Abstract: A screw for use with a golf club head is disclosed herein. The screw comprises a head portion with a compressible feature that more securely retains the screw within a receptacle in the golf club head. The compressible feature preferably is a plurality of tapered extensions that can be compressed inwards by a tapered portion of the receptacle, creating spring tension between the head of the screw and the tapered portion of the receptacle. This helps to prevent the screw from becoming dislodged from the golf club head when it is in use.

Abstract: A screw comprising a drive part, a threaded part, and a retaining ring is disclosed herein. Each of the drive part and the threaded part comprises a plurality of interface surfaces that transmit torque from the drive part to the threaded part and prevent the parts from disengaging from one another during use. Each plurality of interface surfaces forms one or more geometric shapes that create additional friction between the drive and threaded parts, and may further include mating pins and holes to prevent the parts from detaching from one another. The retaining ring, which removably connects the screw to a wrench during assembly of the screw with a receptacle, is disposed within a cavity formed when the drive part is assembled with the threaded part.

Abstract: The skid wheel accessory for a receiver hitch is removably installed in the receiver hitch receptacle of a vehicle to protect the hitch receptacle and other low and rearward vehicle components from damage when the vehicle negotiates a rising ramp or similar slope change from a level surface. The skid wheel accessory includes a heavy hollow steel tube or solid bar that fits closely within the conventional receiver hitch receptacle of the vehicle. The forward portion of the bar or tube has a lateral passage therethrough, for accepting a hitch pin to secure the accessory in the hitch receptacle. An axle extends across the rearward end of the bar or tube, having at least one (preferably two) solid steel wheel(s) thereon. The wheels contact the underlying surface before other components of the vehicle when negotiating a ramp or slope, thus sparing the hitch receptacle and other vehicle components from damage.

Abstract: A C-shaped golf club head is disclosed herein. The body has a striking plate wall, a crown section, a sole section and a rear wall. The golf club head also has a plurality of weight members positioned on the rear wall of the body. Each of the plurality of weight members is movable along the rear wall.
