M6 x 30mm 5-Lobe Pin Button Head Security Screws - A4 Stainless Steel - Box of 100 5-Lobe Pin Button Head Security Screws, successor to the Resistorx, feature a domed head and an internal 5-lobe pin socket drive instead of 6 providing a higher level of security. The 5-Lobe Pin security drive offers an improved tamper resistance compared to the more commonly available 6-Lobe Pin drive; as the tooling is more specialised and as a result harder for members of the general public to get hold of. The internal 5-lobe pin drive adds a level of security to these screws, as a standard torx bit & 6-lobe pin cannot be inserted. These security screws must instead be paired with a security drill bit, resulting in a tamper-proof fastening.
