DIN 6912 Hexagon Socket Cap Head Machine Thread Bolt

Key Features & Advantages:

1.Hex Socket Drive Design

Featuring a standard hex socket (cup head) drive, compatible with Allen keys or power bits, these bolts offer high torque transmission efficiency, reduced slipping, and can withstand high torque for high-load, high-stress applications.

2.High-Strength Carbon/Alloy Steel Material

Made of premium carbon/alloy steel (Grade 8.8/10.9/12.9) with quenched and tempered heat treatment, they offer high hardness, toughness, and tensile strength far exceeding ordinary carbon steel. They have excellent wear and fatigue resistance, resisting breakage and deformation.

3.Compact Cylinder Head Structure

The standard cylinder head has a small diameter, enabling flush or countersunk installation without occupying extra space, ideal for compact assembly scenarios inside equipment or in narrow gaps.

4.Full Machine Thread Structure

The shank features standard full machine threads with uniform pitch for smooth engagement, compatible with standard nuts or tapped holes, offering strong versatility for use with most conventional fasteners.

5.Multiple Surface Treatments

Available with blue-white zinc, colored zinc, black oxide, Dacromet, and stainless steel finishes for excellent corrosion, wear, and weather resistance, suitable for indoor, outdoor, and mildly corrosive environments.

6.High-Precision Thread Machining

Precision thread rolling ensures tight tolerance control, preventing jamming or workpiece damage during installation, suitable for automated equipment and precision machinery assembly.

7.Wide Range of Sizes

Available in diameters from M4 to M36 and various lengths to fit different mounting holes, load requirements, and working conditions, covering most industrial connection needs.

Common Applications:

• Precision Machinery Manufacturing: Structural connection and fixing of automated equipment, CNC machine tools, and precision instruments, suitable for compact assembly scenarios.
• Molds & Tooling Fixtures: Assembly and fixing of molds, fixtures, and jigs in high-torque, high-load applications.
• Industrial Automation Equipment: Component fixing and connection for conveyor lines, robots, and automated production lines.
• Automotive & Rail Transportation: Connection and fixing of automotive engine parts, chassis accessories, and rail transportation equipment.
• Electronic Equipment Manufacturing: Internal assembly and fixing of chassis cabinets, communication devices, and large equipment.
• Aerospace & Defense: Fasteners for precision instruments and defense equipment in high-strength, high-precision scenarios.
• Repair & Renovation Projects: Connection and reinforcement in equipment maintenance and tooling modification, replacing worn bolts to restore equipment performance.
