Product Description

Main uses
1. Fixed with rail fasteners
It is used to connect the rails with fasteners (such as spring bars, rail plates) to ensure that the rails are stably fixed on the sleepers or track plates.
It is applicable to various track structures such as ballasted track, ballastless track and turnout sections.
2. Provide adjustable fastening force
The tightening force of the T-bolt can be adjusted through the nut to adapt to different rail types (such as 60kg/m, 50kg/m) and the requirements of track working conditions.
3. Anti-vibration and anti-loosening
Anti-loosening nuts or double-nut designs are adopted to prevent bolts from loosening due to vibrations during train operation.
4. Applicable to special tracks
It can be used in various scenarios such as high-speed railways, heavy-haul railways, subways, and industrial railways, and is suitable for environments with high and low temperatures and high humidity.

 

Typical usage scenarios
High-speed railway ballastless track
It is used to fix the fastener system of high-speed railways (such as WJ-7 and WJ-8 type fasteners) to ensure the smoothness of the track.
Case: China's CRTS III ballastless Track System.
2. Heavy-haul railway
To withstand the impact of large-axle load trains, T-bolts need to have high strength and fatigue resistance.
Case studies: Heavy-haul lines such as the Daqin Railway and Shuohuang Railway.
3. Metro and Urban Rail Transit
Fastener systems used in subway tunnels or elevated sections reduce vibration transmission and lower noise.
Case: Metro DT2 type fasteners, elastic strip III type fasteners.
4. Turnouts and crossing lines
The force-bearing area of the turnout is complex. T-bolts need to ensure the precise position of the rail to prevent displacement.
5. Industrial Railway
In damp, corrosive or high-temperature environments, stainless steel or galvanized T-bolts are used to enhance durability

 

T-shaped head design: Embedded in the sleeper or fastener groove to prevent the bolt from rotating and facilitate installation.
High-strength materials: Commonly used are 8.8 grade and 10.9 grade alloy steels, and stainless steel is used in some environments.
Anti-loosening measures:
Double nuts + spring washers
Nylon lock nut (anti-loosening nut)
Thread adhesive (Loctite)

 

T-bolts are key components of railway track fastener systems, suitable for high-speed rail, heavy haul, subways and industrial railways, etc. They ensure the long-term stability of the track through high-strength and anti-loosening designs. Correct selection and installation are the keys to ensuring its performance.
