Everything in Self-tapping sheet metal screws

Choosing and using a self-drilling screw with a hex head

A DIN7504K self-drilling screw 4.8x50 is a zinc-plated screw with a hex head for fastening thin sheet material. The screw has a hex head with a key size of 8 (SW8) and a dimension of 4.8 mm thick and 50 mm long. The drill point drills and taps in a single operation, so pre-drilling is usually not necessary.

Read more

These screws are widely used in construction, installation and metalworking, for example when mounting steel profiles, sheet metal or roof cladding. On this page you will find the version in zinc-plated steel (ZN). Always check that the size and material suit your application.

What do DIN7504K, SW8 and ZN mean?

DIN7504 is the standard for self-drilling screws with a drill point, and the letter K refers to the version with a hexagonal head. SW8 stands for key width 8: you drive the screw in with a socket or socket bit of 8 mm in your cordless drill. ZN means the screw has a zinc coating that prevents rust. That is sufficient for dry, indoor applications. For damp or outdoor situations with higher requirements, another finish or stainless steel is better.

What should you watch out for with size 4.8x50?

The 4.8 mm is the thread diameter and the 50 mm is the total length. Choose a length at which the drill point and part of the thread pass fully through the underlying material. A screw that is too short does not grip properly, one that is too long protrudes unnecessarily. Also check the thickness of the material you want to drill through: self-drilling screws are intended for thin sheet material and not for thick, solid structural parts.

Tips for use

Use a screwdriver with adjustable speed and a well-fitting socket so the head does not get damaged. Place the screw straight on the workpiece and maintain even pressure. Do not overtighten, as the thread can strip in thin material. Preferably work with a screw that suits the hardness of the material you are fastening.

Frequently asked questions

Do I need to pre-drill with a self-drilling screw?

Usually not. The drill point drills the hole itself and forms the thread at the same time, provided the material is not too thick.

Is this screw suitable for outdoor use?

The zinc coating provides basic protection against rust. For heavy outdoor use or a damp environment, a heavier finish or stainless steel is the wiser choice.

Which socket do I need for this screw?

A socket or nut driver with a key size of 8 (SW8), suitable for the hex head.
