418-5121: M10 Exhaust Manifold Interference Stud

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 strength

Applications:
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.

• Material: Alloy Zinc,Carbon Steel
