The Wera 30 Piece Bit-Check Screwdriver Bit and Holder Set is a comprehensive screwdriver bit set designed for professional tradespeople working across a wide range of metal applications, providing 29 bits and a universal holder in a compact, organised case. The Bit-Check case is designed for practical on-site use, giving an at-a-glance overview of available bits so nothing gets misplaced mid-job. The multi-component case can be positioned upright for secure, stable bit storage on the workbench, and is compact enough to carry in a shirt pocket. Bits not in use are simply reinserted into their designated slots, keeping the set complete and ready for work. The included 899/4/1 universal bit holder features a strong permanent magnet and a stainless sleeve, accepting all ¼" hexagon head bits. It is compatible with power screwdrivers and can also be used in the chuck of an electric drill, offering genuine versatility across different tools and tasks. The set covers the most commonly used drive types in metalwork and general trade use, including Phillips, Pozidriv, TORX®, slotted, and hex (Allen) profiles. Wera's Hex-Plus geometry on hex bits reduces wear to socket head screws, helping fasteners last longer over repeated use.
