FAQ
Are split lock washers reusable?
Split lock washers can sometimes be reused if they are not deformed, but for critical applications replacing them is recommended to ensure full locking effectiveness.
What does 8.8 grade mean?
8.8 is a tensile strength grade for alloy steel fasteners and indicates high tensile strength suitable for demanding applications.
Will these washers prevent all fastener loosening?
They substantially reduce loosening due to vibration but for extremely high-vibration or safety-critical assemblies use additional locking methods such as threadlocker, locknuts, or safety-wiring.
