Genuine Makita Torsion Spring (part no. 231679-8) — a small, precisely wound torsion return spring manufactured from hardened spring steel that restores the correct return tension for switch/lever and guard-latch mechanisms in Makita angle grinders and rod/steel cutters.
Fits (examples): DGA454, DGA456, DGA504, DGA506, DGA511, DGA512, DGA513, DGA514 and DSC250/DSC251 series (listed in Makita parts diagrams and spare-parts catalogs).
Why this part matters: when the original spring is worn, bent or broken the switch feel, safety lock and guard release can become loose or unreliable — replacing it returns crisp lever action and safe, repeatable function. The 231679-8 is supplied individually and is straightforward to fit with basic hand tools; it’s the correct choice when looking through Makita spare parts for a direct, original Makita replacement to get your tool operating like new.
