SPANNER SCREW WRENCHES

Drilled trusshead spanner screw.
A special wrench is required to remove the drilled trusshead spanner screws which hold the handles on GI and FN spadegrips. The possibilities are endless. I show two GI wrenches and several home made ones.

A serviceable tool can be made easily by drilling two holes in a small piece of bar stock, and then screwing in two self-tapping screws, then backing the screws out and grinding the threads off the part that comes in contact with the bolt head.

I made a simple spanner wrench by threading the shank and tapped the handle & base. I used two short sections of a jeweler's file handle for the pins. Then I welded the whole thing for good measure.

This is easy to make, and the best design, as it allows for variations in hole centers. This is the wrench I settled on. Drawings link at right.

I was looking at a golf shoe cleat wrench one day and realized it was the perfect design for a spanner screw wrench. The pins are removable and replaceable. Too bad the cleat wrench is too small. I made this one from stuff laying around my shop. The overall length is 5".
