For competitive setups you need parts that deliver repeatable results. The 3RACING Aluminium M3 Flat Washer in 3.5mm black provides uniform seating under fasteners to help maintain consistent geometry between runs.
Machined-style aluminium washers provide a favourable strength to weight ratio and reduce local stress concentrations. Their surface finish helps resist light corrosion while keeping mass low for performance applications.
Use these washers when adjusting servo mounts, suspension linkages or thin bracketry where precise spacing and reliable clamping are required. Their slim outer diameter is suitable for tight clearances common in race builds.
Install washers flat and ensure mating surfaces are clean to avoid misalignment. For repeatable torque settings, use torque control and replace washers that show deformation after heavy use to preserve setup integrity.
