The Essential Guide to Circlips: Types, Sizes & Professional Applications

Discover precision-engineered circlips at HomeDIYer – your solution for securing bearings, axles, and piston pins. From stainless steel E-clips to heavy-duty external rings, our collection includes specialized removal tools and pliers for effortless installation. Trusted by mechanics and engineers for industrial-grade retention.

1. Why Circlips Matter in Mechanical Systems
Circlips (or retaining rings) secure components like piston pins, axle joints, and bearing assemblies. A failed circlip ring can cause catastrophic damage – which is why professionals choose HomeDIYer's stainless circlip kits. Our titanium C-clips offer 3x higher shear strength than standard models, ideal for Mercury ball vape systems or high-torque applications.

2. Types of Circlip Pliers: When to Use Each

Internal Circlip Pliers: For grooves inside housings (e.g., master cylinder circlip)
External Circlip Pliers: Grip outer rings (e.g., shaft circlip or CV axle circlip)
90-Degree Bent Pliers: Access confined areas like piston circlip grooves
Adjustable Pliers: Handle multiple sizes (e.g., 3mm-50mm circlip)

Pro Tip: For clevis pin circlips, use Knipex-style pliers with reversible jaws. Avoid cheap tools – they deform rings during circlip removal.

3. Step-by-Step: Removing Stubborn Circlips

"How to remove a circlip without damaging components?" Follow these steps:

Select pliers: Internal for bore grooves, External for shafts.
Position tips: Align with circlip ring holes at 90°.
Apply steady pressure: Use circlip removal tool for rusted rings.
Inspect: Replace deformed rings with our stainless circlip kits.

Wrong tool sent

Better than expected!

I was surprised these performed so well on my granite counter top considering the price! I thought I would go through all 5 bits but I successfully drilled through using only one bit. And it was sharp from start to finish!

I used plenty of water to lubricate, and took a few breaks to let the bit cool down.

It’s Only

The bit is having a hard time punching the hole
in my stainless steel kitchen sink. Gets real hot, real quick. I have to stop and let It cool. Taking forever.

They do what they're supposed to do.

The quality on these post screws seems to be really well. The size is perfect for small projects like leather and kydex. They look great. They seem to hold up very well. I have no issues with their performance. I've ordered several packs and I will continue to order.

Very light, easy to use, has metric and imperial

Very surprised by how simple and effective this is.
Easy to separate halves that you squeeze around the bolt.
Has a keychain, not really something I want to carry around.
Tested for various bolts and it works fine. Like it - I recommend it.
