Product Feature

Jinghong Fasteners Cotter Pins also known as split pins or cotter keys, are simple and effective fasteners used to secure bolts, nuts, and other fasteners in a wide range of applications. Here are some key features and characteristics of cotter pins:

1. Design: Cotter pins typically have a simple and straightforward design. They consist of a metal pin with two tines that are bent during installation to secure the pin in place. The most common design is a straight pin with a loop at one end and two tines at the other end.

2. Materials: Cotter pins are commonly made from metal, with stainless steel and zinc-plated steel being popular choices. The material used is important for corrosion resistance and durability, especially in outdoor or corrosive environments.

3. Sizes: Cotter pins come in various sizes to accommodate different fastener dimensions. The size is usually determined by the diameter and length of the pin.

4. Ease of Installation: One of the key features of cotter pins is their ease of installation. They are inserted through the fastener (such as a bolt or nut) and then the tines are bent to secure the pin in place.

5. Secure Fastening: Cotter pins are effective in preventing nuts and bolts from unintentionally loosening due to vibrations or other forces. They provide a secure and reliable means of fastening.

6. Removability: Cotter pins are designed to be easily removable when it's necessary to disassemble components. This facilitates maintenance, repairs, and replacements.

7. Versatility: Cotter pins find applications in various industries, including automotive, construction, marine, and aviation. They are used in a wide range of equipment and machinery.

8. Cost-Effective:Cotter pins are relatively simple in design and cost-effective to manufacture, making them an economical choice for securing fasteners.

9. Safety: The use of cotter pins enhances safety by ensuring that fasteners remain securely in place, reducing the risk of accidents or equipment failure due to loose bolts or nuts.

10. Temperature Resistance: Depending on the material used, cotter pins can exhibit good temperature resistance, allowing them to maintain their integrity and functionality in a variety of operating conditions.

When using cotter pins, it's important to follow proper installation procedures to ensure they effectively secure fasteners and contribute to the overall safety and reliability of the equipment or structure.
