Pool Cue Joints Explained: Uni-Loc vs. Radial vs. 5/16×18 vs. 3/8×10

The joint is where your cue’s two halves meet — and it shapes assembly speed, feel, and which spare shafts will ever fit your cue. Here is the plain-English version of the choice.

Quick-Release Joints: Speed and Consistency

Uni-Loc is the best-known quick-release: a stainless pin that locks in about a half-turn with a firm, repeatable hit — standard on Predator, Lucasi, and Poison. Brand variants like Viking Quick Release and Turbo-Lock work on the same principle. Pick quick-release if you assemble and break down often and want the same connection every time.

Wood-Thread Joints: Feedback First

The classic 5/16×18 — standard on every Meucci — and the coarser, faster-assembling 3/8×10 thread into the shaft for a connected, “alive” hit that experienced players use to read the cue ball. The Radial pin refines the idea with a rounded thread profile many players call the smoothest feel in pool.

The Rule That Matters

Joints are not cross-compatible. A Uni-Loc shaft will never fit a Radial butt; a 5/16×18 will not thread onto a 3/8×10. Buy spare shafts by your cue’s exact pin — or ask us and we will confirm the fit before you order.

Our Take

There is no wrong answer, only feel. Try both camps in the shop if you can; otherwise: quick-release for convenience and modern low-deflection pairings, wood threads for traditional feedback. Browse all pool cues or jump straight to a joint-specific collection.
