Stainless steel hexagon oil plug screw

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.

Stainless Steel Hexagon Oil Plug Screw – Detailed Description

A stainless steel hexagon oil plug screw is a precision-engineered fastener designed to securely seal oil drain ports in engines, gearboxes, hydraulic systems, and industrial machinery. Its corrosion-resistant construction and hexagonal head design ensure durability, easy installation, and leak-proof performance.

Key Features & Specifications

1. Material & Finish

• Stainless Steel Grade: Typically A2 (304) or A4 (316) for superior corrosion resistance against oil, water, and chemicals.

• Surface Finish: Polished, brushed, or natural mill finish to prevent galling and ensure smooth threading.

2. Head Design

• Hexagonal (Hex) Head: Allows tightening/loosening with a wrench, socket, or Allen key (depending on design).

  • Common sizes: 10mm, 12mm, 14mm, 17mm (automotive), or custom industrial sizes.

• Flanged Variants: Some models include an integrated washer flange for better sealing without a separate crush washer.

3. Thread Type & Size

• Metric Threads (e.g., M12x1.5, M14x1.5, M18x1.5) – Common in automotive and machinery.

• NPT (National Pipe Taper) Threads – Used in hydraulic and industrial systems for a pressure-tight seal.

• BSP (British Standard Pipe) Threads – Found in European and Asian machinery.

4. Sealing Mechanism

• Crush Washer (Copper/Aluminum): Ensures a leak-proof seal when torqued.

• Integrated O-Ring/Gasket: Some models feature a built-in rubber or silicone seal.

• Magnetic Tip (Optional): Captures metal debris for engine protection.

5. Applications

• Automotive: Engine oil pans, transmissions, differentials.

• Industrial: Hydraulic systems, gearboxes, compressors.

• Marine: Boat engines and machinery exposed to saltwater.

Variations & Special Types

• Magnetic Oil Plug: Contains a magnet to trap metal particles.

• Quick-Drain Valve Plug: Allows oil changes without full removal.

• Extended Thread Plug: For thicker oil pans or custom applications.

Standards & Compatibility

• DIN 908 / DIN 910 (German industrial standards).

• ISO 4032 (Metric hex bolts).

Why Choose a Stainless Steel Hex Oil Plug?

• Reliability: Ensures a tight seal under vibration and thermal expansion.

• Compatibility: Works with synthetic and mineral oils.

• Maintenance-Friendly: Easy to remove even after prolonged use.

Ideal for automotive workshops, industrial maintenance, and marine applications where corrosion resistance is critical.
