## ⚙️ Key Features

-   5.25 inches (133 mm) long
-   0.082 kg
-   Inlet and Exhaust System group
-   29 applications
-   133mm (Volvo assembly listing)

## 🔌 Function

Clamps a manifold, riser or exhaust component through a deep joint, with the length chosen so the thread engages fully.

## ⚠️ Common Signs of Failure

-   Exhaust or inlet leak at the joint the screw clamps
-   Screw seized in the casting by corrosion
-   Thread wasted or stripped over the exposed length
-   Head corners rounded from earlier removal
-   Screw snapped on removal, usually at the corroded section

## 🛠️ Service Notes

-   Screw 3853431 is the longer 6.25 inch (159 mm) version but is published lighter at 0.059 kg, so the weights do not track length here - order strictly by length
-   Long exhaust-side screws seize deep in the casting; heat and patience beat force, and a snapped screw turns a gasket job into a machining job
