Hex Driver 7/64 ball for Split Jaw rail clamps – 6 inch hex driver SJP-10706
Split Jaw clamps are held together with socket screws requiring a 7/64 inch hex driver. For your convenience, you can order a high quality ball style hex driver of the correct size here. They work great and keep you from over tightening the screws. Ball style drivers allow you to work off set from the axis of the screw, as shown here. This makes the installation MUCH easier than using non-ball style Allen wrenches.
The 6″ screwdriver style hex driver is useful for most hand tightening situations.
