Product Overview
Product Application
DIN 968 Phillips pan head self-tapping screws with a flange—often referred to as “self-tapping screws with washers” or “washer-head self-tapping screws”—feature an integrated flange beneath the pan head.
This design increases the load-bearing surface area and protects the surface of the connected parts without the need for a separate washer.
The thread dimensions, thread profile, and tolerances of DIN 968 fully comply with the specifications of DIN 7970 or the latest international standard, DIN EN ISO 1478.

Product Advantages
Boosts Efficiency
Pre-assembled washer saves time on automated assembly lines.
Resists Loosening
Large contact area provides high vibration resistance.
Common Questions
Do DIN 968 screws require pre-drilling?
It depends on the application.
- For plastics and some soft materials, pre-drilling may not be necessary.
- For sheet metal and harder materials, a pilot hole is typically recommended to ensure proper thread formation and prevent material damage.
The pilot hole size should match the screw diameter and material thickness.
Can DIN 968 screws replace bolts and nuts?
Not always.
DIN 968 self-tapping screws are ideal when access is available from only one side of the assembly and when creating threads directly in the base material. For heavy structural connections requiring higher preload and load capacity, bolts and nuts are generally preferred.
Are DIN 968 screws suitable for outdoor use?
SUS304 for general outdoor use, SUS316 for coastal and high-corrosion environments.
What is the difference between DIN 968 and DIN 7981
DIN 968 provides a larger bearing surface and improved load distribution due to its integrated collar.
