Tri-drive micro profile head screws are tiny, ultra-thin high precision micro security screws. The three wing design ensures that the screws are easy to work with as well as a good fit. This screw has been developed to allow tightening to a high degree, which makes the screw ultra-secure.
They are perfect for all sorts of applications and products, both security and non security, and are used in a wide variety of industries including the electronics and robotics industries.
The Tri-Drive Micro Profile Head Screw features no cam-out, no driving force and high workability. These screws have high torque transmission, making them easier to screw in, and they have high durability. They require a special tool to fasten which renders them tamper resistant, preventing unauthorised people from interfering and removing them once fixed.
Please note – special tools are required to fit this screw, these are also available from Fastenright.
