Discover more about the Metric 5 Lobe Pin Security Countersunk Machine Screws range.

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.

Materials

This type of security screw is manufactured from Marine A4-70 Stainless Steel (316) as standard and avalible in a wide range of materials to suit your project requirements.

Upgrade your 5 Love Pin Security Countersunk Machine Screws with pre-applied thread-locking. Secure with AccuLock Threadlocker, reinforce with Anu-Lok 180, or go high-performance with Precote 80. For a premium touch, AccuBlack chemical blackening minimises reflections and delivers a sleek, professional finish.

Metric 5-Lobe Pin Security Countersunk Screws

Accu stocks 5-Lobe Pin Security Countersunk Screws in metric thread sizes M3 to M8 and in lengths ranging from 6mm to 40mm.
