4040 Series M8 T Slot Nuts Roll-in Spring - Spring Sheet Loaded Elastic Nuts (100 PCS) Carbon Steel for 4040 Series Aluminum Extrusion Profile Rail with 8mm Slot for 3D Printer & Sim Racing

Introducing our 4040 Series M8 T Slot Nuts with Roll-in Spring Sheet – a superior choice for precision and ease in your projects. Designed specifically for 4040 aluminum profiles, these nuts feature an 8mm slot and an M8 thread diameter, ensuring a perfect fit for your extrusion needs. Crafted from high-hardness carbon steel and coated with a nickel-plated finish, these nuts offer exceptional rust resistance and durability for long-lasting performance. The innovative spring sheet mechanism allows for effortless installation: simply insert the nut into the slot, twist with a screw, and watch as it securely locks into place with minimal effort.
