Unique-Bargains 4mm Extra Long Arm T-Handle Hex Key Wrench Chrome Finish

SKU CH-B1HG-EJTZ6

A 4 mm hex key with a T-handle, dual-length shafts of 315 mm and 13 mm, and a chrome-plated steel shaft for extra reach and torque

  • Extra reach for deep fasteners with 360 mm long arm
  • Greater torque leverage from 315 mm ball-end shaft
  • Dual hex ends of different lengths clear obstructions
  • Firm T-handle grip adds turning power for tough jobs
  • Heat-treated steel with chrome finish resists wear and corrosion

4 mm T-Handle Hex Key for Deep Access

This 4 mm hex key wrench is built from heat-treated 70# steel with a polished chrome finish. The T-handle grip delivers firm control and extra turning leverage for stubborn fasteners. It suits DIY makers, automotive technicians and household maintenance tasks.

Long Dual-End Shafts Clear Obstructions

The tool offers two usable ends: a 315 mm ball-end shaft for deep reach and a 13 mm hex-end shaft for tight clearances. Both ends share the same 4 mm drive size, letting you switch between reach and compact access without changing tools. Overall length is 360 mm by 89 mm.

Replaces Standard Short Allen Keys

This wrench upgrades from fixed L-shaped keys that lack reach and torque. The jump is worth it when fasteners sit deep inside engine bays, machinery frames or assembled furniture. It is not for jobs requiring multiple hex sizes or powered driving.

Questions about this item

How much torque can the 4mm hex ends handle before rounding off?

The 70# steel shaft with heat-treated construction and chrome finish resists rounding under high torque, while the 360mm total length and T-handle design multiply your applied force for stubborn fasteners.

Does the T-handle stay comfortable and cool during all-day use?

The orange plastic T-handle gives a firm grip that does not conduct heat, and the 70g weight keeps wrist fatigue low even when you are turning bolts for hours.

What else do I need to use this wrench on a 4mm fastener?

Nothing else — the tool has a 4mm hex end on both the 315mm ball-end shaft and the 13mm short shaft, so it fits the fastener directly out of the package.
