Original DeWalt 869245-00 — a genuine DeWalt hex blade screw used to secure the blade/guard assembly on many DeWalt mitre and circular saws.

Technical details: M8 × 1.25 thread pitch, 22 mm thread length, left‑hand thread, 6 mm internal hex (socket) drive; steel construction with a black finish. (Replaces part number 145344‑01 on some diagrams.)

Example compatible models (illustrative, check your model drawing): DWS771, DWS777, DWS778, DCS777 / DCS778, DW770, DW771, DW777 and DW717 /DWS779 mitre and combination saws — this fastener commonly appears on parts lists for those tools.
