Product Selection Differences for Metric Split Pins

Metric split pins, also known as cotter pins, are mechanical fasteners commonly used to secure bolts and other assemblies in place. When selecting metric split pins, some key differences to consider include:

1. Material: Metric split pins are typically made from materials such as carbon steel, stainless steel, or brass. The material choice should be based on the specific application requirements, including factors like corrosion resistance, strength, and temperature resistance.

2. Size and Length: Metric split pins come in various sizes and lengths to accommodate different bolt diameters and thicknesses. It is important to select the right size and length to ensure a proper and secure fit.

3. Standard vs. Heavy Duty: Depending on the application and the load-bearing requirements, you may need to choose between standard duty or heavy-duty metric split pins. Heavy-duty split pins are thicker and stronger, providing greater stability and support.

4. Head Type: Metric split pins are available with different head types, such as extended prong, extended head, and double loop. The head type can affect the ease of installation and the security of the fastening.

5. Finish: Metric split pins may come with different finishes, such as plain, zinc-plated, or galvanized. The finish can impact the corrosion resistance and overall appearance of the split pin.

6. Certification: Some industries may require metric split pins to meet specific standards or certifications, such as ISO, DIN, or ASTM. Ensure that the split pins you choose comply with the necessary standards for your application.

By carefully considering these factors, you can select the most suitable metric split pins for your specific needs, ensuring proper fastening and reliability in your assemblies.
