The 21mmx13mmx7mm M8 T Nut with Roll Ball Elastic design is a specific type of T-nut commonly used with 4040 aluminum extrusion profiles. It is designed to fit into the T-slots of the profile and provide a secure connection for various components.

The T-nut has dimensions of 21mm in length, 13mm in width, and 7mm in height. It is typically made of durable materials such as steel or another strong alloy to ensure stability and longevity.

One side of the T-nut features a threaded M8 hole, allowing for easy attachment of bolts, screws, or other M8-sized fasteners. The other side is equipped with roll ball elastic nuts, which act as a detent mechanism.

The roll ball elastic nuts are designed to provide a secure fit within the T-slot of the 4040 extrusion profile. These nuts have a spring-loaded ball bearing mechanism that allows for easy insertion and adjustment along the T-slot without the need for disassembly. The spring-loaded balls engage with the profile's T-slot, providing a secure and reliable connection.

The 21mmx13mmx7mm M8 T Nut with Roll Ball Elastic design is specifically tailored for use with 4040 aluminum extrusion profiles, which have a cross-sectional dimension of 40mm by 40mm. This ensures compatibility and a proper fit within the T-slot of the profile.

Overall, this T-nut provides a reliable and efficient method for attaching components to 4040 aluminum extrusion profiles. Its dimensions, M8 thread, and roll ball elastic nut mechanism make it suitable for various applications that require secure and adjustable connections within the 4040 profile system.

The M8 T Nut you mentioned is a specific type of nut used in various applications, particularly in the construction of aluminum extrusion profiles like the 4040 series. Here are the specifications for the M8 T Nut:

• Size: The M8 T Nut has a size of 21mm x 13mm x 7mm. This refers to the overall dimensions of the nut, including its length, width, and height.

• Material: The nut is typically made of steel or stainless steel, providing strength and durability.

• Thread Size: The M8 T Nut has an M8 thread size. This means that it has a metric coarse thread with a diameter of 8mm.
