Genuine Bosch 1609B03777 — set screw for Bosch slide/compound mitre saws. This is the original Bosch replacement set screw used to secure slide/carriage and housing components on compatible Bosch GCM-series saws; it’s a compact, internal-hex (Allen-style) grub/set screw designed to match the factory fit and tolerances.

Example models it commonly fits: Bosch GCM 8 SDE, GCM 8 SJL, GCM 800 SJ, GCM 10 GDJ and GCM 18V-216 (Verify your 10 digit product code to confirm fit).

Why this part matters: it’s the exact Bosch part number for the threaded fastener shown in the saw’s exploded diagrams , so replacing a stripped, broken or missing screw with the 1609B03777 restores the original locking function and alignment.

Notes: listed as the Bosch set screw (part 1609B03777) in Bosch power tool parts listings and repair diagrams; confirm the part reference number from your saw’s exploded parts diagram before installation to ensure correct placement.
