Black M8 M12 Carbon steel Extended hexagon nuts Class8. 8 Grade 8.8 Extended Metal hex nut

Hexagonal nuts are designed to work in conjunction with bolts and screws to provide secure fastening for machine parts. These Class 8.8 Grade 8.8 extended metal hex nuts offer superior strength and durability for demanding applications.

• Type I Nuts: Most widely used, available in A, B, and C grades for different precision requirements
• Type II Nuts: Thicker design for frequent assembly/disassembly applications
• Thin Nuts: Designed for applications with limited surface space

The hexagonal design provides excellent torque transmission and can withstand significant axial and radial loads. These nuts are manufactured to DIN standards from high-quality carbon steel.

• High strength Class 8.8 Grade 8.8 rating
• Available in various sizes including M8 and M12
• Extended design for improved grip and torque application
• Plain finish for general-purpose applications
• Customizable length and color options available

These versatile hex nuts are used across multiple industries:

• Construction: Steel structures, bridges, and building frameworks
• Mechanical Engineering: Automotive, marine, aviation, and machine tool applications
• Electronics: Secure fastening of electronic components
• Home Maintenance: Furniture assembly, bicycle repairs, and general household use

Carbon steel offers excellent strength and durability for demanding applications. The material can be classified by:

• Usage: Structural steel, tool steel, free-cutting steel
• Carbon Content: Low carbon (≤0.25%), medium carbon (0.25%-0.6%), high carbon (≥0.6%)
• Quality: Ordinary, high-quality, and premium grades

The 8.8 class designation indicates a tensile strength of 800 MPa and yield strength of 640 MPa (80% of tensile). When pairing with bolts, matching strength grades ensures optimal performance and safety.
