Wera 8790 HMC HF Zyklop 1/2" Drive Lock on Hexagon Socket Metric 1/2" 17mm

About this tool

The Wera 8790 HMC HF Zyklop 17mm socket with 1/2" drive is one of the most widely used sizes in automotive and heavy engineering work, appearing frequently on wheel nuts, cylinder heads, and structural bolts. The 1/2" drive is ideally matched to the higher torque demands of 17mm fasteners, while the holding function keeps bolts firmly on the socket during approach — a real advantage in overhead or confined working conditions. Chrome vanadium steel construction with a matt chrome-plated finish ensures durability and resistance to wear. Wera's colour-coded Take it Easy Tool Finder system makes this socket instantly identifiable in a full set, and the knurled lower end and ball stop groove provide a secure, positive drive connection. Features and Benefits: • Non-impact socket suitable for manual or power tool operations • Holding function secures screws on the tool, reducing the risk of dropping fasteners • Take it Easy Tool Finder: colour coding by size for rapid identification • Chrome vanadium steel with matt chrome-plated finish • Ball stop groove and knurled lower end for a secure, confident grip Contents: 8790 HMC HF Zyklop socket with 1/2" drive with holding function, 17 x 37 mm Specifications: Socket Size: 17mm Drive Size: 1/2" Length: 37mm
