This is a left-hand threaded inner cap nut for stud-piloted (Budd) dual wheel systems on heavy-duty trucks and trailers.
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 threads onto the wheel stud and provides a squared body that the outer lug nut tightens against to secure steel or aluminum rims. Replace it whenever threads are damaged, corroded, or after any wheel-end service that requires disassembly.
