uxcell Wire Diameter 0.05", OD 0.79", Free Length 2" Spring Steel Coil Extended Compressed Spring 10pcs

For some weird reason this seller doesn't provide the spring rate. The deal was really good, so I risked it hoping that I would get some stiff springs. According to my calculations, it turned out that the spring rate is approximately 0.0234 mm/g. This is softer than the stock Traxxas Slash 4x4 ultimate springs, which are of approximately 0.0195 mm/g.

Being these are made from 1.2mm wire, the strength of the spring is moderate, and can be fully compressed with my fingers. That is what I was expecting. If you want to know the inside diameter, just take the outside diameter and subtract 2 x 1.2mm, which is 17.6mm.

Opens and closes

Did not work for Fiskar pruners, but they are strong.

Very strong robust springs that are made well. Can be cut to shorten but wouldn't recommend due to the sharp end you will be left with. Very good compression spring.

Usd them to replace the return spring on baggage doors for a 2014 RV worked well.

Works well

Excellent

Pour mon projet ils ont trop de résistance, mais bon, ils sont parfait pour autre chose j’imagine 😁
