3M™ Friction Shims consist of a nickel-coated steel substrate with partially embedded diamond particles. When placed between two mating surfaces in a bolted connection and applied with pressure, the diamonds “bite” into each surface to create a microform fit. This allows for a coefficient of static friction up to 5× greater than in a conventional bolted connection.
Higher Torque. Same Bolt Connection In automotive, wind energy and many other industries, there is a general trend towards compact, lightweight designs with maximum power density — and high reliability. However, in order to transfer high loads in friction joints such as shaft-collar or bolt connections, the size or number of components typically needs to be increased. 3M™ Friction Shims offer a proven and cost-effective alternative: by increasing the coefficient of friction between components, they allow transmission of up to 4x higher torques — without requiring modification to the joint design.
