These Outlaw and Voodoo Weight Bolts will fit inside the weight bolt system of an Outlaw, Voodoo and some Fury Cues. Customize the feel of your cue by adding or subtracting weight bolts from the butt. Choose from weights of 0.5oz, 1.0oz, and 2.0oz. Easy to install just pop off the butt cap from the butt end of your cue and with the use of a 5/16 size Hex Key or Allen Ranch Tool (not included) unscrew the old bolt out and then screw the new one in. Adjusting the weight on your cue could be the factor of winning or loosing a game.
