Genuine Bosch part 2917760187 — a slotted spring pin / clamping sleeve used to lock and align internal components in demolition hammers and breakers.

This part is specified as a DIN 1481 slotted spring pin with nominal dimensions 8 mm × 55 mm (designation 8×55).

Fits a number of Bosch breaker/demolition-hammer models — commonly listed for Bosch 11304 and 11335 / 11335K , Bosch BH2760VC / BH2770VCD, and heavy-duty hammers such as the GSH27 / GSH27VC and USH27.

If the original pin is bent, sheared, or worn, replacing it with this genuine Bosch 2917760187 restores the factory fit and the correct alignment of the hammer’s striker / retaining assemblies so the tool operates reliably again.
