Exploring Pool Cue Joint Styles and Pin Sizes: A Comprehensive Guide

Updated: Mar 9

In the world of billiards, the pool cue is more than just a tool; it's an extension of the player's skill and style. While much attention is often given to the design and construction of the cue itself, the joint - where the cue's shaft connects to the butt - is equally important. Alongside various joint styles, the size of the pin used in the joint plays a crucial role in the cue's performance and feel. In this comprehensive guide, we delve into the diverse world of pool cue joint pin sizes, exploring their significance and impact on gameplay.


1. 5/16" Pin:

The 5/16" pin is one of the most common sizes found in pool cues. It strikes a balance between stability and flexibility, providing a secure connection between the shaft and butt while allowing for a slight degree of shaft rotation upon impact. Cue makers often opt for this size due to its versatility and compatibility with a wide range of joint styles, including wood-to-wood and metal-to-wood joints.

2. 3/8" Pin:

Cue enthusiasts seeking enhanced stability and rigidity may opt for cues with a 3/8" pin. This larger pin size reduces shaft rotation upon impact, resulting in a more solid feel and improved consistency in shots. 3/8" pins are commonly used in conjunction with metal-to-wood joints and are favored by players who prioritize precision and control in their gameplay.

3. Speed-Loc Pins:

Speed-Loc pins, renowned for their efficiency, are often standardized to fit specific joint systems like Uni-Loc or Radial. These pins facilitate swift assembly and disassembly, enabling players to effortlessly switch shafts or transport their cues in two pieces. While sacrificing some rigidity, Speed-Loc pins provide unmatched convenience, catering to players who prioritize versatility in their gameplay.

4. 5/16 x 14, 5/16 x 18, and Other Variants:

Within the realm of 5/16" pins, there exist different thread patterns such as 5/16 x 14 and 5/16 x 18, among others. These variations affect how the shaft aligns with the butt upon assembly. For instance, cues with a 5/16 x 14 pin may offer a slightly different feel compared to those with a 5/16 x 18 pin due to the angle of the threads. Players often develop preferences for specific thread patterns based on their individual playing style and comfort.


5. Uni-Loc and Radial Pins:

Uni-Loc and Radial pins represent advancements in cue joint technology, offering precise alignment and enhanced stability. These pins feature a unique design with radial grooves or protrusions that ensure a perfect fit between the shaft and butt. While Uni-Loc and Radial pins may come in different sizes, their primary focus is on providing unmatched accuracy and consistency in gameplay, making them popular choices among professional players.
