Global standard for coil spring pins "SPIROL products" SPIROL PIN
<Spiral Roll Pin> The spiral roll pin is a spring pin made by winding a thin plate with spring properties, such as steel or stainless steel, in a spiral shape approximately 2+1/4 times, and it has guides at both ends to facilitate easy press-fitting into the counterpart's hole. - After press-fitting, it is securely held in all directions, providing uniform shear strength, making it less prone to metal fatigue. - Since no fasteners are required, it reduces processes and lowers costs. - The pin itself has elastic force and is structurally strong against vibration and impact. ++ Pin issues are a common challenge for engineers ++ - Caused by fatigue after assembly - Caused by insufficient force under load - Deformation of the counterpart's pilot hole - Destruction of the pilot hole due to pin rigidity under load, etc. These issues with composite pins have been resolved with the spiral roll pin. → The spiral roll pin is installed in a way that overlaps naturally rather than interlocking, making it ideal for automation. → The pressure is distributed throughout the pin, making it less likely to cause metal fatigue. Additionally, we can supply aluminum insert collars, dowel pins, spacers, shims, cutting nuts, solid pins, resin inserts, disc spring washers, and specialized equipment.
