Brass shaft shims are a fast and easy way to shim shaft tips into clubheads with larger inside hosel diameters. Sold individually. This standard size shim fits in applications where there is a 0.15" gap such as 0.335" shafts going into a .350" hosel or a 0.355" taper tip shaft into a 0.370" hosel. Both sides of the brass prongs should be abraded when installing.
