Material and application
Made from stainless steel A2. The nuts are intended for permanent security joints, including fencing, signs and boards, and street furniture. Breaking off the hexagon limits access to the spanner flats; it does not make removal by specialist methods completely impossible.

Scope of supply and installation
The price includes 100 M8 A2 nuts. The carton graphic is a neutral illustration; the number of visible items does not determine the quantity supplied or the factory packaging method.

After it breaks off, the component is intended to remain in the joint, rather than be reused. The stated dimensions must not be treated as instructions for selecting a tightening torque.
