Hitachi 949-518 Spare Part - Roll Pin D3x18 (10 Pcs.)

Hitachi roll pin — part number 949518. Straight replacement roll (spring) pin, diameter 3.0 mm × length 18 mm, black-finish steel. It’s the small hardened split/roll pin that secures shafts and linkages inside many Hitachi / Metabo HPT / HiKoki power tools; sold commonly in packs of 10 for convenience.

Why this part matters: it’s a precision interference pin (rolled steel) that compresses slightly to lock into a 3 mm hole — exactly what you need if a pivot pin, stop or small shaft has worked loose or sheared. The 3 mm × 18 mm size is the correct direct replacement called out on Hitachi parts diagrams for several models.

Example models it fits (examples from Hitachi/Metabo parts lists):

- Metabo HPT / HiKoki / Hitachi C10RA and C10RA2 table saws (listed as Roll Pin D3×18, part 949518).

- Hitachi/Metabo nailer models such as NR83A2, NR83A2(S), NR83A3, NT50AE2 and NR90AD use the same D3×18 roll pin in their assemblies (listed under the same part reference).

What you get: a durable steel roll pin (3 × 18 mm), pre‑finished in black for corrosion resistance and a snug press fit. It’s the exact size called out in exploded parts diagrams, so it drops in where the original pin does and restores the original mechanical retention.

If your saw or nailer has a loose pivot or a missing small shaft pin, this is the direct, metric‑sized replacement part called out by Hitachi/Metabo parts diagrams — quick to fit with a punch and a hammer or press.
