Grub screws, also known as slot screws, are types of screws with an internal head that is slightly smaller than the external head. As a result, a notch is created on the external head, which allows for the slot of a screwdriver or Allen key to fit in.

Grub screws are commonly used for fixturing and clamping. They are often used when precise adjustments are needed or when you’re working in confined spaces. For example, you can use grub screws to secure an object in place, thereby preventing it from turning or moving.

When using grub screws, the hole into which they are placed must be slightly larger than the diameter of the screw itself. This is because grub screws are designed to expand when tightened, which helps them to stay firmly in place.

Grub screws come in a variety of materials and sizes, and can be used in a wide range of applications. They are used in metalworking, electronics, automotive and aerospace industries. Some examples include:

- Securing threaded inserts

- Preventing shafts from rotating

- Adjusting the tension of a pulley

- Connecting threaded rods

Grub screws are incredibly versatile and are used in a wide range of applications. When using grub screws, it’s important to ensure that the screw is of the correct size, material and head type. This will ensure that the screw is strong enough to hold the components securely, while also preventing any damage to the materials being secured.
