Screwdrivers, bits and hex keys

Choose the screwdriver, bit or hex key according to the fastener profile and access to it. Establish the exact size and tool shape before comparing handles, lengths or complete sets.

The profile is the first selection criterion

Record the fastener's designation and size. The names include different profiles, including slotted, PH, PZ and TX designations. Match the exact tool to the specific fastener instead of choosing solely by a similar tip shape. Check the selected reference's intended use in the documentation. If preparing a set for several tasks, list the profiles and sizes required; the total part count does not show whether every required variant is present.

Screwdriver or interchangeable bit

For a standalone screwdriver, check the working length, overall dimensions and access to the fastener. For a bit, compare the holder connection and intended use. Clarify whether you are buying an individual working part, holder, handle or set. The general system name does not prove that all supplementary parts are included. For a hex key, compare the exact profile and size and check the shape needed to reach the installation position.

Dimensions for the actual location

Distinguish the profile size from the tool's length and other dimensions. With restricted access, check the space required for the head, holder and handle movement. A similar overall length does not mean an identical application. If the task requires a particular technical version, confirm it for the exact model. Handle colour and a general catalogue description do not replace the manufacturer's data for the corresponding reference.

Review the supply format too. A set may be described with different included tools, adapters and accessories; check every required element. When adding to an existing system, keep the holder or handle code beside the chosen working parts. Establish compatibility for the specific combination without assuming it from a shared brand or similar name.

Assemble according to the tasks

The products shown from WERA and KNIPEX can be compared by reference after this selection. For nuts and a different drive format, browse spanners, ratchets and sockets. For another specific operation, check specialist hand tools. The general tools and measuring section connects the equipment. Finally, check profiles, sizes, drive and included parts instead of choosing a kit solely by the number of products.
