Breakaway Anti-Theft Nut

Product Parameter

Dual-Body Torque Shearing Structural Principle

The core advantage of Breakaway Anti-Theft Nuts lies in the professionally designed dual-body separation structure and precision shear groove technology, which is fundamentally different from all reusable standard nuts. The product is composed of an outer hexagonal torque application layer and an inner permanent locking base, with a precision stress concentration shear groove preset at the joint. During installation, the outer hexagon bears the twisting force of the tool to complete pre-tightening. Once reaching the factory-calibrated standard torque value, the shear groove will undergo precise and uniform fracture separation, automatically removing the outer auxiliary stress part. The remaining smooth cylindrical thread base has no flat stress surface for conventional wrenches, pliers and other tools, thoroughly eliminating the possibility of man-made disassembly, theft and malicious loosening. This structural design integrates precise locking, torque control and permanent anti-theft functions in one, solving the long-standing pain points of poor anti-theft effect and easy artificial dismantling of ordinary fasteners in public facility protection scenarios.

Customized Stainless Steel Material Torque Stability

All Breakaway Anti-Theft Nuts adopt specially tuned 304 and 316 stainless steel raw materials, which balance structural toughness and precise shear performance, completely adapting to the product’s one-time torque breaking working principle. Different from ordinary fastener materials that only pursue hardness, the selected stainless steel materials undergo special tempering treatment, with stable internal stress and uniform mechanical properties, ensuring that each nut can complete shear separation at the preset standard torque without premature fracture or failure to break. The material retains excellent outdoor corrosion resistance, salt spray resistance and oxidation resistance, avoiding structural rust, scale and performance attenuation caused by long-term exposure to outdoor, humid and coastal environments. Each batch of raw materials is tested for tensile strength and shear resistance to ensure consistent torque accuracy and structural stability of finished products in batch production.

Precision Torque Calibration Production Technology

The production of Breakaway Anti-Theft Nuts focuses on ultra-precise control of shear torque, adopting integrated one-piece forming and multi-process precision calibration technology. The whole process includes high-precision bar blanking, integral turning forming, precise shear groove positioning milling, standard thread rolling, stress relief treatment, torque sampling calibration and finished product screening. The core shear groove is processed by fixed-depth precision milling, with strictly controlled groove width and depth tolerance, ensuring consistent shear threshold of each product. After processing, all products undergo low-temperature stress relief to eliminate processing residual stress and prevent torque deviation caused by structural stress. Batch random torque destructive testing is carried out to verify the stability of shear performance, ensuring that every finished nut can achieve accurate breaking and reliable locking in actual engineering installation.

One-Time Locking & Scenario-Based Assembly Guidelines

Breakaway Anti-Theft Nuts are professional one-time safety anti-theft fasteners, applicable exclusively to permanent fixed installation scenarios without subsequent disassembly and maintenance. Before assembly, clean the bolt thread and fitting surface to avoid foreign matter affecting pre-tightening accuracy and shear effect. Use standard matching tools for uniform and steady tightening; do not use extension rods or impact tools to avoid excessive instantaneous torque leading to premature shear failure. The nut will automatically break the outer hexagonal body after reaching the rated locking torque, forming a flat and safe locking terminal surface. It is strictly prohibited to repeatedly tighten or disassemble the product after shearing, as the structural performance will be completely locked and cannot be restored. This product is not suitable for equipment that requires regular overhaul and disassembly, and is only targeted at public facilities, municipal projects and safety protection structures that require permanent anti-theft and anti-loosening.
