Episode Notes:

You will need:

  • Set of hollow ground screwdriver bits
  • Or individual hollow ground screwdrivers

Many gun manufacturers use screws uncommon to hardware stores. Guard against damaging the screws while working on your firearm.

It is often difficult to replace damaged screws, but sometimes they can be repaired. So save those screws!

Screwdriver bits that are too short, too narrow and too thin will damage screw heads.

Head Repair
You will need:

  • Pin vise
  • Ball peen hammer with polished face
  • Slot file
  • Sandpaper

It is possible to repair screw heads that are not too badly damaged by gently hammering the raised burrs flat, filing the slot and polishing the head.

  1. Chuck the screw into a pin vise to protect the threads.
  2. Clamp the pin vise in jaws of a large vise to hold it while it is being worked on.
  3. Peen the screw head until all burrs are flattened out.
  4. Clean up the slot with a slot file.
  5. Polish head surface smooth with 240 grit sandpaper.
  6. Polish in original direction and grit.
