Well Nuts

When fixing to loose or granular substrates a well nut is one of the best fixings to consider, made from rubber with a nut at the base these fixings expand as you tighten them, conforming to the irregular shape of the hole. These fixings are ideal for fastening speed bumps to tarmac and concrete. These fixings come in a wide range of sizes to suit all types of applications.

About Well Nuts

Using the correct type of fixing is essential to its long-term success, especially in areas with a lot of moisture and/or vibration. Well nuts (also known by the brand name RAWLNUTS) are a versatile type of fixing designed to fasten components to thin, wet or brittle materials like sheet metal, plastic, and fibreglass. With the help of their rubber (or neoprene) sleeve, these nuts are designed to expand when tightened, providing a secure, waterproof and vibration-resistant hold. This makes them ideal for installation in environments that need a fixing with water resistance, and vibration damping, that provides a strong hold.

Their design allows for easy installation and removal, making them suitable for situations that require frequent maintenance or adjustments. Well nuts are especially useful where traditional fixings might cause stress or damage. They provide a watertight seal, which is essential for applications exposed to moisture or where a tight seal is needed to prevent leaks.

These rubber expansion nuts are perfect for professionals and DIY enthusiasts in the marine, automotive, and electronics industries, among other industries.

Getting The Best Rubber Expansion Nuts For Your Needs

Before choosing the best expansion well nuts for your project, consider the following factors to ensure it meets your needs:

Material

Because of their use case, well nuts must be made from strong, durable rubber or neoprene in order to perform well.

Load Capacity

Choosing the right load capacity is essential for supporting the fixture's weight. We provide load ratings with each of our different sizes and types of well nuts, so be sure to choose one with a higher load capacity than your project's requirements.

Removability and Reusability

How often will your nut need to be removed and reinstalled? One of the key advantages of rawlnuts is their ability to be removed and reused. Choose one that offers durability and ease of reuse without compromising the strength of the fixing.

Base Material

What kind of base material are you installing your rawlnut into? Different nuts are designed for, or work better, in different materials like tarmac, metals or fibreglass; so make sure the rawl nut you choose is compatible with the base material!

Length

How long does your well nut need to be? The length should be enough to create a secure hold between the two components, without sticking out too much from the surface.
