⚙️ Key Features

• OEM thread diameter, pitch and length
• Specified material and strength class
• Factory flange or head geometry
• Maintains the required clamp load
• Correct tightening torque is essential
• Quantity varies by assembly, most commonly three

🔌 Function

Applies and maintains the specified clamp load between the joined components.

⚠️ Common Signs of Failure

• Damaged internal hex or flange head
• Stretched or corroded threads
• Incorrect bolt length bottoming in the bore
• Oil, coolant or exhaust leakage from poor joint compression

🛠️ 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
