hosels

The hosel is the part of a golf club head that connects to the shaft. It is located at the heel side of the head and forms the neck that joins the face to the shaft. In modern clubs, the hosel may be a solid extension or a separate sleeve, depending on the design.

The geometry of the hosel influences loft, lie, face angle, and offset, shaping the club's launching characteristics. In irons, the hosel blends the head with the shaft; in woods, it can be a distinct component or integrated into the head. Many contemporary clubs feature adjustable hosels that allow loft and lie changes by rotating a sleeve or swapping inserts, enabling players to tune performance.

Materials and construction: Hosels are typically made from steel or aluminum in metal woods, and may be forged or cast as part of the head. In adjustable designs, a sleeve or insert is connected to the head and accepts the shaft. Manufacturing and tolerances aim to ensure precise alignment and durability.

Performance and maintenance: Hitting the ball on the hosel is a common mis-hit, producing heel-side shots or off-direction results and sometimes signaling alignment or swing issues. When replacing or adjusting shafts, proper fit and torque are important to maintain accuracy and prevent damage. Regular inspection for cracks, corrosion, or looseness helps sustain club integrity.
