Hey DIYers and mechanics! This Epi-Torque snap ring kit is exactly what you need when you're working on projects that require those pesky internal retaining rings. You get 75 pieces total across 12 different sizes - from 18mm all the way up to 38mm. They're made from hardened carbon spring steel with that phosphate and oil finish that helps prevent rust. The breakdown is super handy: you get 10 pieces each of the 18mm, 19mm, and 20mm sizes (since those are the most commonly used), then 5 pieces each of 22mm, 24mm, 25mm, 26mm, 27mm, 28mm, 33mm, 35mm, and 38mm. They come in this really practical storage box with 24 removable compartments so you can organize them exactly how you want. These circlips (some people call them C-clips, Seeger rings, or even Jesus clips) are semi-flexible so you can snap them into machined grooves on dowel pins or shafts - they allow rotation but stop lateral movement. Perfect for automotive work, machinery, bearings, valves, or any project where you need to secure components in place. Installation is easy with needle-nose pliers or a flat-head screwdriver for leverage. Having this assortment means you'll almost always have the right size on hand instead of running to the hardware store mid-project. The quality is solid - spring steel grade 70C6 or 75C6 that can handle the pressure without deforming. Seriously, if you work on cars, machinery, or any mechanical projects, this kit will save you so much time and frustration.
