Countersunk security wood screws

Designed to fix to wooden surfaces, we recommend creating a pilot hole before inserting the wood screw.

The Sentinel drive offers medium security resistance against vandals and thieves at a relatively low cost.  An adaptation of the original Nettlefolds ‘Pozi’ drive, designed to provide a secure and permanent fixing, and can be used in high volume, inserted with a power tool.

With high resistance to cam-out, Sentinel screws are a preferred choice for applications requiring high volume, labour intensive work.

Sentinel countersunk wood screws can be used with security Wave Nuts, Shear Nuts, Kinmar Reusable Nuts, Kinmar Permanent Nuts, 4-Hole Nuts or Pin Torx Barrel Nuts for added security.
