Pollution

Stainless steel is inherently rust-resistant. However, if ordinary steel tools are used for screwdriving in stainless steel, abrasion can cause the tool to shed steel particles that adhere to the material and can lead to rust formation. Besides the aesthetic impact of this "contamination," as this phenomenon is known, it can also have negative consequences for the structure itself, potentially resulting in significant repair costs. Using stainless steel tools prevents this contamination caused by abrasion.

Stainless steel tips

Using stainless steel tips prevents rust from forming on stainless steel screws or surfaces. Contamination on stainless steel primarily results from abrasion when tightening screws with conventional steel tools. Abrasion produces strongly adherent steel particles that, under the effect of oxygen, turn into rust.
