⚙️ Key Features

• Confirmed within the TAD722VE engine-system parts range
• Integral flange distributes clamp load without a separate loose washer
• Thread, length and head geometry match the assigned position
• Suitable for engine heat and vibration exposure
• Use the specified tightening torque and sequence
• Exact schematic location must be confirmed before ordering
• Quantity varies by assembly, most commonly one

🔌 Function

Provides the specified clamping load at the assigned TAD722VE mounting point.

⚠️ Common Signs of Failure

• Threads are stripped or stretched
• The flange or drive head is damaged
• The joint repeatedly loosens
• The screw is bent or corroded
• Replacement is required where secure reuse cannot be confirmed

🛠️ 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
