Rail Fastening Systems - DOGSCREW
They are more cost efficient and are easier and safer to install than the traditional dog spike. Unlike dog spikes, DOGSCREWTM can cope with tight-radius turns and high axle loads whilst still holding the gauge.
This performance is courtesy of a specially-designed flange, which transfers clamp force to the rail web or sleeper plate and a unique thread profile that pulls the timber hard up underneath the rail or plate.
The holding ability of DOGSCREWTM has been tested on some of Australia's toughest rail locations, and has easily out-performed other rail fastening techniques.
This has led to product approvals from major rail infrastructure companies such as Queensland Rail, Westnet / John Holland and Rail Infrastructure Corporation (NSW).
