Bristol Hex Wrench Set (For Radio Knobs)

Bristol Hex Wrench Set (For Radio Knobs)

The Bristol Tool Company also make good quality Hex Wrenches.  Using the incorrect tool on the small grub screws in aircraft radios will cause damage that costs much much more to put right than this set of wrenches would have cost in the first place.

This set will work for most avionics knobs and controls.  Please remember to check if it's a Hex or a Spline grub screw.  Use a suitable magnifier to look at the end of the screw, identify the correct tool from the picture below.  If it's a spline you need the SS-508 set.

Set comprises:

• 0.028"
• 0.035"
• 0.050"
• 1/16"
• 5/64"
• 3/32"
