RS PRO Steel Extension Spring 27.2 mm Free Length x 4 mm Outside Diameter 751-663

RS PRO 751-663 Steel Extension Spring is a high-quality mechanical component designed with a free length of 27.2 mm and an outside diameter of 4 mm. Made from high tensile strength piano/music wire, it features a right-hand (clockwise) helix and looped ends for secure attachment in mechanical applications.

The spring is engineered to absorb and store energy, providing resistance against pulling forces, with an initial tension of 4.26 N that can be manipulated to meet specific mechanical design requirements. It offers a spring rate of 0.06 N/mm and can extend to a maximum length of 95.7 mm, making it suitable for a variety of dynamic uses.

Manufactured under strict standards including DIN 17223, RoHS, and BS 1408 CR3, this spring meets rigorous quality and environmental compliance. The oiled finish further ensures resistance against corrosion, enhancing the product lifespan in demanding conditions.

Applications for this extension spring include automotive interiors and exteriors, garage door assemblies, vise-grip pliers, carburetors, trampolines, washing devices, and farm machinery, making it a versatile choice for heavy-duty and precision mechanical tasks.

The country of origin is United Kingdom, reflecting high manufacturing standards and quality assurance. Manufactured from high tensile strength piano/music wire with looped ends. Designed to absorb and store energy during mechanical extension.
