SP9600 Extension Spring 1/4″ x 1-1/2″ SS Hook Ends – HayEastdor 20pcs

Description

Product Overview

The SP9600 extension spring set delivers a reliable solution for a wide range of mechanical and everyday applications. Each spring is crafted from premium stainless steel, offering excellent corrosion resistance and long‑term durability. Measuring 1/4 inch in wire diameter and extending 1‑1/2 inches when uncompressed, the springs provide a balanced combination of strength and flexibility. The dual hook ends are precision‑formed to allow quick attachment to brackets, shafts, or other hardware without the need for additional fasteners.

Designed with a smooth surface finish, the springs glide effortlessly within moving assemblies, reducing friction and wear on adjacent components. The compact 20‑piece packaging ensures that you have an ample supply for multiple projects while keeping inventory management simple. Whether you are repairing a door latch, adjusting a curtain mechanism, or fine‑tuning a bicycle suspension, the SP9600 springs maintain consistent performance over thousands of cycles.

HayEastdor, the manufacturer behind this product, adheres to strict quality control standards. Each batch undergoes rigorous testing for tensile strength, elongation, and hook integrity, guaranteeing that every spring meets the advertised specifications. The result is a product that professionals and hobbyists alike can trust for precision‑engineered tasks.

In addition to their functional benefits, the springs are lightweight, weighing only 2.43 ounces for the entire set, which makes them easy to transport and store. The clear labeling on the packaging provides quick reference to size, material, and quantity, helping users select the right component without confusion.

Each spring undergoes a comprehensive quality inspection that includes dimensional verification, tensile testing, and hook integrity checks. The process ensures that every unit conforms to the specified 0.035‑inch wire diameter and delivers the expected extension force without premature fatigue. This rigorous approach minimizes the risk of failure in critical applications such as safety devices or precision equipment.

Usage

These extension springs excel in applications that require controlled tension and reliable return motion. Common uses include door closers, window blinds, curtain tracks, and automotive components such as throttle linkages or seat adjustments. Their stainless‑steel construction also makes them suitable for outdoor environments, resisting rust when used on garden equipment, patio umbrellas, or marine fixtures.

For hobbyists, the SP9600 springs are perfect for restoring vintage toys, repairing musical instrument mechanisms, or building custom mechanical projects. The hook ends simplify installation on pliers, piano pedals, or antique tape recorders, allowing users to replace worn springs quickly and restore original functionality.

Industrial users benefit from the springs’ consistent load characteristics in automation equipment, conveyor systems, and safety devices. The ability to maintain a steady force over a defined travel distance helps ensure that machines operate within designed tolerances, reducing downtime and maintenance costs.

For custom engineering projects, the SP9600 springs can be integrated into prototype mechanisms, robotics, and experimental rigs where precise spring rates are essential. Their consistent performance allows designers to predict behavior accurately, reducing trial‑and‑error cycles and accelerating development timelines.

FAQ

What is the load capacity of the SP9600 extension springs?

The springs are rated for a maximum static load of approximately 5 kg (11 lb) when fully extended. This rating provides a safe margin for typical door, curtain, and lightweight mechanical applications.

Can these springs be used outdoors?

Yes. The stainless steel material offers excellent resistance to rust and corrosion, making the springs suitable for outdoor equipment, garden tools, and marine environments.

How do I install the hook ends correctly?

Simply align the open hook with the mounting point, slide the hook onto the shaft or bracket, and ensure it snaps securely into place. No additional tools or adhesives are required.

Are replacement springs available for this model?

HayEastdor offers identical replacement springs under the same model number SP9600. You can order additional sets to keep spares on hand for future maintenance.

What maintenance is required for these springs?

Periodic visual inspection for signs of corrosion or deformation is recommended. If the spring shows any cracks or loss of elasticity, replace it promptly to maintain system reliability.

Are these springs compatible with other spring sizes?

The SP9600 springs are designed for specific 1/4‑inch wire diameter and 1‑1/2‑inch travel. While they can replace similar‑sized springs, using them with significantly different dimensions may affect performance.
