Standard Direct Fixation Fasteners

Designed, developed, laboratory proven and field validated, these track fastener systems offer unique advantages to trackwork engineers and maintenance personnel.


The fastener designs are economical, easy to install and maintain, corrosion resistant, and quiet under load. They have an inherent design flexibility to meet a wide range of performance specifications.
