PRIME-LINESP 9901 Spring Assortment, Spring Steel Construction, Nickel-Plated Finish, 20 Extension Springs, 64 Compression Springs (Single Pack)

Great price and variety of spring types and sizes.Lost a spring from our ryobi weed wacker head (bad design causes you to have to open the head to get new line fed into the trimmer head) and Ryobi said they would not sell or send me a new spring since I opened it, that I had to buy a new $24 trimmer head. I won't buy Ryobi stuff again, but this set of springs had a spring size that worked and we are in trimming business again - thank you.

I had ordered this for a little project, and they are fantastic little springs, but most of them require way more force than what my project can muster.If you need small but strong springs, these should work great!

I needed a few compression springs of varying sizes for a prop replica I'm working on and figured I might as well give this pack a shot since it cost less than I would be spending at my local hardware store to pick out the 5 individual springs I would need($4.37 with Prime Add-On shipping at time of purchase), and boy am I glad I did! Attached is a picture of the assortment of springs I received, and although I assume this will vary from package to package, if the assortments are all generally the same as mine I think the mfr did a great job selecting close to most useful assortment in a pack like this. The great majority of the springs are compression springs, perfect for my needs and most other projects. They span from extremely light to extremely heavy resistance curves, so extreme that I would call the lightest and heaviest springs specialty items which makes them all the better to have on hand rather than having to hunt for them when I need them. The springs all have a pleasant black, slightly metallic finish, somewhere between brushed nickel and black chrome which makes them blend in very well rather than stand out. Only time will tell just how well the springs keep the resistance curves, but from the ones I've tested by hand so far they don't seem to work harden any measurable amount and a set of calipers measure only a 12 micron average loss of length after 50 full compression cycles on 10 springs which is well within the margin of error. Overall I couldn't be happier with my purchase. These will be great to have on hand in the shop.

Previously I was looking at the single size spring of this brand and I was not sure which to use. Then I looked at the catalog and saw that the brand offers an assortment. That was the best decision made. I could source any spring I need from this manufacturer that I need. The only thing is the spring are not labelled in any form so I would have to do some measuring to determine the spring I need. I don't need the springs right now but playing with them is fun and I'm sure I could always pick the one I need.

Did not have what needed in this box of tiny springs. However I improvised and made one similar to what I needed for my replacement RV step mat spring. Lots of extras for future projects or needs. All good.

Lots of various compression and extension springs, exactly as other reviewers have noted. I was pleasantly surprised by the quality given the low price. I was also surprised that there are some fairly heavy duty compression springs (i.e. difficult/impossible to manually depress). But I was a little disappointed that there weren't any heavier extension springs. Overall, great set that will definitely come in handy.

A lot of springs, but the ones pictured in the ad with a hook on both ends are not in the package. I had to garbage together to cut springs to make my loppers sort of work.

I needed a variety of springs for a Girl Scout engineering project, with lots of choices and lots of springs. Each girl was able to build a "Leap-Bot" and try several springs, completing the engineering badge. With the pandemic, we can't share a single box with a few springs, and I was able to give each girl 3 springs in her own baggie to build with.

Buenos resorte

there is a great many different kinds and strengths of springs in the package, not the one i needed of course but it i still a great buy, a real good assortment of springs, i am after a extension spring about .5 of a mm in diameter and about 1 inch long. if anyone can help with this it would be appreciated

Solid product, exactly what you'd expect. Variety pack of numerous springs for both compression and decompression forces.

Was able to find a spring that worked to put my wheel back on my shopping cart . So many different springs cuts down on the necessary ones a person can use or modify if need be . Was hard to tell in the jumbled pkg if the one I needed was there so I took my chances . I won and my cart is ready to roll :-)

Not really much tention on the springs..I was able to place one inside another and sort of make do....Delivery was supposed to be next day..but took a week..
