Product features
Extraneous rust
Stainless steel has the property of not rusting. However, if tools made out of conventional steel are used for stainless steel components or screws, the particles left behind from these tools can adhere to the surface and then rust. This effect – known as extraneous rust – can impair the visual appearance and even cause structural damage that may result in expensive repair work. The wear particles that cause this rust effect can be prevented by using stainless steel tools.
Screw stainless steel together with stainless steel!
Stainless Steel Bits
Wera stainless steel bits are manufactured out of stainless steel so unsightly rust can be avoided. The stainless steel bits from Wera are vacuum ice-hardened and have the hardness and strength needed for screw connections. There are no limitations to the industrial applications they are suitable for.
Vacuum ice-hardened

Hex-Plus
Hexagon socket screws are a problem, because the contact surfaces that transfer the force of the tool to the screw are very narrow. The consequence: the head of the screw can be damaged, usually rounding out the recess. Hex-Plus tools have larger contact surfaces to prevent this, driving from the flats of the recess, rather than the corners. Good to know: Hex-Plus tools fit into every standard hexagon socket screw!

Product description
High quality bits out of stainless steel for hexagon socket screws. Wera stainless are made out of stainless steel which prevents the formation of unsightly extraneous rust. The Hex-Plus profile offers a greater contact surface in the head of the screw. The notching effect is therefore reduced to a minimum and damage to the screw head more or less eliminated. ¼" hexagon, suitable for holders as per DIN ISO 1173-F 6.3.
