Product details

Product description.

Rail vehicle fastening.

The product record identifies use across subways, light rail, EMUs and locomotives. Use the named component and its individual specification to locate the part within your vehicle assembly; a shared application category does not make different fasteners interchangeable.

Design basis

This is a drawing-defined or non-standard configuration. Start with the product name and catalogue reference, then provide the current drawing revision and the exact version required. The parameter table records the supplied specification; dimensions, material designation and acceptance requirements that are not stated there should be confirmed before quotation.

Drawing and part reference

Bore, diameter & height

Provide the bore diameter, outside diameter and overall height from the drawing, together with any end-face details and required fit. Keep short and long sleeve variants separate. A diameter-and-height designation should not be treated as a threaded fastener size, and a photograph should not be used to measure the part.

Configuration to confirm

Finish & assembly conditions

The listed treatment is Zinc-aluminium coating (FLZ) or custom finish. Specify which listed option is required, together with any drawing-defined preparation or inspection requirements. The recorded friction requirement should remain linked to that specification; it is not an installation-torque value. Tightening instructions and acceptance conditions need confirmation for the actual assembly.

Project-specific requirements

Selection guide.

A clear drawing and complete inquiry help distinguish the exact part from another fastener in the same application group.

Part reference
Send the drawing number and revision, or identify the existing component.
Dimensions
Bore, outside diameter and height. Mark any special geometry on the drawing.
Grade / hardness
Identify the required listed option and retain its original grade or hardness notation.
Surface requirements
State the required finish and any project-specific friction or inspection requirements.
Order scope
Specify quantity, additional components and your requested delivery date.
