Genuine Bosch straight pin 1613100032 — a precision dowel-style pin used inside Bosch rotary-hammer assemblies to locate and secure internal components.

This small, press-fit straight pin is found on exploded parts diagrams where it holds ratchet/striker/gear elements in place in the hammer mechanism, so replacing a worn or damaged pin restores correct alignment and movement.

Common fitment examples reported for part 1613100032 include Bosch GBH 2‑20 D / GBH 18V‑20 / GBH 18V‑21 / GBH 180‑LI (RHH180) and PBH/TBH series rotary hammers (examples vary by region—check your model number).

If your tool’s internal pin is bent, sheared or missing, this original Bosch replacement part installs where the factory pin sat and is the exact match engineers specify — a straightforward way to get the hammer mechanism running true again. Bosch power tool parts.
