Metric Class 8.8 Hex Head Screws – Medium Strength Industrial Fasteners

JIS Class 8.8 steel hex head screws are widely used in machinery, industrial equipment, and general engineering applications where reliable strength and durability are required.

Manufactured from high-quality carbon steel, these Grade 8.8 hex head screws provide excellent mechanical performance and dimensional accuracy. Zinc yellow-chromate plating or zinc plating provides improved corrosion resistance for applications exposed to moisture and industrial environments.

Key Features of Class 8.8 Hex Head Screws

• Manufactured according to JIS, ISO, and DIN standards

• High tensile strength and reliable mechanical performance

• Available with zinc plated and corrosion-resistant coatings

• Suitable for machinery assembly and industrial equipment

• Accurate thread engagement for secure fastening

• Available in metric sizes including M6, M8, M10, M12 and customized sizes

Common Applications

Class 8.8 hex screws are commonly used in:

• Industrial machinery

• Automation equipment

• Pumps and motors

• Mechanical structures

• Construction equipment

• General manufacturing applications

For engineers selecting industrial fasteners, metric Grade 8.8 hex head screws offer an excellent balance between strength, cost efficiency, and durability.

High-Strength Class 10.9 Hex Head Screws for Heavy-Duty Applications

For applications requiring higher mechanical strength, Class 10.9 high-strength hex head screws are designed for heavy-load fastening systems.

These 10.9 grade hex bolts provide superior tensile strength compared with standard medium-strength fasteners and are commonly selected for safety-critical assemblies.

Manufactured according to ISO and DIN specifications, JUXIN FASTENERS' high-strength hex screws are suitable for demanding industrial environments.

Advantages of Grade 10.9 Hex Head Screws

• Higher tensile strength for heavy-duty applications

• Excellent fatigue resistance under vibration loads

• Suitable for high-stress mechanical assemblies

• Available with zinc plating, zinc nickel plating, and corrosion-resistant coatings

• Traceable material certification available

• Manufactured with strict quality control

Typical Applications

High-strength Class 10.9 steel hex screws are widely used in:

• Automotive suspension systems

• Heavy machinery

• Hydraulic equipment

• Pumps and valves

• Motors and power equipment

• Structural connection systems

For automotive and industrial engineers requiring reliable fastening performance, 10.9 grade hex head bolts provide excellent strength and long-term reliability.

Dacromet Coated Screws – Advanced Corrosion Resistant Fasteners

Dacromet screws are high-performance coated fasteners designed for applications requiring enhanced corrosion protection.

The Dacromet coating process creates a thin protective layer on the screw surface, improving corrosion resistance, wear resistance, and service life.

Compared with standard zinc plated screws, Dacromet coated screws provide improved protection in harsh environments, especially where moisture, salt spray, and chemicals may affect conventional fasteners.

Benefits of Dacromet Screws

• Excellent corrosion resistance

• High durability and extended service life

• Good resistance to heat and harsh environments

• Improved surface protection against oxidation

• Suitable for outdoor and industrial applications

Industries Using Dacromet Fasteners

Dacromet screws are widely used in:

• Automotive manufacturing

• Transportation equipment

• Marine applications

• Oil and gas equipment

• Construction machinery

• Industrial machinery

For applications requiring strong corrosion protection and high mechanical performance, Dacromet coated high-strength screws are an ideal fastening solution.

Thread Selection Guide for Hex Head Screws

Choosing the correct thread type is important for safe and reliable fastening.

Coarse Thread Hex Screws

Coarse threads are the standard choice for most industrial applications.

Advantages:

• Faster installation

• Strong thread engagement

• Better performance in softer materials

• Widely used in machinery and general assembly

Fine Thread Hex Screws

Fine threads are designed for applications requiring higher vibration resistance and precise adjustment.

Advantages:

• Better resistance to loosening

• Higher tensile strength in some applications

• Suitable for automotive and precision equipment

JUXIN FASTENERS supplies both coarse thread and fine thread hex head screws according to customer drawings and engineering requirements.
