200 Piece Muzerdo Spring Assortment Set | Zinc Plated Compression and Extension Springs

As noted in other reviews, these are small, lightweight springs. Luckily that's exactly what I needed for some prototyping and crafting projects. Wasn't sure exactly what would work, so this variety pack is perfect for testing. Would probably work great for modeling kits and replacing toy parts, too.Since the springs are all jumbled together in the product photos it was a little hard to tell exactly what this variety pack contained, so here are some pictures in more organized arrangements to give you a better idea.Biggest downside is that the item tallies seem to be approximations rather than exact. Very few of the pieces had the correct amounts - some were over but most were under. I ended up 8 springs shy of the advertised total.

Bought these to use in a 3D printed one-way clutch. Comes with a wide variety of sizes, all of them are relatively light and do not take much force to compress. Worked great for my application, would use again elsewhere if corrosion was not a concern and low compression force was necessary.

This pack is great. I'd give it 5 stars if it had the working range and spring force for them.

Great value for DIY, better price than big box outlet. Only complaint is spring needs another loop on end (double loop).

Needed a spring for my airsoft rifles charging handle and it works great. I like that there were different sizes I could choose from.

Great assortment of springs for all types of repairs or projects.

These springs are very light weight. It is not what I was expecting in terms of spring strength. But then I guess it is my fault for not researching the product and its intended use.

I needed to replace a spring in a 1956 tape machine. There were several that fit. I eventually used a heavy pull spring and shortened it. It was exactly what I needed.This is a useful assortment. High quality springs.
