Diamond Claw Flywheel Crank Flange Surface Lock Shim – Audi 2.7T



Diamond Claw® surface locks have successfully eliminated fretting (surface welding) in every application Shaftech customers have placed them in. With an installed thickness of .010″-.012″ a Diamond Claw® will not significantly alter assembly spacing.

Quality Materials
A Diamond Claw® is only as good as the sum of its parts. Diamond Claw® locks consist of precisely sized CBN (diamond) particles that are plated onto proprietary fatigue resistant steel. The uniformity of both diamond particle spacing and overall thickness insure complete contact across the entire Diamond Claw® surface. Diamonds with an exceptional hardness of 10,000 vickers are held within a plated matrix of 950 vickers. This combination of extreme hardness and toughness allow a Diamond Claw® to penetrate surfaces hardened to 65Hrc.
