Metal expansion nuts, often referred to as expansion anchors or expansion inserts, are specialized fasteners that expand when a bolt or screw is threaded into them. They typically consist of a cylindrical body with slits along its length or an expandable design that facilitates outward expansion. The main purpose of these nuts is to create a secure grip within a substrate, such as concrete, wood, or metal, thereby preventing loosening due to vibrational forces, temperature fluctuations, or stress.

  • Resistant to steam, petroleum oils, amine corrosion inhibitors, and hydrogen sulphide. 
  • Over time, the rear shock absorber oil seal can degrade and become worn out. This can be due to normal wear and tear, exposure to harsh environmental conditions, or simply the passage of time. When the seal begins to deteriorate, it can lead to oil leaks and a loss of damping performance. This can cause the vehicle to become unstable and unsafe to drive This can cause the vehicle to become unstable and unsafe to drive This can cause the vehicle to become unstable and unsafe to drive This can cause the vehicle to become unstable and unsafe to driverear shock absorber oil seal.
  • a. Nitrile Rubber (NBR) – this is the most commonly used material. It has good heat resistance properties and has good resistance to salt solutions, oils, hydraulic oils, and gasoline. Operating temperatures are recommended from -40 to 248⁰ F (-40 to 120 deg.C). Nitrile also functions well in a dry environment, but only for intermittent periods. The disadvantage of this material is poor chemical resistance.
