Pool Cue Joint Types Compared 2026: Radial, Uni-Loc, 3/8×10, Speed Joint, and How Each Hits

The joint sits halfway up the cue and gets almost none of the attention. It deserves more. The pin and collar where the shaft screws into the butt are doing two jobs at once. They are mechanically fastening two precision parts of the cue, and they are transmitting hit information from the ferrule all the way down to the wrap. Change the joint and you change the hit. Change the joint material and you change the hit again. The joint is one of the quiet variables that separates a cue you outgrow in two seasons from a cue you carry for fifteen years.

This guide walks through the four most common joint families on the modern table. Radial joints from Predator and a handful of custom makers, the Uni-Loc family that has spread across nearly every premium brand, the traditional 3/8 x 10 wood-to-wood and stainless variants found on Schon and McDermott customs, and the Pechauer Speed Joint that has its own loyal following. Each section covers the geometry, the hit, the maintenance reality, and the kind of player who tends to land on it after a few cues.

Radial Joints

Radial joints use a screw thread that runs along the axis of the pin with no flat at the bottom of the joint collar. The threads engage continuously as the shaft turns onto the butt, which is why a radial cue feels almost self-aligning when you screw it together. Predator made the Radial pin famous, and it remains the joint of choice on the brand’s BLAK and Throne lines. The hit is firm and bright. The thread engagement is uniform, so there is no flat to act as a vibration sink, and the shaft transmits more high-frequency information than most flat-faced joints.

Radial joints reward players who hit firm and play with a lot of inside English. The hit feedback is high enough that a player who pinches inside spin can hear and feel the contact in the wrap. The downside is that radial joints are unforgiving of dirt. If a thread picks up shaft chalk or rosin from a player’s hand, the joint will start to feel sluggish, and the only fix is a thread brush and a careful wipe with a microfiber cloth.

If you want to study the radial hit in the shop, the Predator PREBLK54 BLAK Series Cue is the canonical reference. You can also try the Predator P3 Black No Wrap PREP3BN for the same joint family at a lower price point. Both ship with a Radial collar and pair with the brand’s REVO Radial shafts, which is why so many players who land on Predator never leave.

Uni-Loc

Uni-Loc is a quick-release joint that uses a short pin with a deep thread and a closed collar that bottoms out against a flat face. The shaft only needs five or six full turns to seat fully, which is a quality-of-life detail that matters more than it sounds when you are putting the cue together in a dim bar after a long match. The hit on a Uni-Loc joint sits between a Radial and a 3/8 x 10. It is brighter than wood-on-wood, softer than a pure Radial, and very consistent from one cue to the next because the flat face acts as a tuning fork.

Uni-Loc has spread because it is licensable. Predator uses it on the P3 Uni-Loc variants. Mezz uses a variation on its Wavy Joint that takes Uni-Loc geometry. Cuetec uses a version on its Cynergy line. Almost every premium brand has at least one model with a Uni-Loc pin because customers want shaft interchangeability across cues. If you own a Predator P3 with Uni-Loc and a Cynergy with Uni-Loc, your spare REVO shaft will install on either cue without an adapter.

The Cuetec Cynergy CT110NW Truewood No Wrap is a clean example of the Uni-Loc family on a softer carbon shaft profile. The Carbon Fiber Shafts category page lets you filter Uni-Loc compatible shafts across multiple brands so you can build a kit that travels well across two or three cues without changing shaft personality.

3/8 x 10 Wood and Steel

The 3/8 x 10 thread is the classic American joint, and it remains the favorite of most custom cue makers. The pin is wider, the threads are coarser, and the joint can be specified in either solid wood, hybrid wood with a brass insert, or stainless steel. Each variation produces a measurably different hit. Wood-to-wood 3/8 x 10 has the softest hit of any joint in this guide, with the most muted feedback and the slowest energy return. Players who came up on snooker cues, or on cues from the Joss and Schon era of the late twentieth century, tend to feel most at home here.

A stainless-steel-pin 3/8 x 10 is a different animal entirely. The hit is sharper, the feedback is louder, and the cue rings rather than thuds when you tap the joint with the butt of your hand. Schon, McDermott, and most Jacoby builds default to stainless on the 3/8 x 10 pin, which is why those cues are often described as having an old-school hit with modern brightness. The McDermott G521R G Series Cue is a good in-shop reference for what a stainless 3/8 x 10 hit feels like in 2026.

The 3/8 x 10 family also covers most of the Jacoby and Viking lineup. The Jacoby Pool Cues category page is worth browsing if you want to compare price points within the same joint geometry. One thing to watch on a 3/8 x 10 is the cleanliness of the collar threads. The pin is wide, which means it picks up more debris than a thinner pin, and it benefits from a quick brush every match.

Pechauer Speed Joint

The Speed Joint is Pechauer’s own quick-release pin, and it deserves its own section because it does not behave like any of the families above. The pin is shorter than a 3/8 x 10 and uses a multi-start thread that allows the shaft to seat fully in two or three turns. The hit is in the family of a wood-to-wood 3/8 x 10 but with the convenience of a Uni-Loc-style seating speed. Players who want the classic Pechauer hit but cannot stand the slow assembly of a five-turn pin tend to land here.

The Pechauer JP21G Pool Cue with Irish Linen Wrap and Speed Joint is the cleanest in-shop example, and the Pechauer Pro H Sneaky Pete at a more affordable price has the same Speed Joint geometry. Both are popular with players who came up on traditional cues and want a modern convenience layer over a classic hit.

How Joint Material Changes the Hit

The pin geometry is half the story. The collar and pin material is the other half. A radial pin set in a phenolic collar plays brighter than the same pin in a steel collar. A 3/8 x 10 wood pin in a wood collar plays softer than the same pin in a brass insert. A Uni-Loc pin in an aluminum collar plays differently than the same pin in a stainless collar. Brands tune these material pairings deliberately. The Predator BLAK pairs a steel pin with a steel collar for brightness. The Schon pairs a stainless pin with a brass-lined wood collar for warmth.

If two cues feel different and you cannot explain why, the joint material pairing is often the culprit. Spend a few minutes at the shop pressing both cues together at the joint with your palm. You can feel the resonance difference even before you take a shot.

Which Joint Should You Pick

The honest answer is that joint choice should follow your stroke. Players who hit firm and play with a lot of English tend to gravitate to radial and steel pins because the feedback supports the level of force they are applying. Players who hit soft and rely on touch tend to prefer wood-on-wood 3/8 x 10 or the Pechauer Speed Joint because the hit does not interrupt the touch shot information traveling up the cue. Most amateurs land somewhere in the middle and end up on Uni-Loc because it splits the difference and accepts shafts from multiple brands.

If you are still deciding, the entry point is the Pool Cues category. Filter by brand to land on the joint family that brand prefers, then read a few of the product descriptions to confirm the pin type. A second cue in the same family is almost always a better investment than a second cue in a different family, because shaft interchangeability matters more than most amateurs realize until they break their primary shaft in the middle of a regional tournament and need a backup that screws in without an adapter. Joint type is one of the few cue decisions you make once and live with for years. Spend the time now and the cue will do its job without you noticing it later.
