Types of Security Screws

Security Screws come in two type; the Perma fix range and releasable screws which require a special matching screwdriver to do them up or undo them.

 

The Perma fix range of security screws are one way screws which once done up cannot be undone, wheras releasable security screws can be done up and undone, but only with a special matching security screwdriver or driver bit.

 

Two types of Perma-fix security screws are available;

Clutch Head security screws are a slot headed type of screw which can be done up with a standard flat bladed screwdiver, but once installed, cannot be undone as the reverse drive face of the screw head is milled away so the screwdriver simply slips off the screw.

Posidrive type Sentinel security screws can be installed with a standard philips type screwdriver

 

Releasable security screws;

These screws can be done up and undone again if required, but only by using a special matching security screwdriver or driver bit.
