Original Bosch part 1610190058 — stop disc (thin stop/washer) designed for the GSH-series demolition hammers.

This is the original Bosch stop disc used to locate and limit the hammer/piston assembly inside the tool. It’s a flat, precision-formed steel stop washer that sits in the internal hammer mechanism and replaces a worn or damaged disc so the tool restores correct impact timing and travel.

Fits examples from the GSH 16-28 / GSH 16-30 — including GSH 16‑28 (types 3 611 C35 000) and several GSH 16‑30 variants (e.g. type 3611C35100, 3611C35180, 3611C351P0). Check your tool’s parts diagram to confirm this exact part number for your type.

Supplied as a single genuine Bosch replacement part (1 610 190 058). Ideal when the original stop disc is cracked, deformed or lost — install in place of the old washer to restore correct hammer function.
