Hands on Review: “Ball Lock Keg Wrench” – 11/16″+7/8″ Ratcheting Wrench – via Apollo Tools Wrench Set

Apollo Tools DT1212 SAE Ratcheting Wrench Set includes 5 wrenches of various sizes.  One of those has an 11/16″ end and a 7/8″ end.  Those happen to be the two common sizes for ball lock posts.

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.  The wrench featured here works with what I consider to be the two most common ball lock post sizes 11/16″ and 7/8″.

I own a similar wrench from Craftsman – included in this set.  The Craftsman wrench is geared so that there is an “on” side and and “off” side.  To switch between the two you flip the wrench.  The Apollo adds a flip switch, pictured in this photo, so you can switch between tightening and loosening modes without re-orienting the wrench.


If you’re a ball lock keg owner, I think you should own this wrench or a similar one.  Having one go-to wrench for removing and tightening posts is super handy.  Beyond having the right sizes, the ratcheting function helps make quick work of tightening and loosening posts.
