Hobie's kayak screw-in deck fasteners allow you to customize your boat with the fasteners of your choice wherever a molded-in-thread is present on the kayak (each Hobie model has several positions available). 
 
The Hobie screw-in fittings can be easily removed and replaced using the tool. However, a good pair of long nose pliers is often a pretty good surrogate. Padeye style fittings can be easily removed by being levered through the padeye with a screwdriver.
