The QA1 jam nut is a single steel jam nut with right-hand 7/16-20 threads and an 11/16" hex, sized 1/4" wide. It provides a compact locking element for threaded linkages and adjusters where a durable steel option is preferred. QA1 also offers similar hardware in aluminum and in metric sizes, with clear-anodized finishes available on anodized aluminum versions.
