What are Metric 5 Lobe Pin Security Countersunk Machine Screws?

5 Lobe Pin Security Countersunk Machine Screws are a type of tamper proof screw designed to provide a secure anti theft fastening solution. Unlike Torx Security screws, which feature a 6 lobe pin drive, this type of screw features a 5-Lobe Pin Security Drive, designed to be fastened using a specialist Security 5 Lobe Pin Drive Bit. As this is a less common drive type, it is more difficult for members of the general public to acquire, aiding the enhanced security of the fastener.

Featuring a Countersunk head, this type of anti theft screw is suitable for fastening applications where a flush finish is required for the screw head to fit within the housing material.
