Makita EXT E-RING JIS U-6J HR2630 - 257336-0

Makita 257336-0 — Stop Ring (External E‑type, U‑6). This genuine Makita external stop ring (listed as “STOP RING EXT U‑6”) is the small E‑clip that secures a shaft or pin in the hammer/drill assembly, preventing axial movement of gears or piston components during operation.

Made from hardened spring steel with a corrosion‑resistant finish for reliable retention under vibration and repeated service, it matches the original Makita profile and tension required by the tool’s parts diagram.

Size: U‑6 (fits the 6 mm shaft/groove used in the specified hammer/drill assemblies); typical DIN‑6799 E‑clip dimensions for this nominal size give a clip thickness of about 0.7 mm and the standard outer/profile to match the groove.

Fits a range of Makita rotary‑hammer and hammer‑drill models — examples include HR2630, HR2610/HR2611F series, BHR242 and DHR242 / DHR243 / DHR280 / DHR281 models listed in Makita parts diagrams. If you’re repairing a Makita hammer this is the original Makita stop ring you’ll need; it’s a common item in Makita spare parts listings.

Compact and simple to fit: replace the damaged or missing ring with the original Makita 257336-0 to restore correct axial retention and safe operation of the tool.
