Does “Universal” mean every angle grinder?

These accessories cover many angle grinders, but the name is not a fit guarantee. Match the shaft and hardware sizes, check guard clearance, and follow the grinder and wheel manufacturers’ mounting instructions. Older or unusual shaft sizes may require different hardware.
