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.
Double Hole Safety Wire Bolt – Comprehensive Overview
A Double Hole Safety Wire Bolt is a specialized fastener designed to remain securely locked in place even under extreme vibration, rotation, or dynamic loads. Unlike standard bolts, it incorporates two precisely drilled holes—typically in the head or along the shank—to accommodate a safety wire (lock wire) that physically prevents loosening.
Design & Construction
-
Hole Configuration:
-
Radial Holes (Most Common): Two small holes drilled perpendicular to the bolt’s axis, allowing the wire to pass through the sides of the head.
-
Axial Holes (Less Common): Holes drilled along the bolt’s length, used in specific applications where radial wiring isn’t feasible.
-
How It Works
-
If the bolt tries to rotate, the wire resists movement.
-
Proper wire tension ensures no slack, maintaining constant resistance.
Wiring Methods:
-
Multi-Bolt Group Locking: A continuous wire threads through multiple bolts in series, securing an entire assembly.

Key Applications
-
Aerospace: Jet engines, landing gear, and flight control systems (FAA/SAE standards).
-
Military/Defense: Firearms, armored vehicles, and aircraft (MIL-SPEC compliance).
-
Marine & Industrial: Pumps, turbines, and machinery exposed to constant motion.
Installation Best Practices
-
Wire Selection: Use stainless steel or Monel wire (0.020″–0.041″ thickness).
-
Tension: Maintain 6–8 twists per inch; too loose = ineffective, too tight = may break.
-
Inspection: Regular checks for wire integrity (no fraying or corrosion).
Conclusion
Double hole safety wire bolts provide the most reliable mechanical locking in extreme conditions where failure is not an option. Their design ensures longevity, reusability, and fail-safe operation, making them indispensable in aerospace, motorsports, and heavy industry.
