Countersunk screws have a conical head that sits flush with the surface, for a clean-looking fixing on machinery and visible components.

How to choose the right part: you need the thread diameter (from 3 to 8mm) and the length (from 8 to 50mm) — both figures must match the original screw, or the seat/hole it fits into.

Material: stainless steel, resistant to corrosion and frequent washing, suitable for food environments.

Head type: slotted (flat screwdriver), for simple fixing with common tools.

For other fasteners go back to Hardware or Nuts.

Frequently asked questions

How do I measure the countersunk screw I need to replace?
Measure the thread diameter and overall length with a caliper: both figures are needed for the correct part.

Why a countersunk head instead of a normal head?
It sits flush with the surface, avoiding protrusions that could interfere with other moving parts or be hazardous to the touch.
