Genuine Bosch striker pin (part no. 1617000491) — a precision, heat‑treated impact pin that transfers the hammer action inside Bosch demolition hammers.

Designed as a direct-fit replacement for Bosch GSH series breakers (commonly used in GSH 16-28 and GSH 16-30 machines), this original Bosch component restores consistent impact performance when the striker has worn, mushroomed or fractured.

The pin is precision‑machined and hardened for long life and smooth mating with the roller/striker assembly; it’s supplied as the single replacement striker/bolt used in the hammer’s impact train (also referenced as 1.617.000.491 in parts lists). As one of the Bosch power tool parts that keep heavy‑duty demolition tools working reliably, it’s the exact part you need to bring the hammering action back to spec.

Simple to install by disassembling the striker housing and swapping the worn pin for the new one — replaces the failed pin to eliminate blow‑loss, sticking or irregular impacts and gets your tool back to full force.
