A golf club includes a face coupled to a body. A composite axis extends from a heel to a toe of the club and parallel to ground. The face is formed of a fiber composite material including at least first and second sets of ply arrangements. Each of the ply arrangements includes a pair of plies having first and second pluralities of fibers defining first and second angles with respect to the composite axis, respectively. The face has a ball contact surface, an rear surface, and a mid-zone positioned equidistant between the contact and rear surfaces. A majority of the first and second pluralities of fibers of the ply arrangements between the mid-zone and the contact surface are formed of glass fibers, and a majority of the first and second pluralities of ply arrangements between the mid-zone and the rear surface are formed of carbon fibers.

Golf club head having a composite face

A golf club may include a head having a body and a faceplate coupled to the body. The faceplate may have a maximum thickness at a central location and a cross-section intersecting the central location. The cross-section may have continuously variable wall thickness across the faceplate. The faceplate may have a closed non-convex contour curve defined by constant faceplate wall thickness that encloses the central location.

Faceplate of a golf club head

An adjustable assembly includes a golf club shaft, a golf club head having a hosel portion with a hosel opening, a hosel insert, a shaft adapter, and a fastener. The hosel insert is secured to the hosel portion and includes at least one inwardly extending pawl. The adapter extends about a longitudinal axis, and defines a shaft opening. The adapter includes outwardly projecting teeth aligned with the hosel insert. Each tooth includes leading and trailing surfaces. The leading surface is shaped to enable rotational movement of the adapter about the axis with respect to the hosel insert in a first rotational direction. The trailing surface is shaped to selectively engage the pawl to inhibit rotational movement of the adapter with respect to the hosel insert in a second rotation direction that is opposite the first direction. The fastener is releasably coupled to the head and the adapter.

Golf club adjustable hosel assembly

An adjustable assembly includes a shaft, a club head having a hosel portion with a hosel opening, a hosel insert, a shaft adapter, and a fastener. The hosel insert is secured to the hosel portion and includes at least one pawl. The hosel portion or the hosel insert includes a first set of projections. The adapter extends about a first longitudinal axis and includes a second set of teeth aligned with the hosel insert, and a third set of projections for selectable engagement with the first set. Each tooth includes first leading and trailing surfaces. The first leading surface is shaped to enable rotational movement of the adapter about the axis with respect to the hosel insert in a first rotational direction. The first trailing surface is shaped to selectively engage the pawl to inhibit rotational movement of the adapter in a second rotation direction, opposite the first direction.

An adjustable assembly includes a shaft, a club head having a hosel portion, a hosel insert, a shaft adapter, and a fastener. The hosel insert is secured to the hosel portion and includes a plurality of inwardly projecting teeth. Each tooth includes leading and surfaces. The adapter extends about a first longitudinal axis and includes at least one outwardly extending flexible or biased element aligned with the teeth. The leading surfaces are shaped to enable rotational movement of the adapter about the axis with respect to the hosel insert in a first rotational direction. The trailing surfaces are shaped to selectively engage the element to inhibit rotational movement of the adapter in a second rotation direction, opposite the first rotational direction. The assembly is adjustable between several locked positions. Each of the locked positions defines a separate loft and/or lie position of the head with respect to the shaft.

Sole of a golf club head

A shaft for a golf club having a total length and a total weight. The shaft includes first and second tubular portions. The first and second tubular portions are formed of first and second materials, respectively. The second tubular portion has a proximal end and a tip end. The tip end has an outside diameter of less than 0.400 inches. The distal end of the first tubular portion is co-cured to the proximal end of the second tubular portion. The shaft has a resistance to twisting about a longitudinal axis of the shaft, when tested under a torsional stability test and measured at an approximate midpoint of the total length of the shaft, of less than 2.0 degrees in a torsional stability test. The shaft when measured from the tip end of the shaft in a balance point test device has a balance point of less than 46 percent.

Multi-sectional co-cured golf shaft

A golf club vibration dampening and sound attenuation system including an elongated shaft, a club head, a resilient insert assembly, a dampener, and a grip. The shaft has a distal shaft end and a proximal shaft end. The club head is coupled to the distal shaft end, and includes a front wall and a sole portion. The front wall has a rearwardly sloped front strike side and a rear side. The sole portion rearwardly extends from a lower region of the rear side. The rear side and the sole portion define a cavity and a recess. The recess downwardly extends into the sole portion. A resilient insert assembly is positioned in and substantially fills the recess. The insert assembly is coupled to one or both of the sole portion and the lower region. The dampener is disposed within the shaft and has at least one annular radially extending projection.
