Hitachi 311-959 Spare Part - Special Screw (left Hand) M6x23
Genuine Hitachi part 311959 — Special left‑hand screw (M6 × 23 mm) designed to secure the drill’s chuck and internal spindle assemblies. The screw is a left‑hand (reverse) M6 thread, 23 mm long, made to the original Hitachi specification so it engages correctly where a reverse-thread fastener is required.
Fits a range of Hitachi / Hikoki cordless and corded drills — examples include DV18DL / DV18DJL, DS14DBL, DS18DBL, D10VF and D13VF. Use this part when the original screw is stripped, lost or damaged to restore correct chuck retention.
Compact and economical replacement for repairs: M6 thread diameter, 23 mm shaft length, left‑hand thread—simple to swap back into place and get your tool working again. As a genuine Hitachi item, it’s the direct match for the tool’s specified fastener and is listed in parts diagrams under the same number. This is a commonly requested power tool parts item for maintaining dependable chuck retention.
Note: tighten to the original torque setting where known and re‑check chuck security after installation.
