Genuine Bosch threaded ring, part number 3613461500 (also listed as 3 613 461 500). This hardened, precision‑machined retaining ring threads into the tool housing to lock and secure the hammer/grinder nose and internal components — an exact replacement when the existing ring is stripped, cracked or no longer holds assemblies reliably.

Compatible with a range of Bosch demolition hammers and heavy grinders — examples include GSH 11 E (GSH11E), GSH 10 C (GSH10C), GBH 11 DE (GBH11DE) and several Bosch 11xx series breakers/hammer models such as 11316EVS, 11311EVS, 11223EVS and 11245EVS. Confirm your tool’s exploded parts diagram or model tag matches the part number before installing.

Supplied as the single threaded ring replacement (no extra hardware). It’s the original Bosch spare — fit, finish and tolerances match original specifications so you can restore the tool’s proper retention function quickly and get back to work.
