Snake eyes [screws] have two holes in the head.
These are for removing [spanner screws] which are basically one inch bits.
We also have a screwdriver that these snap into.
You slide it in, push it forward, lock it in, and your bit is in there.
This particular screw is heavily used. This is a #10 x 3/4" screw with a truss head.
So this is a truss head security screw. This screw is used on license plates.
So I have here a truss head spanner snake eye screw that I showed you before.
And this is the driver bit in this screwdriver. I have a plate here, and this is the most common screw used for this.
A lot of guys like this; they are made out of stainless steel. They look nice on your car.
Especially if you have a historic car or a corvette. Corvette guys like this.
Everybody asks, "What size screws do I need to hold my license plate on? I want to use those snake eye spanner screws."
And there it is, right there.
We do get some complaints from buyers saying they snapped the bits.
In several situations, you could snap the bit, however, if you use it properly, you will not snap the bit.
Some applications were you would possibly snap a bit:
One, going into a hard wood without predrilling.
If you go into hardwood, and you don't predrill, and you just try to drive the sheet metal screw into the wood,
chances are you will snap the bit, or you'll snap the screw. Either one could happen.
I can drive this screw into this softwood, which is a 2x4, with no issues of snapping a bit and remove it.
I'm gonna demonstrate that.
Another way to snap a bit would be running it into a material
and on the backend there's some metal the screw cannot go through and you get an immediate stop
in the screw that will snap the bit.
There's only two teeth on one of these spanner bit drivers.
Of course they can snap. It's not a perfect world with these types of bits.
Not like a torx driver of something along those lines where they are very hard to strip out or snap.
So I'm gonna demonstrate, right now, installing this.
It's always important to make sure your bit is square to the screw and the wood so you have positive contact.
Put your hand on the back of the drill and you'll see I'm just driving it in with no problem.
And it'll just suck it in.
And now I just snapped it.
And why did I snap it? I snapped it because the head is countersunk and the screw came to a stopping point.
So those who are snapping bits, that would give you a reason they are snapping.
So you can see here, the bit is snapped. SO I can't use that bit anymore.
If you're driving a screw in a natural piece of wood, and not over-torquing it,
you should have no problems with the bits.
It doesn't matter the quality of the bit. You will still snap the bit in that type of situation.
