A T-slot bolt is a fastener used to connect parts together in a T-slot extrusion. T-slot extrusions are structural aluminium profiles with a "T" shaped cross-section with a groove on the top and bottom. The T-slot bolt is designed to fit into this groove, allowing it to be securely fastened to the extrusion.

One of the main advantages of T-slot bolts is their versatility. They can be used to connect a wide range of parts, including panels, brackets, and other structural elements. This makes them a popular choice for use in a variety of applications, such as machine frames, workstations, and display systems.

T-slot bolts are also easy to install and remove. They can be easily tightened or loosened using a standard hex key, allowing users to quickly and easily adjust the connection between parts.

In addition to their versatility and ease of use, T-slot bolts also offer a high level of strength and stability. They can hold up under heavy loads, making them suitable for use in various demanding applications.

Several types of T-slot bolts are available, including standard T-slot bolts, stud T-slot bolts, and step T-slot bolts. Standard T-slot bolts are the most common type and are used to fasten parts together in a simple, straightforward manner. Stud T-slot bolts are similar to standard T-slot bolts but have a longer thread length, allowing them to be used in applications where a longer fastener is needed. Step T-slot bolts are designed to fit into extrusions with different groove sizes, making them suitable for use in a variety of different T-slot systems.
