General Features

  • Standard system supplied as a solid bolt with a dynamic device, polyethylene tube, resin mixing device, slot pin nut and dome ball attached.
  • The energy absorption ability of the Dynamic Solid Bolt is achieved by attaching a treated dynamic device to the bolt. When the seismic event occurs the solid bolt is able to be pulled through the dynamic device hence enabling the bolt to absorb the energy and remain intact. The polyethylene sleeve acts as a debonding agent that allows the solid bolt to slip through the dynamic device.
  • The dynamic device is mechanical therefore enabling repeatability in regard to the energy absorption process.
  • The Dynamic Solid Bolt is manufactured under strict QC procedures.

Supply & Packaging

  • 50 bolts per pack
  • Packed using appropriate timbers and steel strapping
