Step 1: Thoroughly clean the box in question with a little fresh water to remove any sand or grit and make sure the screw hole and work area are clean and dry.
Step 2: When dry, use masking tape to cover the screw hole on the inside cavity of the box so the resin doesn’t run out the bottom of the hole.
Step 3: Prepare the epoxy by following the instructions on the back of the package. Fill the screw hole with Five Minute epoxy. NOTE: Leave a little void at the top of the screw hole, to allow the drill to be started easier. Allow the epoxy to dry for a few hours.
Step 4: Use the #21 drill bit to drill a hole through the epoxy following angle of the original screw hole.
Step 5: Now use the 10-24 tap to re-tap the drilled hole following the angle of the original screw hole.
Step 6: Screw in the screw and check for tightness, then go for a surf!
