Fast Clips Railroad Fastening System

Railway Clip is used to fasten the rails to the underlying base plate together with the concrete sleeper. A variety of different types of heavy-duty clips are used to fasten the rails to the underlying baseplate or Sleeper, one common being the E Clip, which is shaped like a stubby paperclip. Another one is the SKL Tension Clamp, which is also the most widely used type all over the world. Others like KPO Clamp and Nabla Clip, also used in different situations.

Description

Technical Parameters

↵Rail fast Clip Fastening System

The Railway Fastclip is an innovative, single-component resilient fastening system that eliminates all threaded parts, relying instead on a precision-engineered interference fit between a spring steel clip and a cast iron or polymer shoulder embedded in the concrete sleeper. Its defining mechanism is a simple horizontal sliding action-the clip is driven laterally into a tapered pocket where its legs compress against internal shoulders, generating a pre-determined clamping force on the rail foot without any nuts, bolts, or torque wrenches.

Installation & Maintenance Perspective:

Parts Consolidation: Replaces threaded assemblies (bolt, washer, nut, clip) with a single active component, reducing warehouse SKUs and simplifying ordering.

Mixing Elimination: Without multiple part types, there is no risk of installing incorrect bolts or washers that could compromise clamping force.

Lightweight Packaging: The compact, uniform shape of Fastclips allows high-density packaging and efficient global shipping compared to bulky threaded fastener kits.

Maintenance & Operational Perspective

Visual Confirmation: Installers and inspectors can immediately verify correct clip position by sight-fully driven clips align with witness marks on the shoulder.
Tamper Evidence: Any clip that has worked loose or been disturbed is instantly obvious, as it will no longer sit flush against its seating reference points.
No Torque Ambiguity: Eliminates uncertainty about correct tightening-since there is no thread, there is no risk of under-torquing (loose fastening) or over-torquing (bolt failure).
