All nuts are bright zinc plated for increased corrosion resistance. Wide ranges of sizes to suit many applications. Security shear nuts are a high security, permanent nut fastening. Hexagonal part of the security shear nut shears off at a pre-determined torque, leaving a totally tamper proof cone. Can be used together with many fixing types, particularly Sleeve Anchors and Through Bolts. Ideal for security applications such as window grilles, roller shutters, external seating and playground equipment.
