These great little specialty tools are a must for all aircraft owners and mechanics as well. They are available in two sizes and will cover almost all GA aircraft. They are precision laser cut from 4130 chrome moly aircraft grade steel and heat treated to a 42 rockwell hardness so they are very strong. They then get zinc plated to prevent corrosion and provide many years of service. These are .135? thick so you can rotate axle nuts and test fit the keepers or cotter pins in place. These tools weigh 4 oz. each. |
