Turning the screw on crime with our range of time and labour saving security screws

The need to safeguard against theft, vandalism and tampering is an increasingly essential part of many design specifications. To counter these threats, we are constantly keeping one step ahead of the intruder by manufacturing a comprehensive range of vandal and tamper resistant fixings and fasteners which have a varied range of uses.

To make installation of our security screws easier and faster, our range includes a wide range of time and labour saving self-tapping, self-drilling and thread forming screws. We offer an expansive range of self-tapping screws stocked as standard in A2 stainless steel; going from 2.9mm up to 6.3mm in diameter from as short as 13mm up to 100mm long. Our self-tappers are available in all our most popular security drives from the 6-Lobe Pin to the more specialised and unique Solok™ range.

For fixing sheet metal to wood and other steel construction, we have also developed a range of self drillers equipped with our 6-Lobe Pin security drive. Drilling tips provide a fast and easy application eliminating the need to pre-drill and the 6-Lobe Pin (pin Torx style drive) is great for higher torque applications.

We have also developed a specialised thread forming screw (Power6™) ideal for automotive and fencing applications. This tri-Lobular self-threading screw eliminates the need for nuts, reducing labour costs & installation time. The Power6™ Security Screws also feature a unique shaped 6-Lobe Pin drive, providing a higher level of security.
