Extension Spring Prime-Line SP 9600 Nickel 1/4 inch x 1-1/2 inch 2

Description

Product Overview

The Prime-Line SP 9600 extension spring is engineered for versatility and durability across a broad spectrum of mechanical and consumer applications. Constructed from tempered spring steel, the spring offers a consistent 0.035 GA wire thickness that balances flexibility with strength, ensuring reliable retraction after each stretch. Its nickel‑plated finish not only provides an attractive, polished appearance but also delivers superior corrosion resistance, allowing the spring to perform reliably in both indoor and outdoor environments, including humid or marine settings.

Measuring 1/4 in outside diameter and 1‑1/2 in free length, the spring is compact enough to fit into tight assemblies while still delivering a maximum safe load of 8.46 lb. The open‑end, single‑loop design simplifies installation, enabling users to attach the spring to fixed or moving components without the need for specialized tools or complex procedures. This design also facilitates easy removal for maintenance or replacement, reducing downtime in critical applications.

Each package contains two identical springs, providing redundancy for projects that require multiple points of tension or allowing users to keep a spare on hand. The springs are supplied with clear line‑art drawings that detail dimensions and recommended mounting points, ensuring that engineers and DIY enthusiasts alike can verify compatibility before purchase. Backed by a one‑year warranty against manufacturing defects, Prime-Line underscores its confidence in the product’s quality and longevity.

Usage

These extension springs excel in a variety of settings, from household appliances to industrial machinery. In the home, they can be employed to restore tension in garage door mechanisms, assist in the operation of drawer slides, or provide the necessary force for custom‑built toy projects that rely on spring‑loaded motion. Their compact size and robust load capacity make them suitable for automotive applications such as throttle return springs, clutch pedal assist, or suspension components where precise force curves are essential.

Marine environments benefit from the spring’s nickel plating, which resists saltwater corrosion, making it an excellent choice for boat hatch latches, fishing gear, and marine instrument housings. In professional toolkits, the springs serve as reliable components for pneumatic tools, mechanical presses, and custom‑fabricated devices that require consistent extension force. Their ability to handle up to 8.46 lb of load ensures they can sustain the demands of heavy‑duty tasks without permanent deformation.

Installation is straightforward: the open ends allow the spring to be slipped onto a shaft or pin, and the tension can be adjusted by selecting the appropriate mounting distance. For applications requiring precise deflection, users can calculate the required stretch based on the spring’s known constant, ensuring optimal performance. The springs’ versatility also extends to educational settings, where they can demonstrate principles of elasticity, Hooke’s law, and mechanical advantage in physics labs.

FAQ

What is the maximum load this spring can safely handle?

The SP 9600 is rated for a maximum safe load of 8.46 lb. Exceeding this load may cause permanent deformation or reduced spring life. For applications requiring higher loads, consider a spring with a larger wire diameter or a different model.

Can these springs be used in marine environments?

Yes. The nickel‑plated finish offers excellent resistance to saltwater corrosion, making the springs suitable for marine applications such as boat hatch latches, fishing gear, and other equipment exposed to moisture.

How do I determine the correct spring length for my project?

Measure the distance between the mounting points where the spring will be installed. The free length of the spring is 1‑1/2 in; you can stretch it to achieve the desired deflection, ensuring the load does not exceed 8.46 lb. Refer to the line‑art drawing for exact dimensions and recommended mounting configurations.

Is any special tooling required for installation?

No special tools are needed. The open‑end design allows the spring to be slipped onto a shaft, pin, or rod directly. In most cases, a simple pair of pliers can be used to position the spring if space is limited, but the process is generally tool‑free.

What does the one‑year warranty cover?

The warranty covers manufacturing defects in materials and workmanship. It does not cover damage caused by improper installation, misuse, or exposure to abnormal conditions such as extreme temperatures or chemical corrosion beyond the intended use. If a defect is identified, contact Prime‑Line customer service for a replacement.
