Nylon Insert Nuts
Commonly referred to as a Nyloc nut, these hexagonal shaped nuts have a nylon insert which prevents the nut from coming loose due to vibration.
Shear Nuts
These cone shaped nuts feature a hexagonal gripping point which snaps off when the maximum torque has been reached, leaving just the cone-shaped nut which is difficult to remove.
Wing Nuts
