Screw Spikes for Railway Turnouts | Custom Turnout Spikes Supplier
Introduction

We specialize in manufacturing full range of railway turnout components, including the screw spike for railway turnouts. It serves to deliver preload force, for fastening the steel rail via pressure plates or elastic clips and preserving rail stability. Railway turnout works under complex stress and sustains repeated alternating impact and vibration loads. For this reason, the screw spike for railway turnouts is designed with a larger diameter for higher performance compared with ordinary track screw spikes.
As a professional manufacturer of railway fasteners, we supply high performance rail screw spikes for railway turnout lines. Our turnout screw spikes are fabricated from ordinary carbon steel or high‑quality carbon steel. Available steel grades: Q235B, 35#, 35K, 45#, 40Cr. We supply various anti‑corrosion treatments including Dacromet, hot‑dip galvanizing and sherardizing. Customization is available per customer specific requirements. Below are our railway screw spikes for concrete or wooden switch sleeper, 50kg/m or 60kg/m rail turnout, supplied to our European clients. Please refer to the drawing and technical requirements below for details.
