Precision weight adjustment for Katana cues. These individual weight bolts come in half-ounce increments from 0.5 oz to 4.0 oz, allowing you to customize your cue's balance and feel. Each bolt installs with a standard 1/4" allen wrench—simply remove the existing bolt and swap in your preferred weight. Note that bolts are not stackable, so select the single weight that matches your specifications. Essential for players fine-tuning their equipment.
