Benefits for professionals
These 8.8-grade split lock washers are designed to provide long-term, dependable performance under vibration, temperature changes, and moisture. Compared to standard washers, the split lock design keeps a constant clamping force that reduces fastener loosening — critical for automotive, HVAC, and machinery applications where safety and uptime matter.
How to use split lock washers — quick tips
- Place the washer directly under the nut (or bolt head if specified) so the split edge bites into the mating surface.
- Do not reuse deformed washers — replace when flattened or damaged.
- Pair with the correct grade and size of nut/bolt for optimum performance.
- For high-corrosion environments, consider additional corrosion protection such as zinc plating or stainless alternatives.
Storage & organization
The kit comes with a compact, transparent case with labeled compartments that hold sizes separately and make retrieval quick on the job. Labeling reduces downtime and helps you track inventory at a glance — a small organizational improvement that multiplies productivity in busy workshops.
