It's really a pleasure to work with the included balldriver; the very latest in Balldriver technology, "THE PROHOLD(tm) BUTTON". They lock in place for a true non-slip application. And, you can put the screw on the Balldriver first, and then place it where it goes! This is a major improvement over the "old style".

This screw has become a widely used fastener in model building. It really does have a million uses! You can mount your servos, but also great for canopies, cowls, hatches, landing gear straps and much more. It has a self-contained washer that completely covers the servo grommets and acts as a normal washer on other applications. It has a deep non-slip socket head that takes a 5/64 hex (Allen wrench) or Ball Driver.
We carry the five most popular sizes. With them, you can do most any job. One of our newer sizes is the #2x5/16". This short length screw works great for such things as cowls, canopies, etc. We are often attaching a thin piece of plastic or fiberglass and simply don't need a longer screw which might stick out into the fuselage and poke a wire or fuel tank! This short screw is extremely popular and works great for a host of miscellaneous jobs.
