How do you stop joint slippage without adding more bolts?
As EV battery packs grow heavier, bolted joints face increasing shear forces. Slippage under load can compromise crash safety, increase NVH and drive overengineered fastening strategies that add weight, cost and complexity.
Boost joint friction by up to 5X and reduce fasteners without changing your bolts, materials or adhesives.
In a new whitepaper, we share insights from nearly two dozen real-world battery pack designs, showing how 3M™ Friction Shims can reduce bolt count, simplify assembly and improve load performance while supporting more compact EV designs.
Already proven in over 300 million vehicles, they’re trusted by OEMs and Tier 1s for reliable fixation across aluminium, steel and composites.
Inside the whitepaper:
- How a 10-bolt system with 3M™ Friction Shims held up to 47G
- Design patterns and fastener trends from 19 OEM and Tier 1 battery packs
- How one system went from 39 bolts to just 10 with no loss in strength
- Why joints slip under load and how to fix it
- How to boost fixation performance without redesigning your system

3M™ Friction Shims are an innovative solution designed to enhance the performance and reliability of mechanical bolted joint connections. These shims are coated with a unique blend of hard particles (nickel-phosphorus and diamond particles) that significantly increase the coefficient of friction between surfaces. This results in improved torque transmission and load-bearing capacity, making them ideal for high-stress applications in automotive, aerospace, and industrial sectors. By using 3M™ Friction Shims, engineers can achieve more compact and lightweight designs without compromising on strength or safety. Trust 3M’s expertise and advanced materials to deliver superior performance and durability in your most demanding projects.
