Last updated Aug 17, 2026

Choosing a compression spring assortment often comes down to one tension: do you want many sizes on hand for unexpected repairs, or do you need a specific spring spec you can order in quantity? In fasteners springs industrial hardware, pack size and listed price are usually the first two filters. Here are four compression spring options that approach that decision from different angles.

Quick take

For most mixed small repairs, the 380PCS spring set earns the first look with 23 sizes and a USD 14.99 price. The 300 Pcs kit sits at USD 11.93, the lowest listed price in the group, and brings 30 sizes. A 225-piece set is the compact middle path, and a dedicated 100-piece compression spring listing is the specialist pick.

Small & Tiny Stainless Steel Compression Springs Assortment

380PCS Stainless Steel Compression Springs Assortment Kit - Small & Tiny Springs

This kit is the piece-dense generalist of the four. It holds 380 springs across 23 sizes in the small and tiny range, with wire diameters from 0.3mm to 0.7mm. That coverage makes it easy to swap a pen spring, tighten a wobbling fixture, or grab a replacement during a workshop project without waiting for a specialty order. The stainless steel construction is a solid match for humid garages and outdoor storage. Because the sizes stay small, it will not help when you need a large-diameter or heavy-duty compression spring. Choose it when variety matters more than any single exact dimension.

The kit flips the quantity formula: 300 springs organized into 30 sizes, with 10 pieces per size. That gives you the broadest length selection in this group, from short 0.39-inch lengths to longer 1.19-inch versions, while staying at the lowest listed price among the four. It is a practical companion for shop and home repairs where you want many possible sizes without committing to a big total inventory. The catch is per-size quantity: 10 springs per size can disappear fast if you are repairing many identical items. For occasional pick-and-sort projects, it is hard to beat.

300 Pcs Compression Springs Assortment Kit, Stainless Steel Springs,Mini Spring

This kit brings the most curated option. Instead of a bin of dozens of types, it presents 15 sizes with 15 springs per size, so you know exactly what you're stocking. The provided dimensions step up in a neat progression from a 0.3mm wire, 4mm outer diameter, 10mm length class to longer small springs, so you can match a specific miniature spring in tight spaces. The limitation is variety: with 15 sizes, you'll cover common needs but will still chase odd sizes more often. It's the better second kit for a drawer that needs a disciplined, low-quantity stainless steel assortment.

Compression Springs Wire Dia 0.5mm OD 3mm 304 Stainless Steel Vibration Damping

This listing takes the opposite approach. It packages 100 compression springs built to a single spec: 0.5mm wire, 3mm outer diameter, in 304 stainless steel with closed ends. Closed ends let the spring sit flat while transferring force, and the consistent spec makes this a repeatable replacement part rather than a grab bag. You pay more because you're buying one known size in quantity. If that OD and wire diameter fit your equipment, it removes guesswork; if they don't, you'll need to look at different dimensions. This is the pick for a technician with a clear spring requirement.

Final recommendation by use case

For a general-purpose workshop or home repair drawer, the large spring assortment is the first choice: a wide mix of small sizes at a modest price. If you want maximum size coverage from a multi-pack at the low end of this group, go with the mini compression assortment. For a tidy, predictable inventory of common miniature sizes, the 15-size mini stainless steel assortment makes sense. When the job is a known, repeated replacement using a 0.5mm wire / 3mm OD 304 stainless steel spring, the dedicated spring set is the practical order.
