Соединительная шпилька выпускного коллектора, M10 Caterpillar 4185121

A Exhaust Manifold Interference Stud is a threaded fastener with external threads on both ends and an unthreaded section in the middle. It features a slightly oversized thread on one end. This creates a tight, press-fit connection within a pre-tapped hole, eliminating the need for a nut and preventing loosening under even the most intense vibrations and shock loads.Attributes:• Resists loosening under heavy vibrations and loads• Made of Steel which has excellent strengthApplications:A Exhaust Manifold Interference Stud is used to fasten the outer manifold gasket with the manifold. It is a high-precision, vibration-resistant fastener for connections under extreme loads. During installation, the oversized thread is forced into the slightly undersized hole, compressing the surrounding material. This creates a frictional bond that prevents loosening due to vibration, ensuring a consistent and reliable connection. The pre-load generated also enhances fatigue strength.
