A golf club includes a shaft, a golf club head including a hosel having an aperture to which the shaft being secured, a securing member configured in a cylindrical shape to cover the shaft, the securing member including a first securing portion detachably fitted to the aperture of the hosel, and an insert member configured in a cylindrical shape to cover the shaft, the insert member including a second securing portion being detachably attachable to the aperture of the hosel and a third securing portion being detachably attachable to the first securing portion of the securing member. The golf club is capable of adopting a first mode of securing the first securing portion to the hosel, and a second mode of securing the insert member to the hosel and securing the first securing portion to the third securing portion of the insert member.

In some embodiments, an adjustable putter includes a club body defining a substantially planar face for striking a golf ball, and a hosel including a hosel neck and a hosel adapter configured to be received within a hosel chamber defined by the club body. The hosel adapter defines an interior channel. The adjustable putter also includes a shaft attachable to the hosel neck, and a housing column. The hosel adapter is configured to rotate about the housing column so as to adjust a lie angle of the hosel neck, and the hosel chamber is configured to prevent rotation of the hosel adapter from increasing the lie angle beyond a predetermined value.

A golf club head having a connection assembly with a non-metallic component possessing unique relationships that offer increased durability, weight sayings, and reduced manufacturing costs.

An adjustable shaft and hosel assembly allows for dependent and independent adjustment of a golf club's face angle, loft angle, and lie angle. The adjustable shaft and hosel assembly comprises a shaft sleeve, a hosel portion, a tubular adjustment piece having non-parallel upper and lower surfaces, and a retention feature that provides an engagement between the tubular adjustment piece and the shaft sleeve to prevent the tubular adjustment piece from becoming detached from the shaft sleeve.

A golf club head includes a body defining an interior cavity. The body includes a sole positioned at a bottom portion of the golf club head, a crown positioned at a top portion, and a skirt positioned around a periphery between the sole and crown. The body has a forward portion and a rearward portion. The club head includes a face positioned at the forward portion of the body. In some embodiments, the crown includes a lattice-like structure having thin regions surrounded by a web of relatively thicker regions. In some embodiments, the club head includes one or more stiffening tubes attached between the sole and the crown to improve the acoustic performance of the golf club head.

A golf club head comprises a body having a face, a crown and a sole together defining an interior cavity. The body having a channel located on the sole and extending generally from a heel end of the body to a toe end of the body. A weight member movably positioned within the channel such that a position of the weight member within the channel is able to be adjusted, thereby adjusting a location of a center of gravity of the body. Additionally, adjustment of the weight member provides a maximum x-axis adjustment range of the position of the center of gravity (Max CGx) that is greater than 2 mm and a maximum z-axis adjustment range of the center of gravity (Max CGz) that is less than 2 mm.

Golf putter heads, golf fitting putter heads, golf putters, and golf fitting putters. The putter heads include a body that is one-piece, formed, and generally rectangular, having a base portion having a trailing edge, and a ball strike portion. The ball strike portion has a heal, a toe, a ball striking face, a length measured along the ball striking face from the heal to the toe, and a midpoint along the length. The body is divided into symmetrical halves measured from the midpoint to achieve balance of weight measured along the length of the ball strike portion, with the ball striking face having a loft angle varying from about 0 to about 1 degree +/0.1 degree. The fitting heads include a slot in which weights and/or the hosel may be moved to adjust toe hang.

A golf club includes: a shaft; an adapter having a shaft insertion portion and a fixation portion; a head having a hosel portion provided with a hosel hole and a through hole; and a retaining member detachably attached to the through hole. The fixation portion is smaller in a second direction than in a first direction, the first direction being orthogonal to the central axis of the shaft insertion portion, the second direction being orthogonal to the first direction. The retaining member is configured to extend from a hosel outer wall through the through hole in the second direction so as to press a cutaway portion.

Golf club heads have an opening for receiving a panel with embedded indicia. The panel extends over the opening and includes a composite layer having an interior surface and an exterior surface, embedded indicium coupled to the exterior surface of the composite layer, and a resin layer covering the embedded indicium and the exterior surface of the composite layer. By contemporaneously encapsulating the indicium and composite layer, the resin layer increases durability and prevents the indicium from peeling or falling off of the sole panel upon repeated impacts of the golf club head with a golf ball.
