Kep Nuts feature a star washer that locks down on the heavy-duty aluminum structural elements for added strength to any TETRIX® robot design.


Prototyping a TETRIX® robot will never be the same – these rivets make trying out different designs quick and easy. Instead of the tedious tightening of nuts and bolts to assemble a prototype, just pop in these nylon rivets and insert the locking pin. The pin makes the rivet’s end flare out to secure the connection of TETRIX structural elements. And they are easily removed and reused.
