Choosing a compression spring for your fasteners springs industrial hardware setup usually comes down to two questions: how much load does the spring need to carry, and what environment will it live in? The CooBetter Compression Spring 1.5mm Wire Diameter 15-100mm Length Pressure Small OD 8-25mm and the GooBetter Compression Springs Wire Dia 0.5mm OD 3mm 304 Stainless Steel Vibration Damping solve those questions in different ways. One is a thicker steel spring with a wide outer diameter range; the other is a thinner stainless steel spring with closed ends for light vibration-damping duty.
Quick Verdict
If your primary need is a compression spring with a 1.5mm wire diameter and the flexibility to span outer diameters from 8mm to 25mm, the CooBetter spring at $20.89 is the straightforward choice. If you need a lighter 0.5mm wire spring for vibration damping in appliances, lamps, switches, and similar equipment, the GooBetter 304 stainless steel spring set at $111.69 gives you 100 pieces with closed ends for efficient force transfer.

Where Each Spring Wins
CooBetter 1.5mm Compression Spring
- Wins for heavier pressure and size versatility. With a 1.5mm wire diameter and outer diameters from 8mm to 25mm, it covers larger spring pockets and more substantial loads.
- Wins on price. At $20.89, it is the lower-cost way into a working compression spring.
GooBetter 0.5mm 304 Stainless Steel Compression Spring
- Wins for light-duty vibration damping. The 0.5mm wire and 3mm outer diameter fit small, low-load applications.
- Wins on material and end design. The 304 stainless steel construction and closed ends support efficient force transfer and reduced tangling.
- Wins for quantity. The set includes 100 pieces, which helps when you need spares or multiple springs.
Product Notes
CooBetter Compression Spring 1.5mm Wire Diameter 15-100mm Length Pressure Small OD 8-25mm

The CooBetter spring is built around a 1.5mm wire diameter with outer diameter options from 8mm to 25mm and lengths from 15mm to 100mm. That range makes it a practical pick when you need a compression spring for a small-pressure job and you are not locked into a single size. At $20.89, it also keeps the cost of getting started low. The material is spring steel, so it is a conventional steel spring rather than a stainless variant. The main limitation is the size envelope: the smallest outer diameter this product offers is 8mm, and the wire is 1.5mm, so it will not suit a particularly tiny or light-duty spring pocket. If your project calls for a 0.5mm wire spring with a 3mm outer diameter, this is not the one to buy.
GooBetter Compression Springs Wire Dia 0.5mm OD 3mm 304 Stainless Steel Vibration Damping

The GooBetter set is aimed at the opposite end of the spectrum. Each spring has a 0.5mm wire diameter, a 3mm outer diameter, and lengths up to 305mm, making it a more precise spring for compact assemblies. The material is 304 stainless steel, and the ends are closed to improve force transfer and reduce tangling, which matters for light vibration-damping applications like appliances, lamps, electrical switches, fitness equipment, and toys. You get 100 pieces for $111.69, so it is the higher-priced option, but the quantity gives you several springs to work with at once. The limitation is that the wire is only 0.5mm and the outer diameter is just 3mm, so it is not meant for heavy-load or large-diameter pressure work.
Final Choice by Use Case
Pick the CooBetter 1.5mm compression spring if you need a heavier-duty spring with a wider outer diameter range and a lower purchase price of $20.89. Pick the GooBetter 0.5mm 304 stainless steel compression spring if you need 100 light-duty springs for vibration damping in compact assemblies and are comfortable with the $111.69 price.
