Strengthen static joints and maximize friction torque transmission in torsional joints with 3M™ Friction Shims.
3M™ Friction Shims for optimal reliability and performance
-
Strengthen critical joints, increase power density and enable more compact and lightweight designs. 3M™ Friction Shims are a simple, efficient and highly effective solution to help guard against high shear forces in static joints and maximize torque transfer in torsional joints.
From automotive chassis and powertrains to precision robotics to wind energy and aerospace applications, you can boost coefficients of static friction by up to 5× while downsizing components by using smaller and lighter bolts and fasteners. Strengthen and streamline your design with 3M.

How do they work? Watch a 3M™ Friction Shims demo with one of our expert application engineers.
3M™ Friction Shims consist of a nickel-coated steel substrate with partially embedded diamond particles. When placed between two components in a bolted connection – such as a battery mount or e-coated frame – the diamonds “bite” into each surface to create a microform fit. This allows for a static coefficient of friction up to 5x greater than in a conventional joint bolt connection.
3M™ Friction Shims are ultra-thin, compact, highly reproducible and tailored to customers’ precise design requirements. They help substantially strengthen and stabilizes critical joints and provide long-term reliability by protecting against fatigue, loosening and failure of bolted connections.
Industry applications
-
Protect static bolted joints against shear forces and maximize friction torque transmission in torsional joints for increased power density in modern car chassis and axles. Enable support of heavy, highly sophisticated components, accommodate high friction torque in powerful engines and eMotors with 3M™ Friction Shims. Design flexibility, vehicle lightweighting and NVH reduction are just a few additional benefits.
-
Wind PowerReduce component size and weight while guarding against high vibration to enhance safety buffers with 3M™ Friction Shims. Ideal for wrists, end-effectors, bolt connections, links, grippers and other precision systems in which low inertia and quick, nimble movements in multiple directions are essential. 3M™ Frictions Shims fit narrow engineering tolerances and can be used as design-in or drop-in solutions.

Wind Energy
Maximize friction torque transmission in wind turbines while minimizing component size and weight with 3M™ Friction Shims. Whether it’s flanges, shaft-collar connections or other joints or bolted connections, you can downsize components by combining smaller bolts and fasteners with lightweight, powerful 3M friction shims. They help you meet restrictive size requirements, facilitate transport and reduce costs.
-
AerospaceGuard against shear and torsional forces under the toughest conditions on Earth – and beyond. 3M™ Friction Shims help secure critical bolted joints in aircraft structures and engines, helping protect against loosening, fatigue, slippage and failure of bolted connections. In satellite systems, 3M™ Friction Shims can be used in the satellite bus, rotary actuators, robotic arms, antenna systems and more.
