Sentinel Security Screws with Countersunk Head
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 from stock in zinc plate, with a range of sizes and materials to order as specials.
