The Stainless Springpin is a Slotted or Coiled Cylindrical Fastener, Heat-Treated or Work Hardened to Achieve Optimum Toughness, Resilience and Shear Strength. In Manufacture, it is Formed to a Controlled Diameter Greater Than the Hole Into Which it is Pressed. Stainless Steel Spring Pins are Stronger Than Mild Carbon Steel Straight Pins, Taper Pins or Grooved Pins of Equivalent Sizes. Compressed as it is Driven Into a Hole, the Springpin Exerts Continuous Spring Pressure Against the Sides of the Hole, Positively Preventing Loosening by Vibration. Stainless Spring Pin Dimensions, Outside Diameters in Their Free State and Elastic Limits are Engineered so That This Self-Locking Action is Achieved in Holes Drilled to Normal Production Tolerances. No Reaming Operations are Needed to Assure a Tight Fit. No Secondary Operations are Required to Keep Springpins in Position.
