Why this part matters
This nut clamps the tool/bit retainer and spring in place; a worn or missing nut will allow play in the tool holder or prevent the bit from locking properly. Replacing the nut restores correct retention and alignment so the tool works safely and as designed.
Fitment note
If you’re replacing the retainer/holder or spring assembly (for example Makita tool‑retainer 331132-5 / spring 231281-7 shown in parts diagrams), this M8 hex nut is the specified fastener. Check your tool’s parts breakdown or parts list to confirm the same part number and position in the diagram before installation.
(Does not include the retainer or spring — sold as the single nut, Makita part 252046-4.)
