Hitachi 955-479 Spare Part - Retaining Ring (e-type) For D6 Shaft
Original Hitachi retaining ring, part no. 955479 — an E‑style (three‑lug) external retaining ring designed to secure the D6 drive/feeder shaft in roofing coil nailers.
This small but critical clip is used on the Metabo HPT / HiKoki / Hitachi NV45AC 1‑3/4" light‑duty roofing coil nailer to hold components on the D6 shaft in place while the tool cycles.
The “D6” designation corresponds to a nominal 6 mm groove/groove‑diameter; typical E‑style rings for that size have a groove diameter around 6.0 mm and a ring thickness of roughly 0.68–0.70 mm, so it fits 6 mm shaft applications.
This exact retaining ring is listed as the replacement for Hitachi/Metabo HPT / HiKoki (and Tanaka) nailer assemblies, so it’s the straightforward part to swap when the original clip has worn or popped off.
If you just need a single replacement to get a nailer back to service, this genuine Hitachi retaining ring is a low‑cost, direct-fit solution — a small essential in any collection of parts for power tools.
