Featuring a precise 4 mm hex tip and a generous 140 mm overall length, this tool delivers extended reach where shorter wrenches struggle, helping you access recessed fasteners without constant repositioning.

•

• 
  Reach: 140 mm length provides long-lever access to fasteners tucked into crowded assemblies.
• 
  Profile: Slim, straight shaft clears surrounding components, wires, and brackets for quicker, smoother turns.
• 
  Practical versatility: An everyday essential for bike maintenance, DIY furniture builds, and light machinery tweaks—wherever a 4 mm hex is needed.
• 
  Reliability in practice: A straightforward tool that helps you apply steady torque with minimal effort, reducing fatigue during longer repair sessions.

Why choose this long-reach 4 mm hex wrench? When space is at a premium, a standard short key forces you to stop, reposition, and restart. The 140 mm length of the Hex Wrench-4mm-L-140mm removes that friction, letting you work more efficiently on projects where bolt heads sit deep or behind components. It’s an ideal companion for bike enthusiasts tuning derailleurs or brakes, DIYers assembling modular furniture, and technicians performing routine hardware checks in compact machines.

Usage tip: align the 4 mm hex tip squarely with the bolt head, apply steady pressure, and turn with controlled torque. The long, precise tip helps you maintain engagement and reduces the chance of slipping, so you can get the job done right the first time.
