Steel Loop-to-Loop Spring, 50mm

This coiled steel spring features double loop ends, with an overall end-to-end length of 50 mm and an outside diameter of 15 mm. When collapsed (excluding loops), the spring body measures 24 mm. It stretches to approximately 200–230 mm and returns to its original length without permanent deformation. Ideal for studying Hooke's Law, mass-on-a-spring motion, potential energy, and simple harmonic motion in physics experiments.
