Conical Serrated Lock Washers Set, 400Pcs, M6 Heavy Duty ✔️ External tooth lock washers; hardened steel core; reusable

These conical serrated lock washers are heavy-duty fasteners designed to grip shafts securely in automotive, machinery, and DIY projects. The inward-pointing teeth bite into the shaft surface when compressed, creating a positive lock that resists vibration and rotation, while the hardened core preserves tooth geometry through repeated install cycles.

✅ M6 size fits standard shafts
✅ Hardened steel core maintains tooth geometry under high clamping force
✅ Internal teeth grip shaft surfaces for secure lock
✅ Reusable: removable and re-installable without losing grip

💡 What is a handy method to choose the right conical serrated lock washer size for a specific shaft diameter?

Choosing the right size keeps contact tight and vibration under control.

- Inner diameter should match shaft size for snug contact - Teeth bite into shaft surface to resist loosening from vibration - Hardened steel core maintains bite geometry over many cycles - Reusable design supports maintenance and adjustments ✝️
