When you're shopping for fasteners springs industrial hardware, compression springs can be deceptively simple. The real decision is whether you want a broad assortment of small springs for varied repairs or a compact set of stronger springs for specific, tougher jobs. If you maintain a repair bench, you may want to stock up in bulk; if you are fixing one machine, a handful of correct springs might be enough. These two kits sit on opposite sides of that split, so the right choice comes down to how you work.
Quick Verdict: Choose the assortment kit when you want a broad spring collection for everyday repairs; it lists at $10.90. Choose the compact set when your work centers on a smaller number of heavier springs; it lists at $15.99.
| Product | Listed Price | Price Bar | Pack Count | What's Included |
|---|---|---|---|---|
| 390 Piece Compression Spring Assortment Kit 28 Sizes Small Steel Springs Set | $10.90 | 390 springs | 28 sizes, stainless steel, plain finish, compartmentalized case | |
| 5PCS Heavy Duty Compression Springs Spring Steel Assorted Sizes | $15.99 | 5 springs | Spring steel, assorted sizes, 1.4mm wire diameter |
Where the 390-Piece Assortment Kit Wins
It wins on breadth. With 390 springs across 28 sizes, you are far more likely to have a usable spring on hand for everyday repairs. The assortment covers small, common sizes, which makes it the kind of set you can reach for before you know exactly what you need.
Where the 5-Piece Set Wins
It wins on focus. This set gives you a smaller, simpler choice: a few springs with a 1.4mm wire diameter, positioned for industrial machinery or car-part work. If you already know the rough size, it avoids the clutter of a large assortment.
390-Piece Compression Spring Assortment Kit
This is the option to pick when your goal is to stop hunting for a single spring in the middle of a repair. It bundles many sizes with wire diameters from 0.3-0.8mm, outer diameters from 2-8mm, and free lengths from 5-30mm, so it covers small, common jobs in DIY projects, automotive repairs, industrial machinery, and household fixes. The stainless steel construction and plain finish make it easy to drop into a general parts drawer, and the labeled case keeps the sizes from getting mixed up. The main limitation is the size range: these are small springs, and if a job calls for a thicker spring, the kit may not have what you need. It works well as an all-around collection, but it is not a substitute for a dedicated replacement spring.
5-Piece Heavy Duty Compression Springs
This compact set is aimed at situations where you know you need a heavier spring and only need a few. It comes with five compression springs in assorted sizes, made from 65Mn spring steel with an untreated surface. The intended uses point toward industrial machinery, car parts, and various parts, so it fits maintenance and repair jobs that call for a heavier spring. The trade-off is the pack count: five springs gives you very little room for trial and error, and the assorted sizes may not line up exactly with the specific replacement you need. For quick, high-duty fixes, this is the more focused option; for a general collection, it is too limited.
Final Choice by Use Case
- For a well-stocked general repair drawer: choose the assortment kit. Its broader assortment makes it the practical daily pick.
- For a specific industrial machinery or car-part repair: choose the compact set. The focused pack count and compact format align with jobs that need fewer, tougher pieces.
