DIN 7981 refers to pan head tapping screws, known for their rounded top surface and flat bearing surface, ideal for high-torque applications in sheet metal.
Which materials are best for corrosion resistance?
For maximum corrosion resistance, especially in marine or chemical environments, we recommend using 316 Stainless Steel (316SS). 304SS is excellent for general outdoor use.
What size range is available for these screws?
We supply a comprehensive size range from ST2.9 up to ST6.3 to accommodate various industrial requirements.
Are these screws compliant with international standards?
Yes, our pan head tapping screws are manufactured to meet DIN, ISO, JIS, and AISI standards to ensure global compatibility.
Can I use these screws in carbon steel applications?
Absolutely. We offer these screws in carbon steel material, which is often chosen for its high strength and cost-effectiveness in non-corrosive environments.
What is the difference between 304SS and 316SS materials?
While both are stainless steels, 316SS contains molybdenum, which provides superior resistance to chlorides and salt spray compared to 304SS.
