TWIST” BREAK OFF FASTENERS

“TWIST” Security Fasteners are permanent security fasteners that cannot be removed once fixed, thus protecting your products from vandalism, theft, and tampering from unauthorised individuals. These premium security fasteners are designed with a unique shear off feature that causes the hexagonal part of the fasteners to break off upon surpassing the maximum torque limit, leaving behind a tamper proof fastening. The special design of “TWIST” fasteners does not require any special tools and it can be installed using standard spanners and sockets. The one-way action makes these fasteners ideal for applications where maintenance is not required. “TWIST” Security Fasteners are available in the form of bolts, nuts and as a combination. A “TWIST” fastener today can ensure the safety of your product for a lifetime.

“TWIST” BREAK OFF NUTS       Item Code B4K22

Security screws, bolts, and nuts are designed so that ordinary tools cannot remove them. Removal can only be accomplished with special tools. Suitable for high torque applications, these nuts are manufactured for precision under the guidance of professionals. Upon tightening the nut, once the specified torque is exceeded, the hex portion shears off leaving behind a cone head which has no grip and therefore tamper-proof. A fit and forget solution that has proved its reliability over the years.
These nuts are very versatile and find wide usage in fencing, defence equipment, Solar and Energy installations and aerospace industry.
