Con Rod Spanner

An important accessory to accompany Hornby’s growing collection of TT:120 scale steam locomotives, the Con Rod Spanner is essential for maintenance and ensuring reliable running. Buy now from the Key Model World Shop for £4.99.

The small size of TT:120 scale locomotives means that screw-threaded bolts that hold connecting rods and valve gear onto the wheels of steam locomotives are very fine and require this specially designed Con Rod Spanner to safely tighten or unscrew the bolts.

An ideal tool for repairing or carrying out routine maintenance on Hornby’s highly detailed range of TT:120 scale steam locomotives and class 08 diesel shunter, the TT8038 Con Rod Spanner engages with the important bolts mounted on locomotive wheels.

Featuring a turned metal handle, the spanner is comfortable to handle and easy to use. A vital tool for every beginner or established railway modeller in TT:120 model scale. 

Product highlights include:

• Turned metal handle


• User-friendly accessory


• Designed for Hornby TT:120 steam and connecting rod-fitted diesel locomotives
