Pan Head
|

Recommended for new designs to replace round, truss
and binding heads. Provides a low large diameter head,
but with characteristically high outer edge along the
outer periphery of the head where driving action is most
effective for high tightening torque. |
|
Round Head

countersinking is not practicable. Use where the
appearance is desirable. |
|
Square Head

|
The square head has a flat top surface, four flat
