Rivet Seat – 1/2″

The A. Stucki Rivet Seat is a cupped, heavy-duty metal washer seat designed for use in the installation of running boards on rail cars. Its shallow, dish-shaped profile distributes clamping load evenly around the rivet, providing a secure, stable seat that helps prevent loosening under the vibration and dynamic forces common in railroad applications.


Available in a 1/2″ size to ensure proper fit and performance during running board installation.
