   • Determine which hole has the cross threaded or stripped screws.

   • Determine the size of the current thread. Threads are called out by the outer diameter, a dash, and then the thread count. For example, the tap shown is 1/4"-20".

   • The hole's outer diameter can be determined by measuring the width of the screw or bolt that goes into the hole.

   • The thread count can be determined by counting the number of threads in one inch of screw length.

   • Select the appropriate tap size.

   • Taps are sharp. Do not handle the teeth.

   • Install the tap into the tap handle (See photo).
