This is your number one source for information regarding measurements, uses, and sizing. This guide should educate you on the solutions we have available, when to use them, and how to go about measuring them. This is essential during the process of choosing the best match for your use.

Adjustable Feet are an extremely popular component employed inside a vast array of industries. From use as machinery mounts all the way to screw in feet for furniture, they can be found almost anywhere and everywhere.

When To Use Adjustable Feet?

When raising a piece of furniture or machinery:

One of the most popular uses for these types of feet is to raise a piece of furniture or machinery. The longer the thread size, the more height that you are able to add by screwing/un-screwing to your required height. The majority of feet provide stability even at the longest of thread sizes to prevent wobble.

To level off an object:

As well as being able to add height to an object, specific types of Adjustable Feet are designed specifically for levelling uses. These include articulating and tilting feet. This design is recommended for uneven floors, or applications with varying levels of height.

To reduce vibrations and noise:

When looking to reduce the vibrations and noise experienced through a foot, these products are ideal. They allow for a larger distance between the floor and the object in question, which reduces overall vibrations and noise that may have otherwise been prevalent. We recommend our Rubber Base Feet for these types of installations, thanks to the optimal properties that rubber provides.

When frequent height adjustment is required:

Another common use for these feet includes their use as height adjusters. This allows for an object to be raised or lowered based on your requirements. This is frequently seen with portable stands and stalls, where they are regularly adjusted to suit the daily needs. Slotted Head & Polyamide Feet are suggested for this ease. This is thanks to their ability to be adjusted from above (using either an allen key or a screwdriver).

Why Use Adjustable Feet?

Now you have a better idea of exactly when these type of feet are used, we are going to outline a couple of the main reasons why they are used.

Some of the main reasons why these products are used is to support a heavy load. This is as well as to distribute the weight accordingly, something that many other solutions may struggle with.

Adjustable Feet can be specifically chosen to suit their use and weight requirements. Larger thread sizes and base diameters provide the best weight capabilities in comparison to smaller sizes.

How To Measure Adjustable Feet:

When measuring Adjustable Feet, it is important to have a good idea of the key requirements that will enhance the day-to-day performance. Also, it is important to hold a consideration for weight capabilities. Outlined within the image below are the most important parts to consider when measuring up your Adjustable Feet.

1. Base Diameter: The Base Diameter is essential for stabilising and supporting the weight of the object. The larger the base, the better the level of stabilisation.

To find the base diameter of the foot, you should measure the size across the base as labelled within the diagram.

2. Thread Length: Thread Length is important for the height adjustment and installation of these feet. A longer thread will provide more upwards height than a shorter one.

The thread length of an adjustable foot is often the distance between the stud and bolt. The stud is the part labelled ‘thread size’. The bolt is the section where the thread joins the base.

3. Thread Size: Thread size is a key factor for supporting the weight of an object. It is also important for thread compatibility, as the thread must match the type that it is being screwed into.

To find the metric thread size of a foot, you should start by measuring the diameter across the thread. This can be done by putting the ruler against the stud of the adjustable foot (labelled thread size in diagram) and taking the measurement in millimetres.

Weight Guide:

This is where they are tested up to a particular level, proving beneficial for heavy uses where an idea of their performance is key. Our table below shows the weight ratings of our Weight Rated Feet.

What's Available For Adjustable Feet?

Our range of Adjustable Feet covers a huge number of options, from all-in-one solutions to heavy duty machinery feet. To get a better understanding and to prevent getting lost when matching up to your requirements, we have split up some of the main variants below.

Being some of the most common, these are regularly cheaper than their counterpartsFixed Threaded foot with adjustable thread example image.

Articulating (Levelling):
Articulating type Adjustable Feet (also known as Levelling Feet) are unique. They allow for up to 8° of articulation from standard. This enables their use with uneven surfaces that aren’t completely flat.

Tilting Feet come with a ball joint connection between the base and the thread. This allows for up to 20° of angled movement. Tilting type Adjustable Feet are regularly used with uneven flooring. They are also used with applications that have varying heights.

Weight Rated:
Weight Rated Feet are some of the most heavy duty offerings that we supply, each one being tested up to a certain weight rating to give you peace of mind. Each foot is fortified and built to easily sustain weight. This makes them ideal for use with machinery and conveyors.Weight Rated Threaded Feet with Adjustable base example image
