Makita 252159-1 — Hex Nut (M6)

A genuine Makita M6 hex nut (part no. 252159-1) designed to replace the small but critical fastening nut used on a range of Makita circular saws and related tools.

What it is and why it matters

This machined hex nut secures M6 bolts on blade guards, housings and accessory mounts—replacing a worn or missing nut restores proper clamping and eliminates play or vibration that can cause noise or premature wear. The item is sold individually and matches Makita’s original specification for fit and finish.

Example models it fits

Common compatible models reported by parts databases include BSS500 / BSS501, BCS550, DCS550 / DCS552, 5621D / 5621RD and some PJ7000/plate-joiner variants—check the part diagram for your exact model to confirm placement.

Short practical notes

Simple to install with a standard wrench on the corresponding M6 stud; a correct replacement from Makita keeps factory tolerances and helps maintain safe operation. If you’re ordering Makita spare parts for a repair, this original Makita nut is a direct-fit quick fix to get your tool back in service.
