Hex head self-tapping screw 4.8x13 DIN7504K ZN

You can drive the hex head with a socket or a socket bit in a drill or impact driver. This gives a firm grip, even when you fit many screws in a row. The screw drills its own hole, so pre-drilling is usually not needed for thin material.

What do you use a hex head self-drilling screw 4,8x13 for?

This type of screw is used to fasten sheet material, profiles and thin metal parts to each other or to a substrate. The short length of 13 mm suits applications where the total material thickness is limited. Always check that the parts to be joined together are not thicker than what the drill point can handle.

What does the code DIN7504K ZSK SW8 ZN mean?

DIN 7504 is the standard for self-drilling screws. The letter K refers to the shape of the head, ZSK stands for hex and SW8 for a width across flats of 8 mm. ZN indicates that the screw has a zinc coating. This coating offers basic protection against rust, especially when used indoors or in places that stay dry.

What should you look for when choosing?

Consider the thickness of the material, the substrate and the environment in which the screw will be used. For outdoor work or damp spaces, a stainless steel version may be a better choice than a galvanised screw. Use a socket or socket bit that fits SW8 exactly, so the head is not damaged and the screw is held securely.
