Screw/dowel combination NG

Small dowel, huge effect

Screw dowel combination NG product brochure
  • Significantly lower pre-stressing loss & plastic deformation
  • Maintenance-free for lower LCC
  • Increased lifetime of the sleeper

Optimized thread geometry

  • Innovative internal thread geometry
  • External thread functionally segmented into two areas
  • Lower torque during tightening
  • Precise screw guidance
Upper dowel area

While tightening the screw, almost no tangential and therefore no lateral forces arise

Lower area

Only marginal tangential forces arise

More special features
