Original DeWalt 326573-01 — Wing screw / thumb screw, black, M6 × 17 mm. This genuine DeWalt wing screw (wing knob) is a molded black plastic thumb screw with a metal thread insert designed for hand-tightening edge guides, fences and small clamps on routers, planers and similar tools.

Fits many DeWalt and Black & Decker models — common examples include DW621, DW626, DW677, DW678, DW680, DW614/DW615 series, DW6913, DW788 and DCS777/DCS778 — so it’s a direct replacement when the original thumb screw is missing or worn.

Quick details: M6 thread, 17 mm length (M6 × 17 mm), black finish, installs by hand and secures guides or small fixtures without tools. Ideal as a spare when you need a genuine DeWalt part to get your tool back to working order.

Note: confirm the part number against your tool’s parts diagram or manual to ensure fit for your specific type/version.
