A 39-piece Wera Tool-Check set is not interchangeable with every other 39-piece Tool-Check set.<\/strong> The complete part number and contents answer whether it includes the profiles and sizes you need.<\/p>\n

The Tool-Check PLUS 1 page<\/a> identifies 05049055001. The Imperial 1 page<\/a> identifies 05049060001. Both list 39 pieces, including a small ratchet, bit-holding screwdriver, holder, adapter, bits and sockets. The Imperial page explicitly identifies imperial socket sizes and Square-Plus\/Robertson bits; the PLUS 1 contents include metric hex sizes and Pozidriv entries.<\/p>\n

The drive interface is not the working size<\/h2>\n

A 1\/4-inch drive or bit mounting describes the connection within the tool system. It does not mean every working socket is 1\/4-inch, or that the set’s hex bits are all imperial. Keep drive interface, fastener profile and working size in separate fields.<\/p>\n\n\n\n\n\n\n\n\n

Compare a short list of real requirements<\/h2>\n

Use the documented fastener requirements for the equipment you intend to maintain. Check those against the complete contents list rather than assuming a large total covers them. Duplicate bits and adapters can contribute to a set’s count without adding the missing working size.<\/p>\n

The manufacturer describes the cited sockets for non-impact use. A compact ratchet or familiar drive size does not establish suitability for an impact tool, a torque-critical job or live electrical work. This comparison gives no operating or repair procedure.<\/p>\n

Our preference would be to choose the set that matches the required profiles and sizes, then consider storage and portability. The common 39-piece headline is a poor shortcut for that decision.<\/p>\n
