How to select the right countersink for a flat-head screw?
Match the countersink angle to the screw head angle — 82° is standard for inch flat-head screws. Ensure the body diameter is larger than the screw head. For hard materials like stainless steel, choose carbide (as with this APPROVED VENDOR model) for longer tool life and cleaner cuts.
