🔌 Function

Clamps a bracket or accessory to the engine structure, the flange head spreading the load across the mounting face.

⚠️ Common Signs of Failure

• Bracket or accessory found able to move on its mount
• A knock or rattle that changes with engine load
• Screw loose or backed out
• Flange face fretted or the mounting hole elongated
• Thread galled on removal

🛠️ 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
