TVH Shoulder Hex Bolt – HW-1690

This shoulder hex bolt functions as a precision pivot pin with a clamping head, measuring about 0.55 inch long, 0.6 inch wide, and 1.4 inch tall, and weighing roughly 0.15 pounds. The shoulder design gives it a smooth, precisely sized bearing section that a component can pivot or rotate around, while the hex head end provides the clamping force to keep the assembly secured.

This bolt is manufactured under the shared MCFA family of designs, which is why it cross-fits UniCarriers, Nissan, Caterpillar, Mitsubishi, Hyster, and Yale lift trucks that were built on common joint-manufacturing platforms. Because the shoulder surface is a wear point, repeated pivoting action can eventually groove or wear it down, at which point the components riding on it will develop play; replacing the bolt at that stage restores the tight, controlled movement the pivot was designed for.
