Genuine Bosch thread‑forming screw — part no. 1613490013 — engineered to replace the original fastener used inside Bosch rotary hammers.

This small, thread‑forming tap screw is designed to cut and form its own mating threads in the tool’s housing or internal sheet‑metal inserts, restoring secure assembly and alignment of internal components.

Commonly used in Bosch GBH 4‑32 DFR series rotary hammers (GBH 4‑32 DFR / GBH4DFR and closely related 3 611 C32xx variants), so it’s a direct replacement when that model shows a stripped or missing fastening point.

A straightforward, original Bosch part that makes repairs simple — exactly the kind of small item you look for among parts for power tools when you need the correct fitting fastener.
