*edit* It requires a Spanner bit. =) There's a whole set. Swell. =)


I have included a picture. Not sure what it is... I'm only familiar with the basics (philips, slotted, hex, tamper-proof hex, torx, allen, etc).


So what's this thing, and where do I get the bit necessary?

Thank you for any information!

It's one of many types of "tamper proof" fasteners.

Honestly,I wouldn't waste my time looking for the "correct" driver to fit that.

If you have a flat screwdriver of the appropriate width just grind out the center to leave just the two points.If it's bigger than it looks(>.375in dia) then you might have to look for the correct tool.

If you are going to want to remove it again, after you get it out, use a slot file or a hacksaw blade to cut a slot across the holes so it can be removed/replaced with an ordinary screw driver.

You might be able to use a pair of c-clip pliers, or maybe look at the Grainger catalog.

You could make one.Carefully measure the diameter of the holes and the distance between them. Get hardened pins of the right diameter[sometimes the shank of drill bits are the easiest way. Drill holes and insert pins into suitable material .Now you have a spanner !!

Some shotguns use a bushing that is made like that to hold the firing pin in from the front .
Brownells offers an adjustable tool for the two pin ones,part number
590-017-002 ($24.95)
Hope this helps!

it looks like the same screw we use to hold bathroom stall doors on. try your local industrial fastener store. we use the screw to keep people from messing up the bathroom doors. just a hint

Yeppers, That's a spanner all right.

Usually screws like that are only used in places where the manufacturer thinks they'll never need to be removed. They're usually not torqued in too tightly unless they've been Loc-Tited.

I made a simpler spanner wrench the other day: grind down the tips of cheap needlenose plies. Works pretty good!

What is the difference between this one and a Truss Head Bolt? (which is what i thought the pictured bolt was)
