240Pcs 15 Sizes Compression Springs Assortment Kit, Mini Stainless Steel Extension Springs for Shop and Home Repairs, 0.39" to 1.97" Length, 0.16" to 0.24" OD, 10mm - 50mm Length, 4-6mm OD

Great to have & use as needed

I needed some small springs, these fit the bill, except unfortunately even though they are stainless steel, they are also very thin and weak good for replacing the spring in your pen or something similar that doesn't require much strength, if you need or want a sturdy spring these are not it had to go to the hardware store to buy springs the same size but made a lot stronger and the coils are thicker the coils on the springs in the kit are thin not a lot of strength

VERY POOR QUALITY SPRINGS

Lose tension easy

Good selection of springs and I was able to replace a spring on a storm door latch and another item with what was in the kit.

Comes in handy for air guns

They were ok

Good to have around the shop, used a few already, saves the drive into town.

Fine quality and a good selection of sizes and types
