Weight bolts for Lucasi Brand cues. These weight bolts come in 0.5oz increments and are used for weight changes on Lucasi brand cues. Before purchasing a weight bolt, we recommend that you determine the weight of the bolt in your current cue, then size up based on how much you want to increase your overall cue weight. Please also note that some Lucasi models have a screw in bumper where the screw through the bumper will thread into the weight bolt. All Lucasi weight bolts have the threading on this inside of the bolt so these will work on either type of bumper style.
