Fabco Nut 688-0274 or 6880274 is a 1-14 hex thin-height light nut used on Fabco transfer case, PTO, and steerable drive axle assemblies. The 1-14 thread callout indicates a 1-inch major diameter with 14 threads per inch, and the thin-height, light profile keeps the fastener low where clearance is tight. Small hardware like this is easy to overlook on a rebuild but is critical to holding a joint at the correct torque. This is a genuine Fabco part sold by Pro Gear and Transmission.
