22pcs Extension Springs Assortment Kit, Length 5cm 6cm 7cm 8cm 9cm 10cm 11cm 12cm, Wire Diameter 1.2mm, Outside Diameter 12mm, Mechanical Strong Extension Springs with Hook for DIY Repair Replacement

Note that on this listing, the quantity also determines the size. Larger quantities equals smaller springs and less quantities is bigger springs. You got to figure out what you need for your project. I got the 22-piece set which is in the medium size of what this seller is offering. These springs are substantially bigger than a lot of the super tiny springs sold in many assortment kits. But they are way smaller than something like trampoline springs which are huge and strong. It was honestly kind of hard to find this medium size type of spring. I have included some common household items with the springs to give a general idea of the size. They look nice and shiny with no signs of rust, but I don't know if they're actually stainless steel or not. I won't be using them outside or in a wet environment so that doesn't really matter to me. They look to be good quality.

Easy to find in the box, just the right size. Very good storage box.

They look good just that they are too strong for the purpose I bought them for.

It met my expectations Very durable

This is the best assortment of springs I've seen in years. Well worth the reasonable price!

Worked perfectly. I replaced a spring on the hood latch on my car and it was just what was needed. I was unsure of the size I needed so I ordered the assortment.

Too many springs.

A good product with a nice selection of sizes. Have used several in an outdoor project and they’ve held up well for over 6 months now.

utile pour les dépanner

Buena compra, buen surtido.

Schnelle Lieferung, alles Bestens

Great springs. I fitted 2 on my bike exhaust and a year after they haven't got rusty or weakened.

Besoin d'un ressort pour mon robot tondeuse pour le bouton STOP: cela parait bête, mais c'est un ressort d'une dimension courte, mais nécessitant une pression forte. Le ressort d'origine n'est trouvable quasi nul part, et la commande à l'étranger coute plus de 15€. Donc je me rabats sur une boite de plein de ressorts, espérant que cela convienne. Première commande sur AMAZON: ressorts trops fins, pas de pression, etc... retour à l'envoyeur. Mais avec cette boite: miracle! les ressorts font 0.9mm de diamètre, donc c'est du solide. Pour comparaison, les autres produits font généralement 0.6mm et cela fait une vrai différence. Ici la tension reste permanente, le ressort conserve son pouvoir de traction même si il est utilisé régulièrement. Je me retrouve avec une boite de qualité, et d'ailleur mon deuxième robot tondeuse a eu le même soucis, et là de fait j'ai une collection de ressorts de remplacement! :) je valide vraiment cette boite, pas chère, bien pratique!! (et souvent au même prix voire moins chère que les produits concurrents, et là différence de qualité ici est flagrante!) Bon achat! :)
