Makita RING SPRING 35 HM1203/HM1213 - 233970-0

Makita 233970-0 — genuine Makita "Ring Spring 35". This is a metal ring-style retaining spring (nominal 35 mm size) used inside the impact/barrel assembly of Makita demolition hammers to hold internal components in place during piston travel.

Fits many Makita SDS‑max demolition hammers — for example HM1203C, HM1205C, HM1213C / HM1214C, HM002G.

Sold as the single ring spring shown in Makita parts diagrams; a direct factory replacement if the original retaining spring is damaged, lost, or worn.
