Rail Fastening Systems - Extended Sleeper Life

DOGSCREWTM extends sleeper life in a number of ways.

  • Fibre splitting and bending prevalent at the steel/timber interface is minimized courtesy of the special thread profile. This reduces the opportunity for moisture to rot the sleeper
  • Water penetration is prevented because the round screw shank totally seals the hole
  • Timber splitting during insertion is reduced because the lateral forces generated can be up to three times less than those caused by hammering dog spikes or lock spikes into the sleeper
  • Damage to the bottom of the sleeper is eliminated because there is no need for the hole to be drilled right through the timber.
