Makita 142235-8 — genuine Makita "Nut Complete" designed to secure the sprocket / side-cover assembly on compatible Makita chainsaws.
Fits (examples): UC3551A (350 mm), UC3541A, UC4041A and UC4051A (400 mm electric models), and Makita cordless DUC353 — it's the same numbered nut called out in the parts diagrams for those models.
What you’re buying: the original Makita 142235-8 complete nut assembly — a drop‑in replacement called out in the sprocket cover / sprocket‑cover kit (it holds the cover and chain‑tension components in place and replaces worn or stripped fasteners so the cover seats correctly). Because it’s the original Makita part number, it matches the factory thread / profile and fitment used on the listed models.
If your sprocket cover won't clamp solidly or the nut threads have rounded, this genuine Makita nut restores the proper fit and function quickly and cleanly.
