Wera 8740 A HF Zyklop 1/4" Drive Long Hexagon Socket Bit Metric

This 4mm x 100mm variant of the Wera 8740 A HF Zyklop bit socket combines compact hexagon sizing with extended reach, making it indispensable for precision work on smaller socket head fasteners in deep-set locations. The 100mm length provides exceptional access to recessed screws in electronics, instruments, and precision machinery where space constraints demand specialised tooling. The 4mm hexagon size targets fine-pitch fasteners commonly found in precision equipment, optical assemblies, and delicate mechanical systems. Despite the compact size, the holding function maintains secure screw retention throughout positioning and installation—crucial when working with small fasteners that are easily lost. Hex-Plus technology protects these smaller fasteners from rounding, whilst the knurled section enables precise manual control during alignment.
