The Wera 8740 C HF Zyklop In-Hex Sockets with Holding Function can, via a unique design, hold the fasteners within the socket. Assembly or disassembly becomes easy where fasteners are recessed, in awkward spaces or where overhead work is necessary.

Wera’s Hex-Plus drive design allows up to 20% more torque to be transferred and prevents rounding out and fastener head damage. Made from chrome-molybdenum and incorporating off-point drive, these sockets are designed for intensive use. Sockets are also guaranteed for production use with non-impact power tools.

The sockets are colour coded dependent on the size for fast tool selection; part of the wider Wera size identification system.

The Wera 8740 C HF Screw Hold 1/2in Drive Socket has the following specification:

Size: 4mm.
Length: 140mm.
