Split Pin

Split pin often get surface coatings or treatments like galvanizing, zinc plating, or passivation to work better. Galvanized cotter pins are really good at fighting rust, which makes them great for outdoor use or on boats. Zinc-plated ones have a smooth surface, so they go in easier and don’t rub as much when you’re installing them. Stainless steel cotter pins might get passivated,this just means they strengthen the protective layer on them to resist rust even more. If they’re used in high-temperature places, they might get coatings like ceramic or polymer that can handle heat.

These treatments don’t just make cotter pins last longer; they can also make them look nicer. You can choose different finishes depending on what you need, so they work well in all kinds of situations.

Size

Split pin come in standard sizes,diameters from 1/16 inch up to 3/8 inch, and lengths from 0.5 inch to 6 inches,to fit different hole sizes and how deep they need to go in an assembly. They’re made in both metric and imperial measurements, so they work for markets around the world. The angle and how much the split ends spread are designed carefully to make sure they fit tight without stretching the metal too much.

If you need a special size for something specific, like tiny electronics or really heavy machinery, they can make custom ones. The packaging usually labels the dimensions clearly, which makes it easier to pick the right one. And they meet standards like ISO, ANSI, or military specs, so you know they’re consistent. Getting the right size is important,it helps them hold as much as possible and keeps them from breaking under pressure.

Features

Q: Are cotter pins reusable, or should they be replaced after removal?

A: Split pins are usually meant for one-time use because they get bent out of shape when you install them. If you straighten the bent ends after using them, the metal gets weaker, which could make them break under pressure. In important situations like machinery or car parts, always put in a new cotter pin after you take one out. But if you’re using them in places with less stress, check the reused pins for cracks or wear first. To be safe, it’s best to use a new one every time,they’re cheap, and it helps avoid any reliability issues.
