75Pcs 25 Sizes 45-180° 304 Stainless Steel Torsion Springs Kit Saelno

Description

Product Overview

The Saelno 75‑piece torsion spring assortment is a comprehensive kit designed for makers, hobbyists, and professionals who need reliable spring solutions across a variety of applications. The set includes 25 distinct specifications, combining five wire diameters (0.5 mm, 0.8 mm, 1 mm, 1.5 mm, and 2 mm) with five bend angles (45°, 60°, 90°, 120°, and 180°). Each spring is forged from premium 304 stainless steel, a material celebrated for its excellent corrosion resistance, high tensile strength, and ability to retain shape after repeated loading cycles. After machining, the springs undergo a precise heat‑treatment process that stabilizes their geometry, ensuring consistent performance even under demanding conditions.

Every individual spring is sealed in its own clear plastic bag and labeled with a model code that matches the product’s catalog reference (TS‑25). This packaging strategy eliminates the risk of mixing sizes, speeds up the selection process, and reduces the need for re‑measurement before installation. The entire kit is compactly packed in a sturdy cardboard box measuring 8.5 × 6.14 × 0.67 inches and weighing just under 10 ounces, making it easy to store in a workshop drawer or transport to a job site.

Usage

These torsion springs excel in a broad spectrum of environments. In home repair scenarios, they can be employed to restore the tension in cabinet doors, window latches, and garage door mechanisms, providing smooth and reliable operation. Woodworkers appreciate the precise bend angles for creating custom latch mechanisms, drawer closures, and tensioned joints in furniture projects. The 304 stainless steel construction makes the springs suitable for outdoor or humid environments, such as garden tool handles, marine equipment, and outdoor lighting fixtures, where rust resistance is critical.

For the rapidly expanding world of 3D printing, the kit offers a ready‑made solution for creating spring‑loaded components, such as filament feeders, printer bed leveling mechanisms, and custom extruder designs. DIY enthusiasts can integrate these springs into robotics projects, kinetic art installations, and even wearable devices that require compact, reliable torque. The versatility of the five wire diameters and bend angles ensures that users can find a spring that matches the exact torque and deflection requirements of their specific application.

Because each spring is individually packaged, users can quickly locate the exact specification needed without rummaging through a bulk pile. This efficiency translates to reduced downtime on projects and a smoother workflow, whether you are assembling a single prototype or producing a small batch of finished products.

FAQ

What is the difference between the various bend angles?

The bend angle determines how much the spring will twist under load. A 45° spring provides a gentler torque, ideal for light‑duty applications, while a 180° spring delivers a much higher torque, suitable for heavy‑duty mechanisms. Selecting the correct angle ensures optimal performance for your specific use case.

Can these springs be used outdoors?

Yes. Because they are fabricated from 304 stainless steel, the springs resist rust and corrosion even in humid or marine environments. This makes them an excellent choice for outdoor equipment, garden tools, and marine hardware.

How do I identify the correct spring for my project?

Each spring is labeled with a model code that corresponds to its wire diameter and bend angle. Refer to the included size chart or the product listing to match the code with the required specifications. The individual packaging also displays the model code for quick visual identification.

What should I do if a spring arrives damaged?

Contact Saelno customer service within 30 days of receipt. Provide the order number and a photo of the damaged spring. Our team will arrange a replacement or issue a refund, ensuring you receive a fully functional product without delay.

Are these springs compatible with 3D‑printed parts?

Absolutely. The precise dimensions and consistent torque output make them ideal for integrating into 3D‑printed mechanisms, such as filament guides, spring‑loaded hinges, and custom actuators. Their stainless‑steel construction also adds strength to printed assemblies that might otherwise be fragile.
