Part features
12 mm diameter
Standard size for 0.3 kg Y-blades and lighter hammers on 105–145 cm mulchers.
Self-locking nut
A plastic insert in the nut prevents it from working loose under vibration — secure fastening without extra locking.
Consumable part
We recommend replacing it every time the blades are changed — a worn bolt can fail at high speed.
Operating safety
A badly fastened blade = risk of it flying off during work. Always use new bolts with newly fitted blades.
