They provide a high security, permanent fastening, as the hexagonal part of the nut shears off at a pre-determined torque, leaving a totally tamper-proof cone.
Ideal for security applications such as window grilles, roller shutters, external seating and playground equipment.
Can be used together with many fixing types, particularly Sleeve Anchors and Through Bolts.
Zinc coatings prevent corrosion of the protected metal by forming a physical barrier, and by acting as a sacrificial anode even if this barrier is damaged.
