DeWalt 647776-00 Spare Part - BLADE BOLT

Genuine DeWalt blade bolt 647776-00 — direct replacement blade fastener your mitre/table saw needs to hold the blade securely on the arbor. This original DeWalt part is a steel blade bolt specified at M8 × 20 mm with left‑hand threads and a Torx T40 drive (note: some listings reference a hex‑drive variant on closely related bolts), designed to clamp the blade between the inner and outer flange washers for safe, vibration‑free cutting.

Fits many DeWalt chop and mitre saws and related combination/table saw models — common examples include DW712, DW713 (and DW713XPS), DW717/DW717XPS, DW718 (and DW718XPS), DWS780 / DWS780-type saws, DCS365 / DHS780, and table/combination models D27105, D27107, D27111–D27113. If your saw uses the same blade‑washer arrangement and M8 left‑hand bolt, this part restores correct clamping pressure and blade alignment.

Buy this original DeWalt replacement when your existing bolt is worn, rounded, lost, or stripped — it’s the small part that keeps the saw safe and accurate. This listing is for a single genuine DeWalt part; if you keep a couple of DeWalt parts on hand it saves downtime when changing blades.
