Hexagon flat jam nuts

The flat side of the Hexagon flat jam nuts are flush with the bearing or linear guide rail, allowing the adjustment device to be easily locked in the correct position. They won't protrude to prevent moving parts from being hooked. You can use them to fix lead screws or belt tensioners.

Product details and parameters

Hexagon flat jam nuts can be used to lock the main nuts on threaded rods, adjust the tension of belts or chains, or fix mechanical bearings. They can also fix shaky bicycle seats or stabilize camera tripods.

In the factory, machines keep running and vibrating, and these Hexagon flat jam nuts hold the parts together. They are used to fix the components on the conveyor belt to ensure that all components remain in place during high-speed operation. In auto repair shops, they are also used for engines. When mechanics assemble engine parts, Hexagon flat jam nuts can ensure that nuts and bolts do not loosen due to engine vibration.

Professional tip: If Hexagon flat jam nuts often slip, please degrease the threads first. If you are worried about rusting, please choose stainless steel anti-loosening nuts. Do not reuse deformed anti-loosening nuts.

Installation Tips

When installing Hexagon flat jam nuts, you need a common nut and bolt that have been tightened to the required extent. Then, remove the nut. Just like installing other nuts, put it on the bolt and cover it above the ordinary nut. Make sure the threads are aligned. After installation, pick up the wrench and rotate it clockwise. Tighten the anti-loosening nut until it is tightly attached to the ordinary nut.
