Lock Nuts

Lock Nuts are designed to resist loosening from vibration or movement after installation.

FastPro Tip: Finish tightening Lock Nuts with a calibrated torque wrench to the manufacturer's or an engineer's specification to avoid damage, as impacts can easily over-tighten and strip threads or break components.
