Fastening against theft and vandalism

The need to safeguard against theft, vandalism and tampering is an increasingly essential part of many design specifications.

Hafren security fasteners from Challenge Europe can be used in a range of security applications in projects and manufacturing all over the world. For example, in engineering equipment to prevent tampering while leaving access available to qualified personnel with specialist tools, such as 2-hole (often referred to as ‘snake eye’ or ‘pig nose’) head designs or pin hex screw heads and barrel nuts.

Typical applications include architecture, parks and playgrounds, automotive, instrumentation, airports and rail stations, prisons, signage, fencing, regeneration projects, public venues, on the street.

Most designs are removable in some way by use of specialist tools – other designs, e.g. shear nuts and shear bolts, are not intended for removal other than by destruction, perhaps by grinding, drilling or brute force.
