Grade 8.8 M8 M10 M12 5 Blue Zinc Plated Carbon Steel Hex Head Flange Metal Bolt DIN6921

Grade 8.8 M8 M10 M12 5 Blue Zinc Plated Carbon Steel Hex Head Flange Metal Bolt DIN6921

Product Description:

Types of Galvanization
Galvanized hex bolts are coated with zinc through two primary methods:

Hot-Dip Galvanizing (HDG):

The bolt is immersed in molten zinc (≈450°C), forming a thick, robust zinc-iron alloy layer.

Provides superior corrosion resistance (up to 50+ years in mild environments).

Ideal for outdoor or marine applications.

Thicker coating (50–150 μm) but may have a slightly rough surface.

Electro-Galvanizing (Electroplating):

Zinc is deposited via electrolysis, creating a thin, smooth coating (5–25 μm).

Offers moderate corrosion protection, suitable for indoor or dry environments.

Maintains precise thread dimensions due to thinner coating.

2. Key Applications
Galvanized hex bolts are essential in industries exposed to moisture, chemicals, or weather:

Construction & Infrastructure:

Structural steel connections (beams, bridges, towers).

Roofing, HVAC systems, and outdoor fixtures.

Automotive & Transportation:

Chassis components, trailers, and marine equipment.

Energy & Utilities:

Power line towers, wind turbines, and solar panel mounts.

Technical Parameters:

Applications
Hex flange bolts are widely used in industries requiring reliable, vibration-resistant fastening:

Automotive: Engine components, transmission systems, and chassis assemblies.

Machinery: Heavy equipment, pumps, and hydraulic systems.

Construction: Structural frameworks, HVAC systems, and metal roofing.Electronics: Securing components in appliances or industrial devices.

Aerospace: Non-critical assemblies where weight and vibration resistance are prioritized.

Vibration Resistance: Preventing loosening under dynamic loads or vibrations.

Alignment: Ensuring precise positioning of connected parts due to their integrated flange.

Key Features

Integrated Flange: A built-in circular flange beneath the hexagonal head eliminates the need for separate washers, distributing load evenly and reducing surface damage.

Hexagonal Head: Allows easy tightening/loosening with standard wrenches or sockets.

Serrated Flange (Optional): Some variants feature serrations on the flange underside to enhance grip and anti-rotation properties.

Material Versatility: Available in steel, stainless steel, or coated alloys for corrosion resistance.

Durability: Engineered to withstand high stress, temperature variations, and harsh environments.
