Kegerator Leveling Feet Thread Sizes: What to Match

What thread size means on a listing

When a kegerator listing mentions leveling feet, the thread size is the measurement of the threaded stud that screws into the cabinet. It is usually written as a metric size like M8 or an imperial size like 1/4-20. The letter M stands for metric, and the number after it is the diameter in millimeters. The second number, when present, is the thread pitch, which is the distance between threads.

Matching the thread size matters because replacement feet must screw into the same threaded insert in the cabinet. If the diameter or pitch does not match, the foot will not seat properly. The thread size is one of the few details that a listing may state in the bullet list or the dimensions section, so read those lines before you buy a replacement. For more on what to look for in a listing, see our guide on reading a kegerator listing.

• M8 is a common metric size, meaning an 8 mm diameter thread.
• 1/4-20 is a common imperial size, meaning a 1/4 inch diameter with 20 threads per inch.
• The pitch is only relevant when the thread is fine or coarse; some listings state it, others do not.

Common thread sizes you will see

Kegerator leveling feet come in a range of thread sizes, but the most frequent on home and commercial listings are M8, M10, and 1/4-20. M8 is common on compact and undercounter units, while M10 appears on larger full-size cabinets. Imperial sizes like 1/4-20 are often found on conversion refrigerators or units built to North American standards.

The thread size is not the same as the foot's base diameter. A foot can have an M8 thread and a 1.5 inch base. When you compare listings, separate the thread size from the base size and the height range. The base diameter affects stability, and the height range determines how much you can adjust the cabinet. If you are comparing cabinet widths, our 24 inch guide explains how size names relate to the overall footprint.

How to read the thread size in a listing

Look for the thread size in the bullet list, the specifications table, or the dimensions section. A listing may say "leveling feet with M8 thread" or "1/4-20 threaded feet." If the listing does not state the thread size, that is a missing detail you should ask the seller about before buying a replacement.

Some listings describe the feet as "adjustable" without giving the thread size. That tells you the feet can be turned to change height, but it does not tell you the thread diameter. For a replacement, you need the exact size, not just the fact that the foot is adjustable. When a listing omits a detail, it is often because the seller expects you to know the model, so check the manufacturer's page for the model's manual.

Replacing leveling feet in general terms

Replacing a leveling foot is a straightforward task: you unscrew the old foot from the threaded insert, then screw in the new one. The thread size must match, and the new foot should have the same base shape so it sits flat on the floor. If the foot has a lock nut, you tighten that after setting the height.

Before you order a replacement, measure the old foot's thread diameter with a ruler or caliper if you can. Compare that measurement to the listing's stated thread size. If you cannot measure, look for the model number and check the manufacturer's manual, which often lists the thread size for service parts.

Adjusting the height with leveling feet

Leveling feet are turned to raise or lower each corner of the kegerator. The thread pitch determines how much height changes per full turn. A coarse thread like 1/4-20 changes height more per turn than a fine thread like M8x1.25. This matters if you need precise leveling on an uneven floor.

When you adjust the feet, turn them in small increments and check the cabinet with a level. The goal is to have the kegerator stable and the door aligned. If the listing states a height range for the feet, that range tells you how much adjustment is possible from the lowest to the highest setting. For a unit that will sit under a counter, the undercounter guide explains how height and leveling work together.

What to check before buying replacement feet

Before you buy replacement leveling feet, confirm three things: the thread size, the base diameter, and the height range. The thread size must match the cabinet insert. The base diameter should be similar to the original so the foot does not sink into soft flooring or rock on a hard surface. The height range should cover the adjustment you need.

Also check whether the listing includes a lock nut or a washer. Some feet come with a nut that holds the height setting, while others rely on friction. If the original foot had a lock nut, choose a replacement that includes one, or the foot may turn on its own over time. For a full-size unit, the full size guide covers how leveling affects door alignment and stability.

Questions

What does M8 mean on a leveling foot?

M8 means the thread diameter is 8 millimeters. It is a common metric size for kegerator leveling feet.

Can I use any leveling foot on my kegerator?

No, the thread size must match the threaded insert in the cabinet. If the diameter or pitch differs, the foot will not screw in properly.

How do I know the thread size if the listing does not state it?

Measure the old foot's thread with a ruler or caliper, or check the manufacturer's manual for the model. If neither is possible, contact the seller.

Does the thread size affect how much I can adjust the height?

Yes, the thread pitch determines how much height changes per turn. A coarse thread changes height more per turn than a fine thread.

Are leveling feet the same as casters?

No, leveling feet are stationary and adjust height, while casters are wheels that allow movement. Some kegerators have both, but they are different components.
