Original Bosch replacement cylindrical-head screw — part no. 2603413034. This is the genuine Bosch cylinder-head (socket) mounting screw used in the assembly of several Bosch PST-series jigsaws; it appears in Bosch power tool parts diagrams as the fastening screw for the housing/base area.

What you get: a single original Bosch cylindrical-head (socket) screw (listed as one unit in the parts diagram) sized for the jigsaw’s body/mounting points so it restores the correct fit and alignment when a lost or damaged screw is replaced.

Example models this part fits (verify your tools 10 digit product code to confirm fit): Bosch PST 650; Bosch PST 900 PEL (type 3603CA0200) and PST 1000 PEL / PST 9500 PEL.

Notes for installation: this is the original Bosch fastener shown on PST Jigsaw models (check the part position on your model’s diagram), so it installs directly where the original screw was used. If you need a direct replacement fastener that matches the tool’s original specification and head style, this is the correct Bosch part to restore the original assembly.
