Prime-Line 9075313 Nylon Insert Lock Nuts, 5/16 In.-18, Grade 18-8 Stainless Steel (20 Pack)

The 5/16 inch-18 Nylon Insert Locknut is a game-changer for any application where vibration resistance is crucial.

Its internal nylon ring grips bolt threads better than a standard finished nut, ensuring maximum stability and security.

Plus, it can also be used as a secondary nut to enhance the locking mechanism, providing an added layer of protection against loosening.

The side with the nylon insert should face towards the tip of the bolt, not towards the surface being fastened.

With its coarse thread type and UNC-2B specification, this locknut meets the highest standards for durability and performance.

Don't settle for anything less - choose the 5/16 inch-18 Nylon Insert Locknut for your next project and experience the difference it can make.
