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.
3M™ Friction Shims come in four grades:
The selection of the right grade depends on the highest surface roughness (Rz) or highest average surface finish (Ra) of the two mating counterpart surfaces (transversal to direction of machining).
In general, Grade 55 is recommended for e-coated and painted substrates. See the technical data sheet for additional details.
Guard critical joints against high shear force
Reinforce bolted connections in automotive chassis and axles, aircraft structures and more. 3M™ Friction Shims help strengthen and secure joints, enabling them to withstand up to 5× higher shear force. By helping protect against joint fatigue, loosening and failure, they allow designs to support significantly higher loads without the need to change parts or component sizes. 3M friction shims work with a variety of dissimilar mating counterparts: aluminum, carbon steel, stainless steel, cast iron, titanium, magnesium and more. Special grades ideal for e-coated steel are also available.
Boost torque transfer and downsize components
Optimize power density in your ICEs, eMotors, wind turbines and other applications. 3M™ Friction Shims are a proven, cost-effective means to boost torque transfer by up to 5× while reducing the number and size of certain components. In automotive applications, they help powertrains handle high torque from powerful electrified engines and can also maximize power density in smaller, more compact engines. In wind energy applications, they help downsize turbine components by allowing for smaller and lighter bolts and fasteners. 3M friction shims can even help strengthen torsional joints in precision robotics systems such as wrists, end-effectors and grippers.
