Tamper Proof Screws, Nuts and Matching Security Bits
Tamper Proof Security Screws, or Tamper Resistant Screws, are distinguished by having an unconventional drive, making tampering with the screw more difficult, if not impossible without the matching driver or bit. Security Screws are used for securing materials from being tampered with in public areas, such as gutters, license plates, grills, and hardware in jails, schools, boats and cars. Tamper proof fasteners are also commonly used in food prep and processing areas, particularly in stainless steel. You will often see security screws used in bathroom stalls, toilet partitions and other public locations. Security screws in this selection are grade 18-8 or higher stainless steel, which prevents rusting and is corrosion resistant. Security fasteners are engineered in different styles, however they all share the same principle that removal of the fastener is impossible (or at least very hard!) without the corresponding bit.

Bob: Welcome back to Albany County Fasteners - Fasteners 101. I'm Bob and today we're going to talk about security screws.
I have an array of security screws here, in different heads and styles and drives. We're going to review these now and I also have tools to install these screws. So, first I'm going to start off with what I call "snake eyes" (spanners) which have two holes in the head. So, you can't put a screwdriver in this screw to drive it or remove it. This particular screw is heavily used, this is a #10, 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 for most historic cars. It's stainless steel. It's mostly used for outdoors.
I have here a one-way pan head sheet metal screw. This screw is typically used on applications where you do not want to have the screw backed off. You can only put this on with a regular screwdriver. As you can see here, I'll just turn it for you in my hands. However, if you went to take it off you cannot take it off. The reverse has a slope to it and doesn't allow you to back the screw off. If you put pliers on it, lock jaw pliers, if they can grab it (and spin) in the right direction, sure you can probably remove this. But it's going to take some time to back that screw off.
The next security screw I have is sheet metal. This is a Torx with a pin-in. I believe that this is a round head and this particular screw is widely used in a lot of applications. You'll find these used on bathroom partitions, cubicles and urinal separating dividers. So that's the most widely used screw as far as security screws go. There is a bit for each one of these. Here I have a screwdriver that has the hole in the center of the screwdriver, so it can fit in there. If you took a regular Torx driver without that hole, you're never going to get this in here.
I have also these snake eye sheet metal screws; pan head. This one in particular is a pan head security screw. They come in flat head also, with the snake eyes. Then we have, these are all sheet metal, we also have the Torx, or 6-lobe as some people call them, with the pin in, in flathead and oval head. They come in different varieties of heads for different applications. We also have the snake eyes in machine screws. You can see them here, this is an oval head machine screw and it comes in a flat head machine screw (also). We also have the 6-lobe, or the Torx head, with the pin in, in machine screws.
Lastly, we also have the security screws in self-drillers, with a self-drilling type three (TEK) point. These are 410 stainless steel, and they come in two head types: the flat head or the pan head.
These are for removing; which are basically one-inch bits. We also have a screwdriver that you snap it into. You just slide it in, push it forward, lock it in and your bit is in there. These are very good tools, we'll go a little further into them in a few minutes, these are available. They come in fixed. This you can pop bits in and out of, which is awesome you just need one and you just keep buying these bits (many drive styles available). We also have a t-handle security (screwdriver). All of these have the hole in the center for the security bit to fit into the screw.
This is a tri-nut. This is so you can put on the machine screw. I don't know if this is the right size, but we'll see, no this is not the right size. Let's see maybe this one...No, I don't have the right screw here for it, but this is a tri-nut, it's a security nut. It has, this is the driver for it, three grooves and you can see it has three slots That's why they call it a Tri-Nut it has three: Tri. This is your driver you put it into a ratchet and it falls right in there and then you just drive it into place. These are used a lot in TV installations in hotels where they'll make sure that the TV cannot be removed from the wall. So they use these tri-groove nuts and they also use these sheet metal screws with the six-lobe Torx pin in. Those are used a lot in hotels to prevent the customers from removing the equipment.
I also have these power bits which can also be used in this screwdriver. These are great bits. We also stock these VEGA security drive sets. For the guy that's always working with security screws, this is a great set. This is a 32-piece VEGA set; it's s2 modified steel, CNC machine tips. It has a convenient belt clip which is really nice. You can just put this on your belt and keep it with you, if you're a regular guy that works with security screws. This is a nice set. It has a driver in it which you can snap into you drill; your battery drill, if you like. You have a whole selection of snake-eye bits to Torx security bits. It closes very nicely. It's a very nice set.
Then I have this other security, industrial security drive bit set. This is a 50-piece set. Let me pop this open. This set has almost everything you are going to need for security screws and Torx. The nice thing about Torx security screws is that you can use Torx security bits in regular Torx screws. But you can't use a regular Torx bit in a security screw because you need that hole for the pin. These are the two sets that we have that are available on our website for purchase. I wanted to show you today these different screws I'm also going to go and demonstrate the snake eye license plate bit.
I'm going to show you that these are the typical screws that are used on license plates. So, I have here a truss head spanner snake eye screw. That is a screw that I demonstrated to you, and this is the driver bit in this screwdriver. I have a plate here, this is the most common screw used in this application. A lot of guys like this. They're made of stainless steel and they look nice on your car, especially if you have a historic car. Or a Corvette, Corvette guys like this.
Everybody asks "what size screw do I need for my license plate? To hold my license plate on? I want to use those snake-eye, or spanner, screws." [A size 10 is what you need] And there it is right there.
Looks nice. Everybody likes it. It's fastened on there; it's not going anywhere. There you go. You got to get one of these kits. If you deal with security screws, you have to have this. This is a must have kit. It has everything that you're going to need. This is the 32-piece kit, sorry I had it upside down and this is the 50-piece kit.
Both kits are must haves if you are dealing with security screws.
