Original DeWalt 145344-00 — Blade / shaft bolt (special screw) for circular saws. This genuine DeWalt replacement is the threaded “special” screw used to secure the blade / clamp and spindle assembly on many DeWalt circular saw models, restoring the clamping point that holds the blade and outer clamp in place during use.

Fits DeWalt models include D23700 , DCS383N , DCS570 , DCS572 , DCS573 , DCS575 and DCS576 — commonly listed in parts diagrams as part 145344-00.

Specifics: listed in parts breakdowns as a “screw / bolt (special),” with recorded dimensions in the ~16–20 mm range across major suppliers’ technical listings (roughly 16–20 mm diameter and about 20 mm overall length, depending on the exact application and type variant). Use this original DeWalt part when you need the correct fit and thread for the blade clamp and spindle interface.

This is one of the DeWalt parts you’ll want if you’re replacing a stripped or missing blade bolt — a simple swap that gets the saw back to safe, reliable operation. It’s a standard item among parts for power tools used on circular saw blade assemblies.
