This shoulder bolt secures critical mechanical assemblies on Bartell ride-on trowels, providing the precise shank diameter and thread engagement needed to maintain tight tolerances in high-vibration concrete finishing environments. Bartell engineers these machines to the tightest tolerances in the industry, and fasteners like this 1/2" shoulder by 3/8-16 threaded bolt are essential to maintaining that precision, a worn, stripped, or incorrect bolt can introduce unwanted play into pivot points, linkages, or gearbox-adjacent components, compromising the responsive steering and blade performance the TITAN series is known for.

The shoulder bolt's unthreaded 1/2" shank acts as a precision bearing surface, allowing controlled rotation or articulation at the joint it occupies, while the 3/8-16 thread locks it firmly in place. At 1-1/4" in length, it is sized specifically for the assembly clearances found on TITAN-series ride-on trowels. When inspecting your machine for wear, check shoulder bolts any time you notice looseness in steering linkages, irregular blade pitch response, or abnormal vibration, these are common indicators of fastener wear in high-cycle applications. Always replace with the correct OEM specification to preserve fit and function.

Compatible with the following Bartell Global ride-on trowel models:
