servo screws have the same thread diameter (approx 2.1mm), length (approx 16mm), and pitch as the well known Servo manufacturers screws, but have an allen key head. This makes installation into deep fuselages so much easier - the screw is a snug fit onto the end of a 2mm A/F allen key and will usually stay attached as you reach into the fuselage or any other tight space. No more tearing your hair out as you loose the servo screws in the fuselage ! No more annoying dents in the wing where you slipped when installing the aileron servo. We just know you will wish you'd used them for years !
These screws are also ideal for other applications such as securing cowls and canopies etc.
