Choosing a compression spring can stall a project when the wire thickness, outer diameter, and free length all need to be right. This guide zeroes in on one specific spring option within the fasteners, springs, and industrial hardware category: a 7-11mm diameter, 10-100mm length wire compression spring. The real buying question is whether this diameter and length combination fits the light-pressure work you have in mind.
Quick Verdict
If the 9mm by 100mm size fits your assembly, this 100-pack at USD 74.18 gives you enough springs to handle a light-pressure job without ordering single pieces. It is an uncomplicated replacement choice when you already know the dimensions and simply need a supply of identical springs.
Who It Suits
This spring suits people repairing compact mechanisms, building prototypes, or maintaining jigs and fixtures where a small-diameter spring is needed. It is especially useful when you want to keep a few extras on hand and avoid stopping a run to hunt for one replacement. If you are working with high-load or heavy-duty compression, this pack is probably not the right starting point.
What Stands Out
The 0.8mm wire diameter, galvanized steel finish, and 9mm diameter by 100mm length format all line up for repeated light-duty use. It is in new condition, so it works as a clean replacement part. Because the spring is made of steel, it can hold up in ordinary shop and assembly-room environments where a protective zinc coating is helpful.
Meaningful Trade-offs
The fine wire is better for light pressure than heavy loads. If your application needs strong force or a different length, this fixed size will not stretch to fit, and you will need to measure your spring pocket carefully. Small color variations are also possible between the product photo and the actual spring due to lighting conditions, so expect the metal to look slightly different in person.
Product Note
0.8mm Wire Compression Spring
This compression spring is sold in a single pack, with steel material and a galvanized finish. Choose it when you need replacement springs of the same size and you plan to work within a light-pressure range. The limitation to keep in mind is that the fine wire is not intended for heavy-load force, so match the spring to the space and the pressure before buying.
Bottom Line
For a 100-pack of small compression springs, USD 74.18 is a practical price when you need a supply of identical replacements. This compression spring works best in light-pressure assemblies, and as long as the dimensions match your space, the pack should keep your project moving.
