## Questions & Answers

**Q: I need a spring that will fully compress with 75lbs.+ on it, but will not compress when under 40lbs. Will this spring fit my needs?**
A: The is spring has a maximum safe load of 44.20 lbs. and a maximum deflection of 1.34".

**Q: What is the total compression weight of the spring?**
A: The maximum safe load is 66.60 lbs. Maximum deflection is 1.717.

**Q: How many kilos is it rated for?**
A: I only needed to keep tension on a set screw. It did not need a specific force. They are small springs of only spring steel. I could easily compress between my hands. I also only used for a few months so could not comment on fatigue as well.

**Q: Could i easily compress this with my hands?  Please don't tell me max load or deflection - i don't know what that means!**
A: This will have to do with hand strength. The wire size, spring diameter and length along with the maximum safe work load( how much weight can be applied until the spring fails) and deflection  (how much the spring will compress down in inches) are all factors.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Good quality great price
*by B***N on April 23, 2025*

it wasn’t the size that I needed for the project I was working on. But is it well made and I’m sure it’ll come in use sometime

### ⭐⭐⭐⭐⭐ Works as advertised.
*by A***R on May 13, 2025*

I used these springs in my Yost 750-DI bench vise to fix about the only serious design flaw that vise has. The vise is designed to rotate about its base, and there's an internal locking ring that keeps it from rotating which is tightened and loosened with two bolts. This locking ring binds-up pretty easily, so I put these springs around the locking ring bolts, positioned between the locking ring and vise body. Now, when I loosen the bolts, these springs push the locking ring away from the vise body, preventing the ring from binding. I can't vouch for these springs' longevity, but they're the right size and work well enough for my purpose.

### ⭐⭐⭐⭐⭐ Dimensionally correct to what is listed.
*by D***E on March 10, 2025*

Took a chance on these springs, and they were perfect. I am using three of them on a secondary mirror holder for a telescope. The length and diameter were spot-on. The spring rate was just right for my needs to keep the mirror mount in place no mater which direction the telescope is pointed. I would buy these again for my next project.
