40 Pcs Stainless Steel Tiny Torsion Spring 0.5 Wire Diameter Outside Diameter 4.5 mm Mechanical Small Torsion Spring 120° Deflection Assortment for Repair Woodworking DIY

I used multiple springs sliding the loop coil over a shaft to then acct as a hinge in a small area. Words perfectly when using multiple springs, which adds (or subtracts, as necessary) the amount of spring tension I needed.

I purchased this item for you and a product prototype. I had to make a guess as to whether it would be strong enough for my purposes. As it turned out, it was not. If there was a reference to its strength, I missed it. Perhaps, it could be placed better in the description. I’m sure the product itself works as intended. There’s nothing wrong with it. It was just too weak for my purposes.

Had a door latch that needed a new spring, these seemed the right dimensions. More than I needed, but inexpensive. Turned out I needed to install 2 of them, side by side, to get the spring tension just right. Cut them to just the right size. If they don't last, I've got plenty more left in the package.

Trying to fix the lid of my plastic office trash can, but these were not strong enough to do the job.

They work as supposed to, I had just hoped they would have had a little more tension.
