Small Flat Blade Screwdriver

[Bmp]

Need a good screw driver to remove a slotted screw space for blade is 7mm x .5 mm

Trying to remove a trigger guard on a very expensive shotgun. I cannot have it mar the head or slip. How are small screwdrivers labeled. Google is not showing much.

Love the forum very interesting stuff. I hope I can contribute in the future.

You need some Grace gunsmith screwdrivers.

Look up "hollow ground" screwdrivers. Gun screws are designed for these. https://www.amazon.com/dp/B07YVJ2YPR/?tag=atomicindus08-20

Make sure you use something that fits properly for guns smithing like Grace.

That’s a very narrow screw slot.

You could try a Brownells “Magna Tip” bit. I haven’t checked but I suspect there will be something very close.

Personally, I’d get a regular 7mm screwdriver, or 5/16 if you have to go “next size up” and simply grind it down.

If you don’t have a grinder it might be worth getting a cheapo one. Alternatively a stone and much patience...! Standard thickness for that size driver is probably about 1mm, so there’s a fair bit of thinning down to do.

Another vote for Grace screwdrivers. You definitely want to use a gunsmithing screwdriver.

Forster is another good option. They specialize in gunsmithing tools. . .

I would go with a Chapman gunsmithing driver kit. They have a wide range of bits that are hollow ground, and designed for exactly what you are doing.

They are expensive, and there may be bits you don't think you'll need, but you'll find that they will come in handy for future projects.

For a less expensive option, there are a number of kits made by Wheeler, that have plenty of bits.

I would not use a regular screwdriver on that screw. The tip, as others have said, must be hollow ground, to prevent damage to the screw.

If I have a critical screw slot that needs a solid fit then I usually use a slightly bigger screwdriver and grind the tip with a Dremel w/emery wheel to where it's a perfect snug fit. That's also what the watch and clock guys do.
