Claim:
A golf club head oriented in a reference position and comprising: a main body comprising: a heel, a toe, a top portion, and a bottom portion; a striking face having a face center; a forward-most extent, and a rearward-most extent; an interior surface, and an exterior surface; a hosel; a peripheral edge; an overall club-head width measured in a heel-toe direction; an overall club-head length measured in a forward-rearward direction; and a geometric center; and a discrete weight member coupled to the interior surface of the main body, the weight member comprising a density of at least about 3 g/cm 3 , a projection area, in a top plan view, of at least about 2 cm 2 , a first surface that is proximate the interior surface of the main body, and a second surface that is distal the interior surface of the main body, a majority of the mass of the weight member located in a three-dimensional space, bounded, in a top plan view, between the peripheral edge and an imaginary inner boundary inwardly offset from the peripheral edge by a distance of 0.3 times the overall club head length, wherein, in an imaginary vertical plane that passes through the weight member: the interior surface of the main body comprises a first point and a second point; an imaginary line passes through the first point and the second point; a first imaginary boundary line perpendicular to the imaginary line and passing through the first point passes through the weight member; a second imaginary boundary line perpendicular to the imaginary line and passing through the second point passes through the weight member; between the first point and the second point, the interior surface of the main body comprises an irregularity factor of at least 1.2; and between the first point and the second point, the weight member comprises a distribution factor of at most 1.0 and a conformity factor of at most 0.07.
