Product overviewOverview
Tooth direction matters. A pan head with a flange gives a rounded, low-profile head with a defined bearing area, and the adhesive seals that area as the screw is driven. The pan form avoids the sharp edge of a countersunk head on thin or coated panels, where a countersink would break the coating.
installed by torque wrench with teeth facing the clamped part.
Key featuresFeatures
- Pan head avoids cutting a countersink into a coated panel.
- Unidirectional and bidirectional tooth patterns for different load directions.
- Large flange area lowers bearing stress on thin panels.
- Can be combined with a thread patch for locking at both the thread and the bearing face.
Typical applicationsApplications
- Wind turbine and tower fittings
- Industrial pumps and compressors
- Automotive chassis and suspension
Selection notesSelection
Unidirectional teeth must face the load direction; reversing them cancels most of the locking effect.
Frequently asked questionsFAQ
Why choose a pan head over a countersunk head here?
A countersunk head needs a matching cone in the panel, which cuts through coating and leaves a raw edge. A pan head with a flange bears on the surface and keeps the coating intact.
What matters during installation of the Integrated Pan Head Flange Screw with Pre-applied Adhesive?
Seat the teeth against the clamped part and tighten to the specified torque. Pan head avoids cutting a countersink into a coated panel.

Manufacturing and inspection
Tooth angle, height and distribution are checked optically.We recommend a pilot assembly at the actual torque and mating part before locking the process parameters for volume.
