We are currently experiencing substantial delays with Hitachi/HiKOKI and Metabo spare parts due to the two brands merging warehouse. At this moment in time we are unable to provide confirmed delivery dates on out of stock parts, for any urgent requirements please contact us prior to ordering.
Hitachi part 877371 — M5 nylon-insert lock nut (nylon nut) designed to secure small linkages and fastenings on Hitachi/HiKOKI nailers, staplers and similar tools.
Details: genuine Hitachi replacement part, metric M5 thread (nylon locking insert for vibration resistance), used where a low-profile locking nut is needed on a pushing lever or small assembly. Ideal when you need a direct-match original Hitachi spare parts item to restore proper fit and function.
Example models this part is used on (non‑exhaustive): NR83A / NR83AA, NT65A2, N5008AC2 and NV90AB2 — check your tool’s exploded parts diagram to confirm placement. This small but critical piece is a common item among Hitachi power tool parts and will get a worn or missing nut back to original specification.
