20pcs Stainless Steel Small Torsion Spring, 0.5 Wire Diameter, 4.5mm Outside Diameter, 120 Degree Tiny Torsional Assortment for Repair, Woodworking, DIY Kit, Light Duty Mini Hair Clip Replacement

Used for mail flag

Needed a small spring for a hinge on one of my 3d prints and it works so great. Gunna need more soon! EDIT: I tried ordering more, using the “purchase again button, and when I received them they seem to be a different size than the last. The ones I received the first time were 4.55mm OUTSIDE diameter. Now they are measuring at 5.49 OUTSIDE diameter. I’m not exactly sure how to order the right size as there are no options and no way to contact customer support. Sad:(

They were exactly what I needed for my spider in the box that I make and sell

This did not work for what I needed it. I was trying replace the spring to a small trashcan Lid and these were way to big. They were returned

As described

These springs fit nicely on an 1/8” shaft.

This is very tiny spring with weak strength.

These aren't usable for my application because the winding is in the option direction than whats pictured also springs are flimsy and weak.
