Original Hitachi seal‑lock hex‑socket screw — part number 987860. This is a metric M6 × 6 mm hex‑socket fastener (6 mm thread diameter, 6 mm length) with a seal‑lock head designed for a driven Allen‑key installation; sold as the single replacement screw.
What it replaces on the tool: common use is as a small fastening/locking screw in blade guards, covers and pivot assemblies on Hitachi / HiKOKI mitre and circular saws. Example models where 987860 appears in parts lists include C10FSB, C10FSH and C3607DRA, and it also shows up in exploded parts for several compact saw models (e.g., C8FSHE). These listings make it a direct-fit replacement when your tool’s original hex‑socket screw is lost or damaged.
Other notes: part number (HKK987860 / HIT‑987860), size : M6×6 specification. This genuine Hitachi screw is a small but essential item among Hitachi parts for keeping blade housings and guards secure.
If you need a single replacement that matches factory thread and length, the 987860 M6×6 seal‑lock hex‑socket screw is the correct compact fix for the model examples above.
