🔌 Function

Clamps a joint with an integral flanged head that spreads the load over the mating face without a separate washer.

⚠️ Common Signs of Failure

• Joint working loose, weeping or fretting at the flange face
• Thread stripped, stretched or pulled
• Flange face under the head bruised, dished or corroded
• Head drive recess rounded out

🛠️ Service Notes

• Clean the mating face and the threaded hole before refitting — trapped debris under a flanged head gives a false torque reading and the joint loosens off afterwards
