Frequent Questions & Answers
What are lock nuts for?
What size RC nuts do I need?
Match the nut thread to your screws, commonly M3 or M4. Check your car’s manual for the sizes it uses.
Steel or aluminium nuts?
Steel is strong for high-load spots. Aluminium is lighter and colourful for low-stress areas, but softer, so keep it off critical joints.
