Flange Nut – M10 Nyloc is an M10 x 1.5 nylon-insert flange nut used on the exhaust system, securing the joints between the turbocharger or manifold, the front pipe or catalyst, and the intermediate pipe.

The nylon insert locks the nut against vibration, and the integral flange spreads the clamping load across the exhaust flange. The number required varies by joint.
