How do I choose the right force rating for a gas spring?

Match the force rating (in Newtons or lb-force) to the weight your application must hold open or support, factoring in the mounting leverage and angle. Product listings state the nominal force; select a value that holds your load steadily without pushing it past the intended position.

What measurements should I check before buying a replacement gas strut?

Check the extended length, compressed length, stroke, rod diameter, and end-fitting type against your existing unit. Listings provide these dimensions so you can confirm the new strut fits the same mounting points and travel range.

Are these Cilky springs suitable for pen repair?

Yes, reviewers have confirmed these springs work as replacements for pen mechanisms. Their precise dimensions and elasticity make them a good fit for restoring functionality to many types of pens.

What is the material of these compression springs?

These springs are made from 304 stainless steel, known for its high elasticity, smooth surface, and excellent resistance to corrosion and rust, ensuring a reusable and long service life.

Can I use these springs for heavy-duty applications?

No, these springs are designed for light-duty applications such as pen repair, toys, and electronic components. They are not intended for heavy-duty industrial use or supporting significant weight.
