20090097943 | Distorted nut with an arrow shaped end - Normally, when assembling trucks to a skateboard, a screw and a nut are used to mount it to the skateboard. The assembly requires two tools, a screw driver and socket wrench, which are used to tighten the skate trucks to the board. The purpose of my invention is to eliminate the use of the socket wrench. Lockdown is a specially designed nut with an arrow like end that serves to keep the nut from rotating when tightening the skate trucks to the board, which eliminates the socket wrench. This is how the process works, the nut with the aid of its arrow like end, butts up against the truck and prevents it from rotating. Normally with a regular nut, you would need a socket wrench to keep the nut from rotating. With lockdown the process eliminates the need for a socket wrench thereby making the installation faster and efficient. | 04-16-2009 |
