With our screw bits you don't give rust a chance.

SIHGAFIX® is made of hardened, stainless steel and is therefore the only way to exclude extraneous rust that occurs when screwing stainless steel screws. And thus also avoid expensive follow-up costs.

With SIHGAFIX® you'll get that screw out. And in!

SIHGA® screwdriver bits offer a wide range of advantages for timber construction:
  • specially developed for screwing into wood
  • extremely high strength values and service life thanks to vacuum ice hardening
  • precision-milled drive zone - ensuring a perfect fit
  • also available in high-alloy tool steel

Colour coding system and special sizes

Thanks to the practical SIHGAFIX® colour coding system, each bit size is immediately recognisable at first glance.

Frequently asked questions about the SIHGAFIX® bit system:

A bit (also called a screw bit) is a small, replaceable tool used in screwdrivers or screwdriving machines. It is used to insert or remove screws into or from wood, metal or other materials. The bit is made of hardened steel and is available in different shapes and sizes to accommodate different types of screws. There are bits for slotted, Phillips, Pozidrive, Torx and other screw heads.

The SIHGAFIX® bit system offers numerous advantages. Using the bits can increase efficiency in screwdriving work and reduce the risk of damage to screws and workpieces through better force transmission. The risk of injury from slipping on screw heads is also minimised. The screwdriver bits are compatible with various screwdriver handles and machines. By using the screw bits, this avoids the need to change screwdrivers and thus saves time and space. In addition, the bits are available in different sizes and shapes to meet the requirements of different screws and applications.

To take full advantage of a screwdriver bit, it is important to bear in mind that not all screwdriver bits are the same. There are significant differences, especially in steel core hardness and coating, which play an important role in the selection. To avoid rapid wear, you have to choose the right bit that is matched to the material being worked on, because enormous forces are exerted on the bit during screwing.
