The QA1 jam nut is a single steel jam nut with right-hand 1/2-20 threads and a 3/4" hex, measuring 5/16" wide. It serves as a compact locking component for heavier threaded adjusters and linkage connections where a larger hex and wider face are required. QA1 provides similar hardware in aluminum and metric options and notes anodized finishes for aluminum variants.
