Circular Saw Outer Clamp Flange Washer & Blade Bolt — For DeWalt DC390 / DC310KL / DCS391
Direct replacement outer clamp flange washer and blade retention bolt for DeWalt circular saws DC390, DC310KL, and DCS391. The outer flange washer and blade bolt work together to clamp the saw blade securely against the inner flange — distributing clamping force evenly across the blade bore to prevent blade wobble and ensure accurate, vibration-free cutting. Safety-critical components — replace immediately if worn or damaged.

Why Replace the Blade Clamp Washer & Bolt?
- Prevents blade wobble — worn washer or stretched bolt allows blade lateral movement; causes inaccurate cuts and vibration
- Safety critical — a loose blade is a serious safety hazard; replace worn components immediately
- Restores cutting accuracy — new clamp components restore blade concentricity and cutting precision
