Product Details
QA1 is known for making performance suspension and driveline components. This steel jam nut is a small but important piece for certain engine builds or adjustments. It features left-hand threads with a 1/4-28 size, meaning it tightens in the opposite direction of most standard fasteners.
This particular jam nut is made from steel for solid durability. It has a 7/16 inch hex size, which is a common size for many wrenches, and is 5/32 inch wide. While it's a simple part, having the correct jam nut is essential for securing components and preventing them from loosening under vibration or stress.
