1. A golf club head comprising:

  • a body having a face, a sole, a crown, and a skirt joining said face, sole and crown, said body having a body center of gravity;

    said body having a coordinate system with an x-axis located horizontal to the club face, a y-axis located vertical to the club face, and a z-axis located through the club face;

    wherein said body comprises a cavity;

    wherein said cavity comprises an open end and a terminal end, said terminal end opposite said open end;

    an elongate weighted insert configured to reside in said cavity, said weighted insert having a first end and a second end opposite said first end;

    wherein said weighted insert comprises a longitudinal insert axis extending along a center of said weighted insert and passing through said first end and said second end of said weighted insert;

    wherein said cavity is configured to receive said weighted insert through said open end in both a first orientation where said first end is adjacent said terminal end of said cavity and a second orientation where said second end is adjacent said terminal end of said cavity;

    a head locking feature located at said open end of said cavity;

    an insert locking member comprising an insert locking feature configured to engage said head locking feature and lock said weighted insert in said cavity;

    wherein said head locking feature comprises female threads and wherein said insert locking feature comprises male threads configured to engage said female threads;

    a second head locking feature located at said open end of said cavity;

    wherein said insert locking member comprises a second insert locking feature configured to engage said second head locking feature and lock said weighted insert in said cavity;

    wherein said second head locking feature is located external to said head locking feature;

    wherein said second insert locking feature comprises a friction member configured to reside between said insert locking member and said body when said insert locking member is installed in said body and provide a level of friction between said insert locking member and said body, preventing said insert locking member from inadvertently loosening relative to said body when said golf club head strikes a golf ball;

    wherein said insert locking member comprises a channel configured to retain a portion of said friction member;

    wherein said open end of said cavity comprises a bore configured to receive said friction member;

    wherein said open end of said cavity comprises a taper located adjacent said bore;

    wherein said friction member comprises a friction member outer diameter and wherein said bore of said open end of said cavity comprises a bore diameter, and wherein said friction member outer diameter is greater than said bore diameter when said insert locking member is not installed in said cavity;

    wherein said taper is configured to deform said friction member as said insert locking member is installed in said cavity.
