Compression Springs Assortment Kit, 15 Different Sizes 225pcs Mini Stainless Steel Springs for Repairs, 0.39 to 1.18 Length, 0.16 to 0.23 OD, 10mm - 30mm Length, 4-6mm OD

I need small springs of varied length and good force to repair an electrical slip ring in a rotating tree stand. Ok, its obscure. LOL This kit had a selection of lengths and diameters that allowed me to test fit different options. In the end, I found one that was big enough to be retained but small enough to fit and long enough to exert sufficient force when compressed 50%. My only suggestion would be to somehow note the spring compression force in oz or lb or N. Had they been too light, they wouldnt have worked. Accuracy is better than luck.

I like that its a box of springs and it worked for what I needed

Make sure you are opening from the right side with this box. Not only is it a mess to sort if you open it from the wrong side, but its really not always obvious at first which one it is. The cardboard goes on top, the transparent side is on the bottom. Otherwise, it does the trick very well, but the 3 stars rating comes from the horrible package.

I used this to replace a broken spring in some jewelers pliers. These are SO flimsy, one barely works. If you need a sturdier wire I recommend looking elsewhere. I mean, they kind of work but Im afraid it will fall out easily, but it was cheaper then another $40 pair of pliers.

I was looking for a particular spring to repair my fishing reel. Unfortunately what I needed was not in this kit. Still a good assortment to have in my shop parts supply.

Small useless pieces. Pictures were very deceiving

Tolles Paket mit einwandfreien Federn. Preis-Leistung passt. Nicht nur 3 Windungen sondern so wie es sich gehört

I like the assortment kit, it will work out great !

Used a spring on a hydraulic lifter, it worked.

I needed one spring and got 225. Great little kit to have near your tool box. Buy it.
