Starboard M5 Torx Slot Box Screw

Slot box fin screw for counter bored M5 inserts, like those used by Starboard for the angled screws which secure the thruster fins into place.

The standard M5 x 15mm TX30 screw supplied by Starboard, is often not long enough to secure these fins propperly, especially after considerable use or for non standard fins, so a longer screw is often needed.

These screws solve the problem!

They have a Torx TX25 Pan head, so you will need a different screwdriver to the Starboard one (we often have these availabe to buy if you have not already got one) 

Available as M5 x 18mm or M5 x 20mm, so they are 3 or 5mm longer than standard, securely holding all the fins we have tried.
