Using a stainless steel bit eliminates the potential for any extraneous rust

When tightening stainless steel screws without
using stainless steel tools, abrasion can result
which can lead to extraneous rust and pitting
in the screw which puts security at risk.

WITTE Stainless Bits are ”ice-hardened“ for excellent
durability in professional use. The weatherproof
and noncorrosive material permits the
use in outdoor construction, solar technology,
marine and food industries as well as other
sensitive areas of application.
