Pan head oil plug screw

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.

Pan Head Oil Plug Screw – Overview

A pan head oil plug screw is a threaded fastener designed to seal oil ports, drain holes, or fluid reservoirs in mechanical systems. It features a domed (pan-shaped) head with an external drive (typically slotted, Phillips, or hex) and a threaded body for secure installation.

Key Features & Characteristics

1. Head Design:

   • Pan head (low-profile, rounded top with flat bearing surface).

   • Provides a slight protrusion for easy tool access while maintaining a smooth contour.

2. Drive Types:

   • Slotted (flat-head screwdriver).

   • Phillips (cross-head screwdriver).

   • Hex socket (Allen) (less common but used for higher torque).

3. Thread Type:

   • Metric (M6, M8, etc.) o imperial (UNC/UNF) threads.

   • May include tapered threads (NPT) o straight threads with sealing features.

4. Sealing Mechanism:

   • Often paired with an integrated washer, O-ring, or copper gasket to prevent oil leaks.

   • Some designs rely on thread sealant (e.g., Teflon tape).

5. Materials & Coatings:

   • Acero (carbon or alloy), acero inoxidable (corrosion-resistant), or brass (for non-sparking applications).

   • Coatings: Zinc-plated, black oxide, or PTFE-coated for durability.

   • Pan head oil plug screw.

Common Applications

• Sealing engine oil pans, gearboxes, hydraulic systems, and differential housings.

• Acting as drain/fill plugs in automotive and industrial equipment.

• Used where a low-profile head is preferred over hex bolts or flanged plugs.

Variants

• Slotted pan head plug (basic, tool-simple).

• Phillips pan head oil plug (common in consumer machinery).

• O-ring pan head screw plug (integrated seal for better leak prevention).
