Frequently Asked Questions
- What does 5/8″-11 mean in grinder nuts?
It refers to the thread size on the flange nuts that thread onto the grinder’s arbor. Most common grinders use this size, but some Milwaukee models may differ. - Do I need inner and outer flange nuts?
Yes. Inner nuts grip the wheel, while outer nuts provide a secure lock; many kits include both to accommodate wheel replacements and lock nut removal. - Will these kits fit all 4.5″, 5″, and 7″ grinders?
Most kits target 4-1/2″, 5″, and 7″ grinders with 5/8″-11 shafts. Always confirm your model’s shaft threading and any protrusions before ordering. - Are these parts OEM or aftermarket?
Most products listed are aftermarket components intended to replace worn or missing parts. Verify fitment against your model’s requirements. - What should I do if a nut doesn’t fit?
Double-check the shaft threading and verify there are no shaft-end bosses that interfere with fitment. If uncertain, contact the seller for compatibility confirmation.
