Genuine DeWalt screw — part 577359-00. Precision Torx-head fastener used to secure the blade-clamp assembly in reciprocating / jig saws. The screw is a Torx (T10) security-style fastener and is self‑tapping (it cuts the mounting threads as installed); common metric size listed for this part is approximately 3 × 12 mm. Many repairs use two screws to reattach the clamp (the clamp assembly this fastens is DeWalt part 377375-00SV).

Fits (examples): Black & Decker/DeWalt reciprocating and jig saws such as PHS550B, PHS550G, SC500, SC500G and SC500K — used as the mounting screws for the blade clamp on those models. Note: a security Torx driver is required and using a threadlocker on installation is commonly recommended.
