Confirm the part fits before you buy. Applications and interchange numbers are researched and audited per part.
We don't publish fitment for this part yet. Rather than guess, get it confirmed against your truck in under a minute.
It is placed under a bolt head or nut to spread the clamping load, prevent surface damage, and help maintain tension in bolted joints. On heavy trucks and trailers, this size is commonly used on leaf spring u‑bolts, shock mounts, frame brackets, and hitch hardware. Replace whenever a washer shows flattening, cracking, or heavy corrosion that could reduce its ability to distribute load.
