Extension Springs 5pcs Dual Hook Spring Steel Tension by FOCMKEAS

Description

Product Overview

Our 5-piece extension springs are engineered for precision and durability. Each spring is forged from high‑strength spring steel, delivering exceptional wear, heat, and corrosion resistance. The double‑hook design on both ends ensures secure attachment and easy installation on a wide range of equipment. With a wire diameter of 0.04 in (1 mm), an outer diameter of 0.39 in (10 mm), and a free length of 2.36 in (60 mm), these compact springs provide reliable tension while remaining unobtrusive in tight spaces. The polished surface finish not only enhances aesthetic appeal but also reduces friction, extending the service life of the spring in demanding applications.

Usage

These extension springs are versatile enough to serve in both household and industrial environments. Homeowners can rely on them for furniture repair tasks such as restoring the spring mechanism in chairs, sofas, recliners, and cabinet doors. DIY enthusiasts will find them ideal for custom projects, including hobbyist robotics, model building, and light mechanical assemblies. In professional settings, the springs are suitable for electrical and mechanical equipment that requires consistent tension, such as valve actuators, conveyor belt tensioners, and small lifting mechanisms. Their compact dimensions allow for seamless integration into confined spaces without compromising performance.

FAQ

What is the load capacity of these springs?

The springs are designed for moderate tension applications typical of furniture repair and light mechanical equipment. Exact load ratings depend on installation conditions, but they reliably handle repeated pulling forces within their specified dimensions.

Can these springs be used outdoors?

Yes. The high‑strength spring steel is treated for corrosion resistance, making the springs suitable for outdoor or humid environments when properly protected from direct exposure.

How do I install the double‑hook ends?

Simply align each hook with the corresponding mounting point on your equipment, then slide the hook onto the anchor. The symmetrical design ensures a firm grip without the need for additional fasteners.

Do you offer bulk pricing for larger orders?

We provide competitive pricing for bulk purchases. Please contact our sales team with your required quantity, and we will supply a tailored quote that meets your budgetary needs.

What warranty do these springs come with?

All our extension springs are covered by a one‑year limited warranty against material defects. If a spring fails due to manufacturing issues within this period, we will replace it at no cost to you.
