What Size Are Ball Lock Keg Posts?

There are two primary post sizes for standard ball lock kegs.  11/16″ and 7/8″.  These can come in both 6 point and 12 point, compatible variations.  I’ve seen two other post sizes. 5/8″ and 9/16″.  I consider those more non-standard.  This post focuses on 11/16″ and 7/8″.

I usually use a wrench when dealing with ball lock keg posts.  I have one wrench that works with both sizes – See: Hands on Review: “Ball Lock Keg Wrench” – 11/16″+7/8″ Ratcheting Wrench – via Apollo Tools Wrench Set – but having a socket is sometimes super handy and sometimes potentially required.

What about 12 Point vs 6 Point Posts?

For the larger 7/8″ posts I’ve seen both 6 point and 12 point styles.  A 12 point socket will work on a 6 point post, but not vice versa.  For the smaller 11/16″ posts I have only seen 6 point.  Not to say that 12 point don’t exist, I just don’t recall seeing any.

This post looks at both sizes to prove what I’m saying here, however, when looking for a 7/8″ socket, I recommend a 12 point design.  That gives you the flexibility to work with both 6 and 12 point style posts.  For the smaller 11/16″ socket, a 6 point design should work.

These Only Work With Ball Lock Kegs, Why?

These sockets will only work with standard Ball Lock Keg Posts.  Pin Lock Kegs require a special socket that has a notch in it to allow the post pin to slip through.

Conclusions

I have a lot of experience with Craftsman tools.  I think they produce quality tools at generally reasonable prices.  These sockets are well made, generally well priced and work well to remove ball lock posts.

For the smaller 11/16″ ball lock posts it probably makes sense to buy a 6 point socket.  For larger 7/8″ posts it makes sense to me to buy a 12 point socket.  The 6 pt version works with 6 pt ball lock posts, but it’s likely you’ll run into both 6 pt and 12 pt designs.  Getting the 12 pt 7/8″ means you can work with both.

Other Options:

If you want to look around for other potential options…

Search Amazon for “7/8″ deep socket 12 point” and 11/16″ deep socket

I suggest looking for compatible sizes, both for your driver and a proper size for the ball lock posts. you have.  As mentioned previously I recommend 12 pt for 7/8″ sockets.  Also look for quality materials and good reviews.
