This QA1 right-hand jam nut kit contains six aluminum jam nuts with 3/4–16 threads, each sized with a 1-1/8-inch hex and 7/16-inch thickness for standard-thread applications. They act as locking nuts to secure mating fasteners and prevent rotation. QA1 offers these in steel or aluminum with standard and metric options and clear-anodized finish; the six-piece kit provides spare hardware for repairs.
