External-E E-Clip for Shaft Retention

The MIDWEST FASTENER CORP 36749 External-E E-Clip is a retaining ring designed to secure components onto a shaft groove. It is intended for industrial laypersons and military mechanics who need a reusable fastener that relies on spring deformation to stay in place. The clip provides an interference fit that must be elastically deformed during installation or removal.

Limits of Spring-Deformation Retention

This fastener depends on elastic deformation to maintain its grip within a groove or land. Repeated installation and removal cycles will gradually reduce the spring tension that creates the interference fit. The plain 18-8 stainless steel finish offers corrosion resistance but does not add a locking feature, so the clip can dislodge under high vibration or axial loads that exceed the spring force.

Replaces Worn or Lost Retaining Clips

This item replaces damaged, corroded or missing E-clips in existing assemblies where the groove dimensions match the clip specifications. The jump is worth it when the original fastener has lost enough spring tension to allow lateral play or when corrosion compromises the steel integrity. It is not suited for applications requiring a positive lock that prevents rotation or for grooves sized to other retaining ring standards.

Questions about this item

Which version of the 36749 E-Clip should I choose for my application?

The 36749 is a single type of external E-clip made from 18-8 stainless steel with a plain finish, designed to provide an interference fit onto a groove or land.

How does the 18-8 stainless steel construction perform once installed?

The 18-8 stainless steel offers corrosion resistance and relies on spring deformation to stay seated in the groove, requiring elastic deformation for installation or removal.

What groove standard does the 36749 E-Clip fit, and what does that limit?

It is sized for an interference fit on a standard groove or land, meaning the clip diameter and groove dimensions determine the maximum shaft size it can retain.
