🔌 Function

Clamps an EGR, inlet-manifold or fuel-system component to its mating face, holding the joint gas- or fuel-tight.

⚠️ Common Signs of Failure

• A hiss or soot mark at the joint the screw clamps
• Component found loose against its face
• Screw seized or the head corroded thin by exhaust gas
• Thread found galled or the screw snapped on removal
• Flange face distorted by heat

🛠️ Service Notes

• The integral flange spreads the load and forms the bearing face, so do not add a separate washer unless the workshop manual for your engine specifically calls for one
• Clean the threads and the seating face before fitting — grit, paint or old sealant under the flange gives a false torque reading and the joint will slacken off in service
• Where the flange is serrated it must bear directly on clean metal to grip; discard any screw with a deformed flange or damaged serrations rather than reusing it
• Tighten to the torque and sequence given in the workshop manual for your engine, and treat the screw as single-use where the manual specifies an angle-tightened or stretch fastener
• Check the thread in the receiving component at the same time; a pulled or corroded thread will not hold a new screw however carefully it is torqued
