Genuine DeWalt compression spring N411486 — a small, original DeWalt coil spring used in the contact/actuator assembly of DeWalt DCN-series brad/concrete nailers. It’s the direct replacement spring that restores the contact-trip / firing return action on affected nailer models.

Fits DeWalt models in the DCN6xx / DCN68x families — for example DCN650, DCN660 (including DCN660B / DCN660D1/D2 variations), DCN661, DCN680 (including DCN680B / DCN680D1) and related DCN68x units. Use this part when the nailer’s contact trip, detent or trigger return feels weak, sticky, or has failed to spring back.

Product details: genuine DeWalt steel compression spring, compact helical design meant to sit in the nose/actuator area and provide consistent return force. Listed item dimensions on product listings are very small (approx. 12.7 mm length × 2.5 mm height × 5.1 mm width as shown in catalog/spec entries), making it suitable for the tight assemblies in these nailers. Sold individually.

Replace a tired or broken N411486 to restore crisp, reliable contact-trip operation and extend the service life of your DeWalt DCN-series nailer.
