This 22-piece Wiha hex L-key set and 8-piece Wiha screwdriver set bundle is ideal for precise fastening and unfastening of hex socket and slotted/Phillips screw applications. The hex key set includes hardened steel ball-end keys in metric sizes 1.5-10mm and inch sizes 1/16-3/8in to grip screw heads securely without slipping. Larger key sizes from 3-10mm use Wiha's MagicRing technology with a hardened spring steel ring to hold fastener heads hands-free for positioning during assembly/disassembly. Keys are organized in a ProStar holder for portability. The screwdriver set has chrome-vanadium-molybdenum steel blades with precisely machined tips for durability and exact fastener fit. Rotating caps on the ergonomic plastic handles allow fingertip spin control. Slotted and Phillips tips in sizes 1.0-4.0mm and #000-#1 cover precision applications. An included canvas pouch keeps the set organized. With hex keys for grip and hands-free operation plus precisely machined screwdriver tips, this bundled fastening tool kit complements your needs for detail-oriented assembly and repair tasks.
