Description

This is a 9/16-18 stainless steel jam nut (USS & SAE) from HILLMAN, designed for use where a secondary nut is needed to lock a primary nut in place. A jam nut is useful when you want to secure an adjustable fitting or prevent a threaded connection from working loose under vibration or periodic adjustment. The stainless steel finish provides a durable, low-maintenance surface for general fastening tasks. Use these jam nuts on bolts and threaded rods when installing machinery components, adjusting gate hardware, or locking down fixtures that may require occasional retightening. Their 9/16-18 thread size is compatible with standard fasteners of that specification, making them a straightforward choice when a compact, locking nut solution is required.
