How often are you bending them Neil? Ive slightly bent my front screws once, and the rear ones only after a huge crash, and the car has had a lot of use now.

If they come loose during a race then they become more prone to bendages, so do use thread lock and keep checking them. i check mine after each race, its quick to do with an L shaped allen key - no need to take wheels off.
