Button Head Security Screws
Button Head Sentinel Screws have a unique head which can only be turned clockwise; meaning that once they have been tightened securely, they cannot be removed without drilling out.
Installed using a standard crosshead or Pozi driver, sentinel security screws are quick to install with either power drivers or standard screwdrivers and are a popular choice amongst installers for large volume applications.
The drive of the screw offer 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.
With a high resistance to cam-out, they are the preferred choice in applications that require high volume, labour intensive work.
Available from stock as standard in zinc plate from M4 to M8, with other sizes and materials available to order, and specials made to order.
