Questions
What countersink angle do these need?
ISO 7046 and DIN 965 heads are 90°. The hole needs a 90° countersink deep enough for the head diameter dk, or the head will stand proud.
Phillips (H) or Pozidriv (Z)?
Both recess types are defined in ISO 7046. Phillips is the usual choice; Pozidriv cams out less under torque. Say which one in your enquiry.
Can you make a raised (oval) countersunk head?
Raised countersunk heads (ISO 7047 / DIN 966) can be made to drawing. Send the drawing or a sample.
