Pin Pentagon Button Security Machine Screw

Pin Pentagon Security Machine Screws with Button Head

These tamper resistant, button head security machine screws offer a high level of security at an acceptable cost.

The Pentagon design of the drive is intended to keep the likes of torx-pin, hex-pin and other tamper resistant bits out, as well as standard shop purchased security bits. We will only sell a security bit if you have purchased the screws from us as well.

Often used in high-value applications like securing infrastructure and electronics that are in open areas. There are examples of these Pin Pentagon security machine screws being used to secure tablets and computers in public kiosks, protecting property as universities, and in government infrastructure.

It has a highly positive recess, which makes the drive incredibly user-friendly and reduces wobble.

Available from Fastenright in a range of sizes and lengths, both Metric and Imperial.
