Description & Specs

The Makita 5in inner lock nut is a replacement grinder part that sits behind the disc on compatible angle grinders. Made from durable metal, it pairs with the outer lock nut to hold grinding and cutting discs securely in place.

  • Size: 5in (suits 115mm and 125mm grinders)
  • Type: Inner lock nut
  • Colour: Black
  • Model: 224554-5

The inner lock nut, or backing flange, supports the disc against the grinder spindle so the outer lock nut can clamp it firmly. Its low-collar design suits a range of grinders, making it a handy spare to keep on hand if the original is lost or worn. When fitting, follow your grinder's instructions for the correct orientation of the nut.

Really impressed with the Makita 5in — it looks and feels more premium than the price suggests. Delivery was quick and packaging kept everything safe. No issues at all.

Brilliant Aussie deal

Been buying Makita gear for years and this is one of their better ones. The Makita 5in quality is excellent — everything was included and setup took under 10 minutes. Had it at the door in Brisbane within 2 days. My son immediately claimed it for himself so I had to order another. 10 out of 10.

Worth every cent

Did a lot of comparison shopping before buying here and I have no regrets. Best price I found anywhere and delivery was fast — 3 days to Melbourne. Product feels genuinely premium, not cheap at all. Packaging was solid too, box arrived in perfect shape. Will be back for more.
