When a repair stalls because you don't have the right spring, the real question isn't just price-it's whether you need a straight push-back or a twisting return force. In the world of fasteners, springs, and industrial hardware, two very different options face off: a single 300mm compression spring and an 80-piece torsion spring assortment. One is a precise replacement for a linear coil; the other is a rotational-force kit meant for hinges, arms, and doors. Here's how to pick.
Quick verdict: If you need one exact long coil to push a component back, the single compression spring at $3.69 is the low-cost, direct answer. If your work involves parts that twist, the 80-piece torsion spring kit at $11.39 gives you 20 sizes and multiple angles for a modest outlay.
| Product | Price | What you get | Price level |
|---|---|---|---|
| Compression Spring (300mm) | $3.69 | Single open-end spring steel coil | |
| Torsion Spring Assortment (80 pcs) | $11.39 | 20 sizes, 60/90/120/180 degree |
Where the compression spring wins: It's the economical pick for a single linear repair. The 300mm length, open ends, and spring steel material make it a straightforward candidate when you already know the coil you need and don't want extras you'll never use.
Where the torsion assortment wins: It's the problem-solver for rotational tasks. The 80-piece count, 20 sizes, and 60/90/120/180 degree angles cover a broader range of twist-action repairs, and the stainless steel finish resists rust with a polished look.
Compression Spring Various Size 2-42mm Diameter & 300mm Length Pressure Small

If your repair calls for one long coil that pushes back, this compression spring is the direct candidate at just $3.69. The 300mm length and open ends make it suitable for linear force applications, and the spring steel build keeps the price low. It comes as a single piece in a self-sealing bag with carton packaging. The limitation is that you're getting one spring, not a range-if the diameter isn't right for your assembly, you'll have to source another size. And because this is a compression spring, it's not meant for twisting loads. It's a simple, low-cost way to tackle a specific push-back repair without paying for a multi-piece kit.
80PCS Torsion Spring Assortment Kit, 20 Sizes 60/90/120/180 Degree Small Torsion

The torsion assortment is the right move when you deal with rotating parts. You get 80 pieces across 20 sizes, with angle options of 60, 90, 120, and 180 degrees, all in a stainless steel finish with a polished surface. The 7-ounce kit is compact enough to keep on a workbench for hinges, door handles, and 3D printer arms. The trade-off is that these springs provide rotational force only-they won't replace the long compression spring if you need straight-line push-back. The thin manufacturing oil coating is normal for stainless steel to guard against rust, but you should be comfortable handling lightly oiled springs. For general twisting repairs, this kit's variety is hard to match at $11.39.
Final choice by use case: Pick the compression spring when you need a single 300mm coil for a linear push-back repair and want to keep the cost to $3.69. Pick the torsion assortment when you need 80 stainless steel springs in 20 sizes with 60/90/120/180 degree angles for $11.39, especially if hinges or rotating arms are your recurring projects. If your repair list includes both kinds, the two purchases together-$15.08-give you a dedicated long compression spring plus a full rotational assortment.
