Security Machine Screws - Pin Hex Countersunk

About our Hex Countersunk Security Screws

Often abbreviated to Hex Head, Hexagon Heads are found on most common bolts and set screws, this is a six-sided head that requires a socket or spanner to fasten. You can also use a tool called a nut spinner or nut driver to fasten a hexagon head – this is effectively a screwdriver with a socket head instead of a blade or Posi drive end.

Countersunk bolts are used when a flush finish is required, with no part of the screw head protruding above the level of the item being secured.

Our Countersunk Security Machine Screws all have a pin located in the middle of the drive to prevent removal with standard tools, making them excellent tamper-proof screws. We stock a choice of Pin Hexagon or Pin Resistorx 6 lobe drive, and both are available in a stainless-steel finish.
