Hitachi 949-776 Spare Part - Roll Pin D3x10 (10 Pcs.)

Hitachi part 949-776 — Roll pin, D 3 × 10 mm (rolled/spring pin) designed to secure shafts and small linkages inside Hitachi pneumatic nailers and similar tools. Packaged as a 10-piece set, each pin measures approximately 3 mm diameter by 10 mm long, making it a direct replacement for the roll pin used in several Hitachi nailer assemblies.

Fits examples: NV45AB2 (roofing coil nailer), NR90AC3 (full‑head framing nailer), NV65AC (coil pallet nailer), NV83A2 (full round‑head coil nailer) and several NT-series gas/finish nailers — commonly listed as compatible with Hitachi part 949-776. These small but critical power tool parts are what keep trigger/driver and feed components aligned and retained during operation.

If a single worn or broken roll pin is preventing your nailer from operating smoothly, this exact D3×10 roll pin (Hitachi 949-776) restores the original retention fit without modifying the tool.
