Hitachi 308386 — Machine screw M5 × 16 mm with captive spring washer (black finish). This genuine Hitachi replacement screw is a precision M5 threaded pan-head fastener with an attached spring (split) washer designed to secure housings, guards and accessory mounts on small grinders and masonry saws.
Built to the original Hitachi fit and finish, it restores proper clamping and electrical contact where the factory fastener has been lost or stripped—ideal when you need a reliable, like-for-like repair part. Use this when checking Hitachi spare parts for grinders and cutters.
Example models this Hitachi screw fits include : grinders (G10SD2, G10SF3, G10SN2, G10SQ2, G10SR, G10SK, G10SG, G13SR / G13SR2 / G13SR3 / G13SS grinders, and small masonry saws such as CM5SB. Confirm the part number against your tool’s parts diagram to ensure fit.
Simple, direct replacement — same threads, same length (16 mm), same spring-washer configuration so you can finish your repair and get the tool back to work.
