[0122] Referring to FIG. 43A, golf club head 4000, including weight recess 4014, first toeward end 4015, removable weight 4016, first heelward end 4017, fastener 4032, fastener axis 4036, weight through hole 4038, first body end 4040, first cover end 4060, second cover end 4070, and / or other features / components may be the same as, or substantially similar to, other golf club heads, which may include weight recesses, toeward ends, removable weights, heelward ends, fasteners, fastener axes, weight through holes, body ends, cover ends, and / or other features / components as discussed herein. In some embodiments, removable weight 4016 may be retained to golf club head 4000 through the use of fastener 4032 fastening along fastener axis 4036, as discussed herein. In embodiments, removable weight 4016 may be retained to golf club head 4000 using fastener 4032 and an adhesive, as discussed herein.

[0123] Referring to FIG. 43B, golf club head 4000, including weight recess 4014, first toeward end 4015, removable weight 4016, first heelward end 4017, fastener 4032, fastener axis 4036, weight through hole 4038, first body end 4040, second body end 4050, first cover end 4060, second cover end 4070, removable weight 4016, fastener 4032, fastener axis 4036, and / or other features / components may be the same as, or substantially similar to, other golf club heads, which may include weight recesses, first toeward ends, removable weights, first heelward ends, fasteners, fastener axes, first body ends, first cover ends, second cover ends, removable weights, fasteners, fastener axes, and / or other features / components as discussed herein. Fastener 4032 may fasten along fastener axis 4036 which may be along an x-direction. Weight recess 4014 and / or removable weight 4016 may be shaped to have at least angle 4037. As discussed herein, removable weight 4016 may appear trapezoidal from a back-to-front direction. Weight recess 4014 may have a shape that is the same as, or substantially similar to, removable weight 4016. As illustrated, angle 4037 may be on a heelward side and bottom side of weight recess 4014 and / or removable weight 4016. In some embodiments, first heelward end 4017 and / or second body end 4050 may be shaped to have angle 4037. Second body end 4050 may fit into first heelward end 4017. A direction of fastener axis 4036 may help secure removable weight 4016 based on angle 4037. Angle 4037 may cause removable weight 4016 to be forced in and toward a leading edge of golf club head 4000. For example, pushing removable weight 4016 from a toeward side via fastener 4032 may direct removable weight 4016 heelward and downward into corner weight recess 4039. This may transfer the x-direction force from fastening fastener 4032 into at least an x-direction force and a y-direction force based on angle 4037 of weight recess 4014 and / or removable weight 4016. Angle 4037 may be between about 60 degrees and about 90 degrees, though it should be appreciated that other angles may be used to create such an effect. This is a novel improvement over existing weights that do not account for minimizing a number of fasteners with squared edges. The presently disclosed technology uses at least one weight angle 4037 to use a single fastener 4032 to effectively secure removable weight 4016 in weight recess 4014. Without the presently disclosed angle, removable weight 4016 may lift, rattle, or otherwise cause unwanted movement and / or sound. In some embodiments, the presently disclosed technology uses only one fastener 4032 on a toeward side of golf club head 4000. It should be appreciated that fastener 4032 or another component may be glued or otherwise adhered and still provide the necessary force to secure removable weight 4016 based on a shape of weight recess 4014 and / or removable weight 4016 created by angle 4037.

[0124] Referring to FIG. 44, removable weight 4016, which may include body portion 4018, cover portion 4020, rear surface 4022, ribs 4026, rib cavities 4028, first body end 4040, body height 4042, body width 4044, second body end 4050, first cover end 4060, cover height 4062, cover width 4064, second cover end4070, first channels 4082, weight height 4084, and / or other features / components may be the same as, or substantially similar to other removable weights, which may include body portions, cover portions, rear surfaces, ribs, rib cavities, first body ends, body heights, body widths, second body ends, first cover ends, cover heights, cover widths, second cover ends, first channels, weight heights, and / or other features / components as discussed herein. For example, removable weight 4016 may be the same as, or substantially similar to, removable weight 3116 except removable weight 4016 may be asymmetrical as discussed herein. In embodiments, removable weight 4016 may be symmetrical, as discussed herein. In some embodiments, removable weight 4016 may have recessed portions more toward first body end 4040 than second body end 4050 from a geometric center.

[0125] Referring to FIG. 45, another view of removable weight 4016 may be illustrated. Referring to FIG. 46, removable weight 4016, which may include front surface 4024, first body end 4040, second body end 4050, first cover end 4060, second cover end 4070, second channels 4092, bumps 4094, and / or other features / components may be the same as, or substantially similar to, other removable weights, which may include front surfaces, first body ends, second body ends, first cover ends, second cover ends, second channels, bumps, and / or other features / components, as discussed herein. Referring to FIG. 47, removable weight 4016, which may include ribs 4026, rib width 4027, rib cavities 4028, rib cavity width 4029, weight depth 4046, and / or other features / components may be the same as, or substantially similar to ribs, ribs, rib widths, rib cavities, rib cavity widths, weight depth, and / or other features / components of other removable weights discussed herein.

[0122] Referring to FIG. 43A, golf club head 4000, including weight recess 4014, first toeward end 4015, removable weight 4016, first heelward end 4017, fastener 4032, fastener axis 4036, weight through hole 4038, first body end 4040, first cover end 4060, second cover end 4070, and / or other features / components may be the same as, or substantially similar to, other golf club heads, which may include weight recesses, toeward ends, removable weights, heelward ends, fasteners, fastener axes, weight through holes, body ends, cover ends, and / or other features / components as discussed herein. In some embodiments, removable weight 4016 may be retained to golf club head 4000 through the use of fastener 4032 fastening along fastener axis 4036, as discussed herein. In embodiments, removable weight 4016 may be retained to golf club head 4000 using fastener 4032 and an adhesive, as discussed herein.

[0123] Referring to FIG. 43B, golf club head 4000, including weight recess 4014, first toeward end 4015, removable weight 4016, first heelward end 4017, fastener 4032, fastener axis 4036, weight through hole 4038, first body end 4040, second body end 4050, first cover end 4060, second cover end 4070, removable weight 4016, fastener 4032, fastener axis 4036, and / or other features / components may be the same as, or substantially similar to, other golf club heads, which may include weight recesses, first toeward ends, removable weights, first heelward ends, fasteners, fastener axes, first body ends, first cover ends, second cover ends, removable weights, fasteners, fastener axes, and / or other features / components as discussed herein. Fastener 4032 may fasten along fastener axis 4036 which may be along an x-direction. Weight recess 4014 and / or removable weight 4016 may be shaped to have at least angle 4037. As discussed herein, removable weight 4016 may appear trapezoidal from a back-to-front direction. Weight recess 4014 may have a shape that is the same as, or substantially similar to, removable weight 4016. As illustrated, angle 4037 may be on a heelward side and bottom side of weight recess 4014 and / or removable weight 4016. In some embodiments, first heelward end 4017 and / or second body end 4050 may be shaped to have angle 4037. Second body end 4050 may fit into first heelward end 4017.
