System Zero Security Screws
System Zero security screws utilise an external non-slip drive head with indentations which the matching security tool grips in order to fasten and remove.
They are suitable for high torque applications and the facility to remove the screws makes them suitable for use where a moderate level of security is required, with the ability to regularly maintain whatever is being protected.
Machine screws and self-tapping screws are available in stainless steel and zinc plated steel, manufactured to order only.
For urgent requirements, E-5 and E-6 security screws are an alternative option, offering similar features and levels of security and often available from stock, please enquire. The E-5 is quite unique as it is available in smaller sizes than most other security screws. See more info here.
Special E-5 Drive Security Screws can be made to order including small volume manufacture, modifications and custom parts to drawings.
