DIN906 Carbon Steel Hexagon Socket Pipe Plug

Product Specification

DIN906 Carbon Steel Hexagon Socket Pipe Plug

Product Description

Standard:DIN906

DIN 906 is a well-recognized German industrial standard for hexagon socket pipe plugs (also named oil plugs/threaded blanking plugs), which are core sealing and blanking fasteners widely applied in industrial fluid systems. Its design and performance are strictly standardized, with the following prominent characteristics, all described in professional industrial English for foreign trade promotion, product specifications and technical

Core Features:

1. Standardized Structural Design

Adopt a one-piece integral structure with a recessed hexagon socket drive at the top, featuring compact and streamlined dimensions that fit perfectly in confined installation spaces (e.g., hydraulic cylinders, gearboxes) where regular fasteners are hard to operate.The external thread section is fully matched with the standard, and the plug body has a reasonable thickness design to ensure structural rigidity and avoid deformation under pressure.

2. Versatile Thread Configurations

Cover a full range of industry-standard pipe threads to adapt to different pipeline sealing requirements worldwide, including metric fine threads (M series), British parallel pipe threads (G), British taper sealing pipe threads (R) and American national pipe taper threads (NPT).All threads are manufactured in strict accordance with DIN tolerance standards, with high thread precision, stable meshing and good interchangeability with matching pipe joints.

3. Reliable Sealing & Pressure Resistance

The precision-machined thread surface forms a mechanical sealing fit with pipeline internal threads; the plug can be used with thread sealant or Teflon tape for enhanced leak-proof performance, effectively preventing the leakage of oil, water, hydraulic oil and other media.It has excellent pressure-bearing capacity, and the finished product can withstand high working pressure of industrial fluid systems (hydraulic/pneumatic) without seal failure, suitable for medium and high pressure working conditions.

4. Diversified Material & Corrosion Resistance Options

The base materials are selectable according to application scenarios: carbon steel (45# steel, 8.8/12.9 property class) for general industrial low-corrosion environments; 304/316 stainless steel for corrosive media or outdoor/chemical working conditions; brass for hydraulic/pneumatic systems with high anti-rust requirements.Various professional surface treatments are available, such as zinc plating, yellow zinc passivation, black oxide coating, dacromet coating and nickel plating, which further improve the anti-rust and corrosion resistance of the product and extend its service life in harsh environments.

5. Precision Machining & Stable Performance

The production adopts advanced processes such as cold forging, precision turning and thread rolling, with no burrs on the product surface and uniform thread tooth shape, avoiding thread jamming during installation and disassembly.Key workpieces undergo heat treatment (quenching and tempering) to optimize mechanical properties such as tensile strength and hardness, ensuring the plug is not easy to break or slip during tightening and disassembly.

6. Easy Installation & Operation

The hexagon socket drive design matches standard hexagon socket wrenches, enabling quick and convenient installation and disassembly with no need for special tools; the torque force is evenly transmitted during operation, reducing the risk of thread damage caused by uneven force.The standardized product size ensures perfect compatibility with mainstream industrial pipeline equipment, with strong interchangeability, suitable for batch assembly in industrial production lines.

7. Wide Industrial Adaptability

The product is designed for industrial fluid system sealing, and is widely used in hydraulic systems, pneumatic components, construction machinery, automobile engines, gearboxes, hydraulic cylinders, oil tanks, water pumps and other equipment, as well as chemical, shipbuilding and metallurgical machinery pipeline systems.

Packaging

Carton Packaging	Outer Cartonbox Packaging	Pallet Packaging
Bolts are packed in neutral packaging boxes, with standard quantities arranged in small cartons. The exact number of units per carton will be confirmed with the customer to align with their specific requirements. Customized packaging configurations are available upon request.	The small cartons are then consolidated into larger master cartons for secure transportation and storage. The quantity per master carton can be customized based on client specifications or aligned with standard logistical requirements.	The palletized units are securely wrapped with waterproof film and reinforced with packaging straps. Customer-specific shipping marks or labels are affixed to each pallet, ensuring clear identification and compliance with logistics requirements. This final packaging stage guarantees weather-resistant protection and stability during transportation.
