Choosing the right compression spring for fasteners springs industrial hardware work can feel like a guessing game: pick too thin a wire and the spring collapses; pick too wide an outer diameter and it won't fit the bore. The two options here take two very different routes. The CREEYA assortment gives you a broad collection of tiny stainless steel springs, while the CooBetter spring offers a thicker spring steel wire with a wider dimension range. Your decision really comes down to whether you need variety for small mechanisms or a specific, larger spring for a defined job.
Quick Verdict
If you are stocking a repair drawer for small appliances and prototypes, the CREEYA assortment gives you more usable spring sizes for the money. If you already know the exact wire diameter and dimension range you need, the CooBetter spring is the more direct purchase. The table below lines up the key differences.

Where Each Product Wins
Pick the CooBetter spring when:
- You need a longer length option and an outer diameter beyond the miniature range.
- A heavier, thicker wire is important for the force you're applying.
- You're replacing a known spring in a larger assembly and want a defined specification.
Pick the CREEYA assortment when:
- You're working on miniature mechanisms with compact outer diameters.
- You want multiple size options in one kit so you can test and compare.
- You'd rather fill a repair drawer with variety than commit to one spring size.
Product Notes
CooBetter 1.5mm Compression Spring
The CooBetter 1.5mm compression spring is the more specialized pick in this comparison. Its wire diameter is the defining attribute, and the listed 8-25mm outer diameter range with a 15-100mm length range makes it useful when you need a spring that reaches beyond the miniature scale. For someone replacing a known spring in a larger assembly, this is easier to specify than sorting through an assortment kit. The limitation is that its smallest outer diameter is 8mm, so you're out of luck for very small bores. And because this is a defined wire size, you'll need to know your exact target dimensions before ordering.
CREEYA 225-Piece Compression Springs Assortment Kit
The CREEYA assortment approaches the same problem from the opposite direction. Instead of one wire specification, it gives you 225 pieces that span a range of small spring dimensions, with the listed sizes starting at 10mm lengths and 4mm outer diameters. That makes it a practical first kit for small mechanisms. The practical edge is that you can test a size and move on to the next if something doesn't fit. The limitation is that all of these springs are on the miniature side, and with a maximum outer diameter of 6mm and maximum length of 30mm, it's not built for the larger bore sizes the CooBetter spring handles.
Final Choice by Use Case
If you're stocking a repair kit for small mechanisms and want a wide selection at a lower price, the CREEYA assortment kit is the one to buy. At $14.15, it's the lower-priced option, with about $6.74 separating it from the CooBetter spring's $20.89. If you have a specific replacement that needs the larger size range of the CooBetter spring, the CooBetter option at $20.89 is the more precise fit. For one-off replacements, go with CooBetter; for tinkering and prototyping, the CREEYA kit gives you more spring for the money.
