The Tekno RC TKR1227 is a set of M4x9mm flat washers (10-pack) used across many Tekno RC builds for load distribution and secure mounting. These washers are designed to spread clamping force under screw heads, helping prevent pull-through, reduce stress on plastic or composite parts, and maintain consistent alignment in high-vibration areas of the vehicle. They are commonly used in suspension mounts, chassis assemblies, and drivetrain hardware on platforms like the EB, NB, ET, SCT, and MT series. Made to Tekno’s precise tolerances, they are a standard maintenance and rebuild item for keeping hardware secure and reliable under racing or bashing conditions.
