Prime-Line 9075294 Nylon Insert Lock Nuts, 5/16 In.-18, Grade 2 Zinc Plated Steel (100 Pack)

The "Internal Nylon Ring Bolt" is a game-changer for any application where vibration resistance is crucial.

Its unique design features an internal nylon ring that grips bolt threads better than a standard finished nut, providing unparalleled stability and security.

This innovative product can also be used as a secondary nut to enhance the locking mechanism of the main nut, ensuring a tighter and more secure fastening.

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 bolt is built to last and can handle even the most demanding applications.

Don't settle for anything less - choose the "Internal Nylon Ring Bolt" for your next project and experience the difference for yourself.
