In addition, Spinner-Grip nuts lock to the base part, not the bolt threads, providing “better tensile strength to hold the entire fastener assembly (bolt, part and nut), making them particularly effective in high-vibration applications,” Jergens added.
They are said to be well suited for material-handling equipment, medical equipment, vibratory applications, and hard-to-reach fastening areas. The all-stainless steel locking nut is also ideal for environments in which wide variances in temperatures and harsh environmental conditions are likely, according to the manufacturer.
Spinner-Grips do not require the use of flat washers (except in slotted applications) and will replace standard nuts as well as all types of lock nuts. They can be re-used several times, “not limited to five or fewer re-uses like nylon insert lock nuts,” Jergens concluded.
