Looking for small compression springs? The challenge is deciding between a broad assortment kit and a purpose-built micro spring set. The four options here sit in two clear price tiers: the assortment kits are grouped together, while the micro spring kit is a much higher-priced specialist choice. That price gap reflects a real difference in spring size and intended use.
Quick take
For most workshop tasks, the 390Pcs Small Compression Springs Kit is the practical pick: it combines labeled storage, a reusable case, and springs in a range of sizes. If your work involves watches, electronics, or precision tools, the Micro Compression Spring 304 Stainless Steel set is the specialist choice.

Before you choose
Think about the smallest and largest spring dimensions you need. The assortment kits are built for quick fixes, craft projects, and light mechanical repairs; you get a range of sizes in one case. The micro spring set is for precision work where a specific wire diameter and outer diameter matter more than the total number of springs. At the low end, you get dozens of springs at a modest per-piece cost; at the high end, you get fewer but precisely specified components. For quick fixes where a close-enough size works, an assortment is faster. For a repair where the spring has to fit a tight channel and push with a predictable force, the micro kit's defined dimensions matter more. The right choice comes down to the diameter of the space you need to fill and how much precision the job requires.

Product notes
390pc Compression Spring Assortment Kit 28 Sizes Stainless Steel Small Springs
This 390-piece kit spans 28 sizes, with wire diameters from 0.3mm to 0.8mm and outer diameters from 2mm to 8mm. The stainless steel construction, round head style, and plain finish make it a versatile choice for small mechanical repairs, crafts, and workshop fixes. It weighs 6.7 ounces, so it is easy to keep in a drawer or bag. The assortment is best for general work rather than a single, exact-size replacement spring. If your project requires precise length or force specifications, you will likely need to measure and select by hand rather than rely on a per-size chart.
380PCS Stainless Steel Compression Springs Assortment Kit - Small & Tiny Springs
The 380-piece set covers small and tiny springs, from pen-repair sizes to small craft springs. It comes in a compact case measuring 7.4 x 5 x 0.65 inches and weighs 6.38 ounces, making it easy to store next to your tools. The stainless steel material works for general garage and workshop projects. Because this kit is explicitly small and tiny, it won't help if you need larger compression springs for heavy-duty applications. For someone focused on miniature repairs and crafts, it's a tidy alternative to the 390-piece variations.
Micro Compression Spring 304 Stainless Steel 0.1mm Wire Tiny Miniature 5-25mm
This set takes a different approach. The wire is 0.1mm thick, outer diameters range from 0.8mm to 1.4mm, and lengths span 5mm to 25mm. It is built for watches, electronics, precision tools, and repair DIY, with closed and squared ends plus a polished, bright finish. CNC winding gives stable force distribution for miniature mechanisms. Images are zoomed in for clarity, so because the springs are extremely small, you need to follow the SKU text parameters rather than judge size from photos. This is the option to choose when you need a defined micro size and corrosion-resistant 304 stainless steel, not a mixed assortment.
390Pcs Small Compression Springs Kit 28 Sizes Assorted Coil Spring
This 390-piece kit contains 28 sizes, with wire diameters 0.3-0.8mm, outer diameters 2-8mm, and free lengths 5-30mm. A reusable case has labeled compartments, so you can reach for the right size without sorting through loose springs. The 304 stainless steel is smooth, strong, and corrosion-resistant. This is the most practical general-purpose option in the price comparison because it combines a wide diameter range, labeled storage, and the lowest price. The trade-off is that the smallest wire size is 0.3mm, so it does not cover the 0.1mm micro range.
