How do you fix a stripped fin screw if the plastic box is stripped?
Option A:

Step 1: 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 the Where 3. 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 (10/32) tap for Futures or (10-24 x 5/16) tap for FCS to re-tap the drilled hole following the angle of the original screw hole.
Step 6: Screw in screw and check for tightness, then go for a surf!

Option B:
Step 1: 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: Mix up some 5 min. epoxy and apply a sufficient amount onto the original screw (spray some PAM onto the screw before applying the glue).

Step 4: Now put it back in the hole and wait for it to dry.
Step 5: When it dries completely, remove /un-screw in normal fashion and sand off any remains on the top of the plug, then go for a surf!

How do you fix a stripped fin screw if the Stainless Steel set screw is stripped?
Option A:
Step 1: Get a set screw removal tool like Datool or an easy out reverse thread extractor. Datool can be found here.

Step 2: Follow instructions that came with the tool. (It works like a screw with backwards thread)

OptionB:
Step 1: Clean the screw hole.

Step 2: Take a fin key and dab some super glue or epoxy on the end of the key and set it in the screw hole. Wait til it hardens.
Step 3: Now you should be able to unscrew it.

Note: Grime (sand, wax, leftover resin, sanding residue, etc.) can get shoved down in the screw hole. This doesn’t allow the hex key to go all the way down in the hole and therefore the key isn’t biting the screw properly. A lot of people don’t know this, but if you look toward the bottom of the shaft of an FCS key, about 1/8″ up from the bottom, on one of the six hex surfaces there is a line / notch. This notch is there for a reason and is set at the exact depth where the key should be all the way in the screw. This serves as a guage to see if your key is going all the way in or if maybe there is debris in the bottom of the hole not letting the key catch properly. If there is debris down there, use a needle or a push pin to scrape the grime out.
