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.
