Original Bosch stop disc (part no. 1617000461 / 1 617 000 461) — a precision metal thrust/stop washer designed for the percussion assembly of Bosch rotary hammers.

This compact stop disc provides the positive stopping and positioning of the striker/rotating components so the hammer maintains correct impact timing and doesn’t over-rotate; it’s built from a durable, machined metal to withstand repeated service.

Direct-fit for several Bosch rotary-hammer models including GBH 5-38 D (type 0 611 240 003), GBH 5-40 DE (type 0 611 241 703) and related GBH 500 / GBH 5400 variants — confirm your tool’s 10‑digit type number on the nameplate to ensure compatibility.

Easy to swap in during basic service, this original Bosch stop disc restores correct percussion stop action and alignment without machining or modification. Bosch power tool parts like this are manufactured to the same fit and tolerance used in production.
