DIN 7504 Pan Head Self-Drilling Screws (Forms N & M)
We supply DIN 7504 pan head self-drilling screws in form N (cross recess) and form M (cross recess, A2 stainless), from 2.9mm to 6.3mm diameter. The hardened drill point cuts its own hole in sheet steel and taps the thread in one operation - no pre-drilling needed within the point's drilling capacity.
Also known as: self drilling screw pan head, din 7504 n, din 7504 m, tek screw pan head, drill point screw, self driller pan.

Materials & strength
Drill point
The fluted drill point cuts its own pilot hole in sheet steel, then the thread taps in behind it - a one-operation fixing.
Forms N and M
Both forms carry a cross recess pan head, available in steel zinc plated, steel black and A2 stainless.
Stainless steel A2
A2 stainless for corrosion resistance across the range.
Steel finishes
Zinc plated and black finishes on hardened carbon steel.
Related specificationsWhat is the difference between a self-drilling and a self-tapping screw?
A self-tapping screw (such as DIN 7981) forms its own thread but needs a pre-drilled or punched hole; a self-drilling screw has a drill point that cuts the hole itself, then taps the thread in the same operation.
What do form N and form M mean?
They are the DIN 7504 form designations for the cross recess pan head pattern. These screws are available in steel zinc plated, steel black and A2 stainless.
How thick a steel section can these drill?
Drilling capacity depends on the point length fitted to each diameter, so it varies across the range. Send us your requirement with the section thickness and we will match the right size and point.
Are these available in stainless steel?
Yes - A2 stainless is listed across the 2.9mm to 6.3mm range.
