Surface Treatment Options

Black Finish

The black surface option provides a dark appearance and is suitable for machinery, equipment and fastening assemblies where a black component is preferred. It can be used in industrial structures, equipment frames and mechanical assemblies.

Zinc Finish

The zinc surface option provides a bright metallic appearance and is suitable for general industrial fastening. It can be used for equipment installation, threaded connections and steel structure assembly where an additional protective surface is required. The final surface treatment should be selected according to the thread size, grade, application environment and required appearance.

Application

This double ended stud bolt can be used in the following applications:

• Industrial machinery assembly
• Equipment frame installation
• Steel structure connections
• Mechanical component fastening
• Flange and bracket assembly
• Heavy equipment installation
• Threaded sleeve connections
• Maintenance and repair work
• Industrial support structures
• General-purpose metric fastening systems

The double ended design is useful when both sides of the connection require threaded engagement. The stud can be installed through a component, bracket or support plate and secured with matching nuts and washers. For larger sizes such as M27, M64 and M76, buyers should select the nut, washer and installation tools according to the actual assembly design and load requirements.

Matching Fasteners

Flat washers can be used to distribute the clamping force over a wider surface area. Spring washers may be used in assemblies where additional resistance to loosening is required. Threaded sleeves or coupling nuts can be used when a longer threaded connection or extension is needed.

All matching components should use the same nominal thread size and a compatible strength level. For heavy-duty installations, the complete fastening system should be selected according to the engineering requirements of the equipment or structure.
