The SS8 Spring Lock Washers in the M6 size are designed for engineers, mechanics, and DIY enthusiasts who need to secure threaded fasteners against vibration-induced loosening. By exerting continuous radial force, these washers maintain tension in critical assemblies, ensuring long-term reliability in automotive, industrial, and electronic applications. While they provide excellent locking capability, users should note that they are intended for permanent or semi-permanent installations and may mark the surface of softer materials when tightened.

While they can be removed, their spring force may degrade over time. For critical safety applications, it is best practice to use a new washer.
The SS8 series features a durable silver finish suitable for standard mechanical applications.
A flat washer is optional but recommended if you are fastening against soft materials to prevent the spring washer from scarring the surface.
No, these are specific to M6 hardware. You must use the size that matches your bolt diameter.
These are designed for general industrial and automotive use. Please consult structural engineering specifications if your application involves extreme thermal expansion.
Ensure the washer is fully compressed during installation. If the washer is already flattened, it has lost its spring force and must be replaced.
The square edges can mark soft surfaces. Use a flat washer between the substrate and the spring washer if surface finish is a priority.
To achieve optimal performance, ensure that the M6 washer is paired specifically with M6 bolts. Place the washer onto the bolt shank before threading it through your material. Tighten the assembly until the washer is fully compressed, but be mindful not to over-torque if you are working with soft metals like aluminum, as the square edges of the washer may bite into the surface.
Regular inspections are recommended in high-vibration machinery; if the washer loses its spring tension after years of service, it should be replaced. These washers do not require special lubrication, but they should be kept in a dry environment to maintain their finish.
