The Ultimate Mechanical Solution for Repairs and Prototypes
Whether you are fixing a lawnmower, upgrading a mechanical keyboard, or building a STEM project, the 200pcs Steel Spring Assortment provides the versatility you need. In any mechanical repair, the spring is often the smallest yet most critical component. This kit ensures you have the exact size and tension required to restore functionality immediately.
Engineered for Durability and Performance
Each spring in this set is manufactured from high-grade steel, treated for rust resistance and long-lasting elasticity. Unlike cheap alternatives that lose their "springiness" over time, our springs maintain their mechanical properties even under repetitive stress. The silver finish provides a professional look that integrates seamlessly with electrical hardware and automotive components.
Organized, Labeled, and Ready to Use
Time is money in any repair job. That’s why this kit comes in a transparent, compartmentalized PP storage box. The lid features a clear size chart corresponding to each section, allowing you to identify the correct dimensions (diameter and length) at a glance. No more digging through a junk drawer—just professional-grade organization.

FAQ Section
FAQ Section
Q: What is the difference between the compression and extension springs in this kit?
A: Compression springs (Pressure) are designed to resist being compressed, while Extension springs (Pull/Tension) are designed to resist being stretched. This kit includes both to handle any mechanical requirement.
Q: Are these springs suitable for outdoor use?
A: Yes, the steel is rust-resistant; however, for prolonged exposure to saltwater or extreme moisture, we recommend applying a light coat of machine oil.
Q: Will the box keep the springs separated during transport?
A: Absolutely. The PP storage box features tight-fitting dividers that prevent the different sizes from mixing, even if the box is turned upside down.
