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.
Description of a Square Oil Plug Screw
A square oil plug screw is a threaded fastener designed to seal oil or fluid ports in mechanical systems, such as engines, gearboxes, and hydraulic units. Its defining feature is a square-shaped head, which allows for easy installation and removal using a standard wrench or square-drive tool.
Key Features & Design Elements
1. Head Design
-
Square head (typically 4-sided) for wrench engagement.
-
Some versions have a flanged base to improve sealing and distribute pressure.
-
Low-profile design to prevent snagging in tight spaces.
2. Thread Type
-
Tapered threads (NPT – National Pipe Taper): Creates a tight seal when screwed in, commonly used in fluid systems.
-
Straight threads (NPS/BSPP): Requires a sealing washer or O-ring to prevent leaks.
-
Metric or SAE (Imperial) thread standards, depending on application.
3. Sealing Mechanism
-
Integrated O-ring or rubber gasket (for reusable, leak-proof sealing).
-
Copper or aluminum crush washer (single-use, deforms to create a seal).
-
Tapered threads (self-sealing in NPT plugs).
-
Some plugs have magnetic tips to capture metal debris in oil systems.
Primary Applications
-
Engine oil drain plugs (cars, motorcycles, heavy machinery).
-
Transmission & differential fill/drain plugs.
-
Hydraulic system access points.
-
Gearboxes, pumps, and industrial equipment.
