Countersunk Head Sentinel Screws have a unique head which can only be turned one way, meaning that once they have been securely tightened they are very difficult to remove.
Installed using a standard crosshead or Pozi driver, they are quick to install with both screwdrivers and power drivers and are a popular choice for installers and large volume applications.
The sentinel drive offers medium security resistance against vandals and thieves at a relatively low cost.
It is an adaptation of the original Nettlefolds Pozi Drive, designed to provide a secure and permanent fixing, and can be used in high volume. With high resistance to cam-out, these screws are the preferred choice for applications requiring high volume, labour intensive work.
Available in Zinc plated from Fastenright, with thread sizes from M4 to M6 and lengths ranging from 12mm to 40mm.
