Retainer Clips 101: Everything You Need to Know About the Different Types

Retainer clips are used in various applications to secure and hold objects in place. They come in different shapes, sizes, and materials depending on their specific function. Here are some common types of retainer clips:

1. Spring Clips

Spring clips, also known as spring fasteners or snap clips, are designed with a spring mechanism that allows them to securely hold objects in place. They typically have a curved or U-shaped design and provide a quick and convenient method for securing and releasing components.

2. Push-in Retainer Clips

Push-in retainer clips, also called push-type retainers or panel clips, are commonly used in automotive applications to secure panels, trim, and other components. They have a push-in design where the clip is inserted into a pre-drilled hole and expands or locks in place to secure the object.

3. Ratchet Clips

Ratchet clips, also known as ratchet fasteners or adjustable clips, have a unique mechanism that allows for adjustable tension. They typically consist of two interlocking components that can be adjusted and locked into position to hold objects firmly.

4. Circlip Retainer Clips

Circlip retainer clips, also called snap rings or retaining rings, are used to secure components onto shafts or inside bores. They have a circular shape and are installed in a groove on the shaft or inside a bore. Circlip retainer clips come in internal and external types, depending on their installation location.

5. E-Clips

E-clips, also known as E-style retaining rings or external retaining rings, have an “E” shape and are used to secure components onto shafts. They are installed into a groove on the shaft and provide a secure and easy-to-remove method of retention.

6. Hairpin Cotter Pins

Hairpin cotter pins, also called hitch pins or R-clips, have a hairpin-like shape and are used to secure objects such as hitch assemblies or clevis pins. They have a looped end that can be inserted into a pre-drilled hole and a curved leg that prevents the pin from slipping out.

These are just a few examples of retainer clips, and there are many other variations and designs available depending on the specific application and industry. The choice of retainer clip will depend on factors such as the desired level of security, ease of installation and removal, and compatibility with the objects being retained.
