Profile: Wera Tools (UK) Ltd. manufactures screwdriving tools. We also provide ratchets, stainless steell tools, nut setter, holders, bit sets, impact drivers & protective hammers and torque tools. If conventional steel tools are used on stainless steel elements or stainless steel screws the wear debris of these tools can adhere to the surface and begin to rust. This effect, known as extraneous rust, can impair the visual impact and even cause structural damage, resulting in high costs for the necessary repair work. Wear debris that causes extraneous rust can be prevented through the use of stainless steel tools. Our foam inserts fit into the common tool cabinets and work benches.
