The railway sector is characterized by a rising demand for reliability, speed and punctuality. To make trains faster and more economical, lightweight materials are used increasingly. In addition, short throughput times in production and lean maintenance of the trains and railway technology need to be ensured. This places some unique requirements on fasteners.
We understand these trends as well as the resulting challenges, and provide railway-specific fastening solutions that meet the highest safety and quality standards. In this way, we help our customers increase their efficiency and productivity.
Rail-specific Fasteners Sorted by Application in Rail Vehicle Construction
Supply Units in Rail Vehicles
In this application, the comfort of the passengers as well as a fast accessibility for maintenance and inspection of the equipment are paramount. The connecting elements must, above all, be quickly replaceable, captive, reusable for assembly and disassembly, and suitable for easy and safe mounting.
Fastening elements for railway supply units include:
Compression latches designed for quick and safe installations
Hose clamps - Heavy-duty clamps for the most demanding assemblies
High strength threaded inserts prevent rotation due to torsion or vibration, even at the highest tightening torques
In this central application, structural stability and reliability are essential to guarantee passenger safety. We therefore recommend fasteners that are easy to assemble and disassemble, made of high-strength materials, with a high corrosion resistance and compliance with the high safety standards.
Slotted self locking nuts - Locking function for various applications in the train
Lock bolts - Permanent and vibration resistant mechanical fastening
Grounding studs - Bolts to discharge leakage current
Tensioner nuts - Precise and economical mounting of large bolts and studs
Bogie in Rail Vehicles
The bogie plays a vital role in the train. Its main requirements are operating reliability, maintainability and traveling comfort through sufficient suspension and damping. Fasteners must, above all, be vibration-proof, corrosion resistant, resistant to extreme temperature changes, and able to maintain clamp force of assembly.
Lock washers - Securing through friction and mechanical locking
Wedge-locking fasteners - Self-locking through tension
Hex head locking screws - Multifunctional screws with serrated flange
Tension control bolts - Cost-efficient installation of high strength pre-loaded bolts
Interior of Railcar Vehicles
Inside the train, the emphasis is on traveling comfort as well as safety for the passenger. Luggage racks, grab poles, seats and folding tables must also withstand daily stress. To satisfy these demands, we offer fasteners which can be used in various materials, are available in different color variations and meet high design and functionality needs as well as requirements for light construction.
Fastening elements for the train interior include:
Long-lasting hinges for easy positioning of folding tables
Fasteners for composite materials - Reliable mounting in soft and composite materials
Threaded inserts - Lightweight inserts with high pull-out strength
Fasteners for C-rails for stable yet flexible mounting
High strength blind rivets - Strong solution for structural assembly
Cable tie plates - Space-saving organization of wire bundles
Pan head screws with flange - Multifunctional screws with integrated washer in flange
Notched screws - Special screws to prevent manipulation
Energy Supply of Railcar Vehicles
Fasteners in this application must meet the highest safety demands. In addition to the security of the connection itself, fire protection is a key element here. Thus, the main requirements on the fastening solutions are corrosion and vibration resistance as well as fire protection.
Fastening elements for the energy supply system in railway technology include:
