Jergens & Acme
Spinner-GripTM Flange Lock Nuts are the latest innovation in locking nuts. Free Spinning installation eliminates the need to "wrench" the nut down the thread.
Grade 8 strength and quality, but will work with any grade of fastener.
Does not damage threads or plating on fasteners.
Locks to the part - not to the threads. (Exceptional performance in applications with heavy vibration)
Greater temperature range than nylon insert locknuts.
Hardness of 28 - 38 HRc - More effective at maintaining clamp load under vibration.
Not limited to 5 reuses, as with most other torque lock nuts.
