The Spring Pin has many advantages as a fastener some of which are listed below: Replacement for Solid Pins, Taper Pins, Cotter Pins, Split Pins, threaded items and many other methods of fastening previously used. Excellent shear strength properties - Tests show that Spring Tension pins to be approximately 10% stronger as well as 10% lighter than that of mild steel solid pins. With diameters slightly larger than that of the hole size they provide a tight spring fit into the hole providing a tight grip along the pins length. By virtue of their design they offer constant on-going pressure making them resistant to vibration. Costs are reduced by the elimination of reaming and threading. Simply drill and insert. Pin shear strength can be increased further by inserting one pin inside another. Pins are generally manufactured from carbon spring steel and supplied with a self / plain finish. However Caleb is able to offer stainless steel parts on request and also offer plated finishes such as electro zinc and passivate or Deltatone. Note! Parts that are electroplated may be subject to hydrogen de-embrittlement and in extreme cases fracture may occur. Caleb can take no responsibility for this and is carried out at customers own risk. Please note! If parts are supplied plated this will increase the diameter of the pin and some interlocking may take place either in the plating or packing process.
