Makita 266283-4 Spare Part - HEX SOCKET HD BOLT M8X20 HS61

Genuine Makita 266283-4 — Hex socket head bolt (M8 x 20 mm), made to replace the blade/clamp fastening bolt on several Makita 7-1/4" circular saws. This is a direct-fit, original Makita replacement designed to restore secure blade clamping and proper alignment.

Key specs: metric thread M8 x 1.25 with a 20 mm thread length, head diameter ~18 mm and designed for a 6 mm hex (Allen) key — the same socket-head dimensions used on the saw’s clamp assembly. These specific dimensions make it a drop-in replacement when the original bolt is rounded or damaged.

Example models this part commonly fits: Makita 5007MGA / 5007MG / 5007NK (and related 5007-series circular saws; some listings also reference compatibility with nearby 5008-series variants). If your saw is a 5007-series, this is the bolt that secures the blade clamp assembly.

A simple, reliable fix — swap out the stripped or missing bolt with this genuine Makita spare to get accurate cutting performance back fast. Add this genuine Makita part to your selection of power tool parts when repairing a 5007-series saw.
