Makita 344492-6 Spare Part - PLATE HR3000C/4000C/5001C/3540

Genuine Makita replacement plate (part no. 344492-6). This small stamped steel plate fits under the side-grip assembly and works with the square-neck side-handle bolt and grip spring to secure the auxiliary handle on Makita SDS‑max rotary hammers — it’s the metal “plate” shown in the HR4002 parts breakdown and is the same item listed for other Makita rotary‑hammer models.

Example models that use this part (common listings): HR4002, HR4000C/HR4040 series, HR3000C, HR4500C/HR4511C, HR5001C and certain HR52xx series rotary hammers. These model matches are shown in Makita parts diagrams and multiple spare‑parts catalogs that list 344492-6 as the plate for the side-handle/side-grip assembly.

Sold as the single original Makita plate (part no. 344492-6). If your side handle or side-grip base is loose, damaged, or missing this plate, replacing it restores the correct fitment and handle retention so you can safely use the tool again.
