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.
Flange Hexagonal Groove Oil Plug – Overview
A flange hexagonal groove oil plug is a specialized sealing fastener designed for fluid retention in engines, gearboxes, hydraulic systems, and industrial machinery. It combines a hex head for tool engagement, a flange base for secure sealing, and often a groove for an integrated O-ring or gasket.Flange Hexagonal Slot Oil Plug Screw
Key Features & Design Elements
1. Head Design
-
Hexagonal (6-sided) head – Allows tightening/loosening with a standard wrench, socket, or Allen key (depending on design).
-
Flange base – A widened, flat collar that distributes clamping force, prevents over-tightening, and improves sealing.
-
Groove for O-ring/gasket – A machined recess near the threads houses a rubber or silicone O-ring for a leak-proof seal.
2. Thread Type
-
Straight threads (BSPP, UNF, Metric) – Often used with sealing washers or O-rings.
-
Tapered threads (NPT, BSPT) – Self-sealing when torqued properly.
-
Common sizes: M12x1.5, M14x1.5, 1/2″ NPT, 3/4″ BSPP (varies by application).
3. Sealing Mechanism
-
Integrated O-ring (most common) – Provides a reusable, pressure-resistant seal.
-
Copper/aluminum crush washer – Used in high-torque applications (single-use).
-
Metal-to-metal sealing (in flanged designs without a groove).
