Disclosed are components for adjusting loft and bounce angle, and interchangeable faceplate and rear flange styles. Novel milled surface roughness for enhanced spin control is disclosed along with new milling methods for achieving optimal surface roughness. Lightweight hosel and consequent redistribution of mass in club head greatly increases the inertia of the golf club. Centrally located hosel position aids in club head stability on off-center hits. This results in a golf club that hits the ball higher, straighter, longer, and with increased ball spin characteristics. ## Claims ### Claim 1 An adjustable interchangeable golf club head, comprising: a faceplate-based platform capable of receiving various performance enhancing interchangeable adjustment components, the faceplate-based platform including a back surface and a face surface, the face surface defining a surface plane, at least a portion of the face surface of the faceplate made with embossing yielding a total surface depth of less than 180 micro inches, thereby adding additional roughness while remaining in compliance with USGA regulations; an interchangeable, independent one-piece hosel adapter received by the face surface of the faceplate-based platform, whereby the loft of the club can be adapted by interchanging the one-piece hosel adapter, such that the relative placement of weight is shifted down to the faceplate which realigns the weight to the center of the club; and a bounce angle adjustment flange removably and adjustably attachable to the back surface of the faceplate-based platform, said bounce angle adjustment flange including an interchangeable rear flange, providing the ability to modify the bounce angle of the club upon swinging the club. ### Claim 2 (depends on 1) The golf club of claim 1, further comprising a flange mounting ridge located on the back surface of the faceplate-based platform and corresponding to bounce location slots having numerous slot locations in order to be adjustable against the flange mounting ridge, allowing for adjustment for the flange mounting ridge and support for launching the ball. ### Claim 3 (depends on 1) The golf club of claim 1, further comprising recessed openings in the interchangeable rear flange to secure the interchangeable rear flange to the golf club head by securement devices through offset washers. ### Claim 4 (depends on 3) The golf club of claim 3, wherein the securement devices can slightly travel, thereby providing bounce angle adjustment. ### Claim 5 An adjustable interchangeable golf club, comprising: a faceplate-based platform capable of receiving various interchangeable adjustment components; an adjustable hosel ball and socket feature; a bounce angle adjustment flange; a flange mounting ridge located on the back of the faceplate-based platform and corresponding to bounce location slots having numerous slot locations in order to be adjustable against the flange mounting ridge, allowing for adjustment for the flange mounting ridge and support for launching the ball; and a space plate for insertion between the bounce angle adjustment flange and the faceplate-based platform in order to act as a sole width adapter, said sole width adapter including bounce location slots for receiving a flange mounting ridge most advantageously used with an offset washer enabled to accommodate the adjustable height of the flange mounting ridge once installed. ### Claim 6 An adjustable interchangeable golf club head, comprising: a faceplate-based platform capable of receiving various performance enhancing interchangeable adjustment components; an interchangeable, independent one-piece hosel adapter capable of being received by the faceplate-based platform, whereby the loft of the club can be adapted by interchanging the one-piece hosel adapter, such that the relative placement of weight is shifted down to the faceplate which realigns the weight to the center of the club; and a bounce angle adjustment flange removably and adjustably attachable to the faceplate-based platform, said bounce angle adjustment flange including an interchangeable rear flange, providing the ability to modify the bounce angle of the club upon swinging the club, depending on the location of the rear flange, and wherein the faceplate-based platform includes a planar surface, substantially without any traditional dishing milling effects, providing a true advantage during the milling process. ### Claim 7 An adjustable interchangeable golf club head, comprising: a faceplate-based platform capable of receiving various performance enhancing interchangeable adjustment components, the faceplate-based platform including a back surface and a face surface, at least a portion of the face surface of the faceplate made with embossing yielding a total surface depth of less than 180 micro inches, thereby adding additional roughness while remaining in compliance with USGA regulations; an interchangeable, independent one-piece hosel adapter capable of being received by the faceplate-based platform, whereby the loft of the club can be adapted by interchanging the one-piece hosel adapter, such that the relative placement of weight is shifted down to the faceplate which realigns the weight to the center of the club; and a bounce angle adjustment flange removably attachable to the back surface of the face-plate-based platform, said bounce angle adjustment flange including an interchangeable rear flange, providing the ability to modify the bounce angle of the club; wherein the faceplate-based platform includes a textured surface with a 30° angle opposing diamond patterned texture on at least a portion of the face surface of the faceplate-based platform.
