When a Phillips is not a Phillips!

Step 28: Philips/Cross Tamperproof

The Tamperproof Screw Company was founded in the late 1970s when George Friedman developed the Phillips Pin-Head security screw. It consists of a traditional Phillips drive with a tamper-resistant pin added for security. Prevents unauthorized tampering with the screws. The Philips/Cross tamperproof profile has the same properties as the classic Philips/Cross; the difference is that the tool has a hole located in the tip and the screw head has a small central pin.

Advantages and Disadvantages of Phillips Pin-Head

Theft Proof fasteners are virtually impossible to remove without the matching driver. These screws are easy to drive & remove with matching tool. Also cannot be removed with Phillips Screwdriver. Available in sizes #1, 2, 3.

I won't reveal it but the pin head screw takes only three seconds to bypass with a screw driver and something else very common. The screw designer screwed up.

YES. This technique will work even when the screw is recessed 1" under the surface. Even if the screw is hardened. Here's what they can do to solve this. The center stud should be cone shape, not cylindrical. They need geniuses, someone like the creator of the rubiks cube or criminals be consulted to make this kinds of standards.

[masterochicken]

Yeah. I would definitely put criminals and the creator of the rubiks cube in the same category.

I usually take a Dremel to the security post and grind it down. You don't have to grind it all out, just enough so that your tool kind find purchase and torque.
