The security fastener range complements Killich wider product range of industrial fastenings and can be used alongside or instead of standard parts.  Specialist security fasteners allow specifiers to boost security and improve health and safety without compromising on fastener performance, or aesthetic.  In many ways security fasteners are favoured by specifiers as they offer an improved aesthetic from the traditional screw with a clean, smooth finish.

Security fasteners come in two main forms permanent (1-way), or removable (2-way) fasteners that cannot be removed, other than with matching tooling.  Each fastener has its own features and characteristics which dictate their security levels.  For ease we have classified our security ratings on a 1 to 5 scale (with 1 being entry level and 5 being the maximum security available).
