Das Kaltstauchverfahren ist eines der neuen Verfahren für die Druckbearbeitung mit weniger oder gar keiner Zerspanung
Metall. Es handelt sich um eine Verarbeitungsmethode, die die plastische Verformung von Metall unter der Einwirkung von
äußere Kräfte, und mit Hilfe von Formen wird das Metallvolumen umverteilt und in die Form gebracht
die gewünschten Teile oder Rohlinge. Das Kaltstauchverfahren ist am besten geeignet für die Herstellung von Standard
Verbindungselemente wie Bolzen, Schrauben, Muttern, Nieten, Stifte usw.
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
-
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.
-
-
Drive Types:
-
Slotted (flat-head screwdriver).
-
Phillips (cross-head screwdriver).
-
Hex socket (Allen) (less common but used for higher torque).
-
-
Thread Type:
-
Metric (M6, M8, etc.) oder imperial (UNC/UNF) threads.
-
May include tapered threads (NPT) oder straight threads with sealing features.
-
-
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).
-
-
Materials & Coatings:
-
Stahl (carbon or alloy), rostfreier Stahl (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).
