Elastic cylindrical pin, also known as the spring pin, is a headless hollow column shape, axial slotting, two end chamfering, used for positioning, connecting, fixing between parts;Good elasticity and shear resistance are required. the outer diameter of such pins is slightly larger than the assembly aperture. Elastic cylindrical pin classification 1) lightweight elastic cylindrical pin 2) heavy duty elastic cylindrical pin the main difference between light and heavy is the thickness of the material and the width of the chamfering, heavy spring pin material thickness and the width of the chamfering are larger than the light. Elastic cylindrical pin with teeth 1) lightweight elastic cylindrical pin 2) heavy duty elastic cylindrical pin the shape of the elastic cylindrical pin is similar to that of the common elastic cylindrical pin. Roll elastic cylindrical pin 1) light roll elastic cylindrical pin
