads and methods to manufacture golf club heads are generally described herein. In one example, a golf club head may include a body portion having an interior cavity, a front portion, a back portion, a toe portion, a heel portion, a sole portion, and a top portion. A face portion is attached to the front portion to enclose the interior cavity. The golf club head may further include a port on the body portion that is connected to the interior cavity. A first mass portion may be coupled to the body portion such that the port is configured to receive the first mass portion to close the port. A second mass portion may be coupled to the body portion and include a different material than a material of the first mass portion. The maximum width of the interior cavity may be below a horizontal midplane of the body portion and above the port. The interior cavity may be at least partially filled with a filler material from the port. The interior cavity may at least partially extend over the port at a location of the maximum width. Other examples and embodiments may be described and claimed.

A golf club head includes a club body and a resting face angle adjuster. The club body includes a crown opposite a sole, a toe end opposite a heel end, a back end opposite a face, and a hosel. The sole includes a sole surface. The resting face angle adjuster includes an adjustment member having a keel surface, and a recess formed in the sole such that a portion of the sole surface at least partially bounds the recess. The adjustment member is disposed in the recess and positionable between a first adjustment position and a second adjustment position. In the first adjustment position, the keel surface is at a first distance relative to the portion of the sole surface. In the second adjustment position, the keel surface is at a second distance relative to the portion of the sole surface not equal to the first distance in the direction.

A method of forming a golf club head that is capable improving on the inertia properties of a golf club head all while also improving the Center of Gravity (CG) location is disclosed herein. More specifically, the method forms a golf club head that achieves a relative low Moment of Inertia (MOI) about the Z-axis (MOI-Z) as well as a relatively low MOI about the Shaft-axis (MOI-SA).

Embodiments of golf club heads and methods to manufacture golf club heads are generally described herein. In one example, a golf club head includes a body portion with an interior cavity, a face portion, a first port, and a second port connected to the interior cavity. The second port includes first and second openings, a second-port first portion, and a second-port second portion. The second-port first portion extends from the first opening to the second opening, and the second-port second portion extends from the second opening to the interior cavity. A portion of the interior cavity below a horizontal midplane of the body portion and between the second port and a heel portion edge of the body portion is closer to an outer surface of the back wall portion than the second opening of the second port. Other examples and embodiments may be described and claimed.

Some embodiments of the lightweight golf clubs described herein include a thin crown, a thin sole, a mass efficient weight system, and a thin faceplate to maximize performance gains (e.g., ball travel distance, impact efficiency, and ball speed) targeted to individuals with swing speeds less than 85 mph. As will be further described below, in order to achieve a lightweight golf club head (having a thin crown, a thin sole, a mass efficient weight system, and a thin faceplate), the golf club head further comprises a crown-to-faceplate bridge and a sole-to-faceplate bridge to control the characteristic time (CT) properties of the golf club head.

A multi-material golf club head having an improved performance is disclosed. More specifically, the present invention relates to a multi-material golf club head having a metallic frontal striking face portion and aft body portion with a crown opening and a sole opening that are covered by a composite crown sub-shell and a composite sole sub-shell, respectively.

Putter type club head with vertical groove patterns are described herein. A putter type club head comprises a putter face having a plurality of first curved grooves and a plurality of second curved grooves. The first curved grooves and the second curved grooves intersect each other at a plurality of points across the putter face. The width and depth of the first curved grooves and the second curved grooves can vary across the putter face in a direction extending from a heel end to a toe end, and/or in a direction extending from a top rail to a sole. The curved groove pattern provides consistent ball speed performance for any impact location on the putter face.
