Security Machine Screws
One of the largest ranges of security machine screws available in the UK, with an extensive choice of thread diameters and lengths available from stock now.
Security machine screws are suitable for use in pre tapped holes or with a nut, and are mainly stocked in a metric thread (with imperial threads also available). We stock both permanent and reusable security screws, with both medium and high security options available and a range of head types.
Matching security barrel nuts are also available for security screws such as the 6 Lobe Pin TX or 2-Hole security screws (pig nose screws or snake eye screws).
