Pan Head Self-Tapping Screws (DIN 7981) – 304 (A2) Stainless Steel
Our 304 (A2) stainless steel pan head self-tapping screws are manufactured to DIN 7981 / GB 845. The rounded pan head spreads the clamping load, and the cross recess (Phillips) drive plus sharp point make them fast and reliable to drive into thin sheet metal, plastics and wood without a pilot hole.

Frequently Asked Questions
What are pan head self-tapping screws used for?
The domed pan head provides a wide bearing surface that spreads the clamping load on thin materials without tearing through. Combined with a self-tapping thread that cuts its own hole in sheet metal or plastic, they are the go-to general-purpose fastening screw.
Can these screws be used without a pilot hole?
Yes — in thin sheet metal, plastics and soft wood the sharp point and thread-forming profile drive directly without pre-drilling. For harder or thicker substrates, a small pilot hole is recommended.
What is the difference between DIN 7981 and DIN 7982?
Both are self-tapping screws: DIN 7981 has a pan (dome) head that sits on the surface; DIN 7982 has a countersunk flat head that finishes flush with the surface. Choose by whether you want the head visible or flush.
Do you provide material certificates?
Yes. Material test certificates per EN 10204 3.1 are available on request, and our manufacturing is ISO 9001:2015 certified. RoHS and REACH compliance documentation can also be provided.
