  Servo Mounting Screws (Self Tapping) Socket Head/Washer Head, Zinc Plated
            ("The Screw with a Million Uses")

 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 all the popular sizes. With them, you can do most any job. Both the #2x7/16" and the #2x9/16" work well for most servo applications. The #2x9/16" is the most popular size, and is the size of Du-Bro and other popular brands. The #2x7/16" is very versatile; it's slightly shorter length makes it suitable for many applications, in addition to servo mounting, it can be used on cowls, canopies, hatches, etc.

Also, we are exclusive dealers of the #2x5/16:
The shorter #2x5/16" works great for attaching cowls, canopies, etc. on small and mid-size planes. It's a great all purpose short screw for many jobs, including for small servo installation. As model builders, we are often working with a thin piece of plastic, fiberglass or wood and we just don't need a longer screw. Very handy in the shop and at the field!

We also carry the #3's when a slightly larger screw is needed. The #3's will fit standard servo grommets and are often used with today's more powerful servos or just added security with standard servos. They are also great for many other tasks, such as landing gear straps, etc.
