Original Makita 231965-7 — Ring Spring 10: a small, heat‑treated spring‑steel retaining ring that secures the bit sleeve / spindle and anvil assembly in compact Makita impact drivers and cordless driver/drill designs.
Marked "10" (nominal metric size), this circlip‑style ring provides the preload and axial retention needed for repeat impact and rotation without deforming.
Examples of models where 231965-7 appears in Makita parts diagrams include TD022D / DF030D / DF010DSP / DF012D / BTD062 / BFT041R / DF010D / TD091D and BTS130
Supplied as the original Makita replacement part, 231965-7 restores proper component retention and bit security so the tool runs reliably again — a small genuine Makita part worth keeping on hand when servicing your impact driver.
