El proceso de estampado en frío es uno de los nuevos procesos de mecanizado a presión de menor o ningún corte
metal. Es un método de transformación que utiliza la deformación plástica del metal bajo la acción de
fuerzas externas y, con ayuda de moldes, redistribuye y transfiere el volumen de metal para formar
las piezas o formatos necesarios. El proceso de estampación en frío es el más adecuado para producir piezas estándar.
elementos de fijación como pernos, tornillos, tuercas, remaches, pasadores, etc.
Hexagonal Pernos de cizallamiento – Description & Functionality
Hexagonal shear bolts are specialized fasteners designed for tamper-resistant and security-critical applications. They feature a unique breakaway design that prevents unauthorized removal once installed.
Características principales
-
Hexagonal Head Design
-
Standard 6-sided head for easy installation using a wrench or socket.
-
Made to shear off at a predetermined torque, leaving no gripping surface.
- Hexagon shear bolt
-
-
Shear Mechanism
-
The head is engineered to romper once the bolt reaches its specified tightening torque.
-
After shearing, only a smooth, cylindrical shank remains, making removal difficult without specialized tools.
-
-
Threaded Shank & Tail
-
En protruding tail (excess length) may be cut flush for safety and aesthetics.
-
-
Material & Hardness
-
Normalmente se fabrica con hardened steel (grade 8.8, 10.9, or stainless steel).
-
Resists drilling, cutting, and tampering.
-
-
Security Benefits
-
Tamper-proof: No exposed head after installation.
-
Vandal-resistant: Difficult to remove without destructive methods.
-
Controlled installation: Ensures proper clamping force.
-
How Hexagonal Shear Bolts Work
-
Installation
-
Inserted into a pre-drilled hole and tightened with a wrench.
-
At the precise torque, the hexagonal head snaps off.
-
-
Removal (If Required)
-
Requires special extraction tools (e.g., left-hand drill bits, bolt extractors).
-
Often necessitates drilling or grinding.

-
Aplicaciones comunes
-
Traffic & infrastructure: Street signs, traffic lights, railway tracks.
-
Public utilities: Electrical enclosures, meter boxes.
-
Security systems: Bollards, fencing, access panels.
-
Heavy machinery & automotive: Critical assemblies requiring tamper resistance.
