Ratchet Breaker Bar GEKO T00155 1/2" Drive 380 mm — for high-torque loosening

GEKO T00155 is a 380 mm break-over (breaker) bar with a 1/2" square drive engineered to provide high leverage for loosening tight, seized or rusted fasteners. The solid steel construction and straight bar profile deliver direct torque transfer from hand to socket, allowing controlled application of strong force when a standard ratchet cannot generate sufficient turning moment. Compatible with standard 1/2" sockets and manual tool sets, this breaker bar is intended for use where added leverage is required to free nuts and bolts in automotive, industrial and maintenance environments.

Advantages

The 380 mm length offers a balance between reach and torque multiplication, enabling higher turning force without excessive arm movement. The 1/2" square drive accepts common sockets for versatile use across many fastener sizes. A solid, single-piece bar design reduces flex under load and provides reliable, long-lasting performance in heavy-duty loosening operations. The simple, straight profile allows precise control of applied torque and easy positioning in confined or angled spaces when combined with extension pieces or universal joints.

Suitable for (tasks / use cases)

• Removing seized or rusted wheel nuts and hub bolts
• Loosening heavily torqued fasteners in automotive repair
• Industrial maintenance and machinery disassembly
• Construction sites where extra leverage is required

Key specifications

• Drive size: 1/2" square
• Overall length: 380 mm
• Design: straight break-over (breaker) bar
• Material: solid metal construction suitable for high-torque applications

How to use

Select a socket that matches the fastener size and fit it securely onto the 1/2" square drive. Position the socket over the nut or bolt head and align the breaker bar so force will be applied along the bar axis. Apply steady, controlled force to the free end of the bar—avoid sudden jolts—until the fastener begins to turn. For additional reach or angled access, use appropriate extensions or joints rated for high torque. After loosening, remove the breaker bar and continue with a ratchet or torque wrench as required.

Usage recommendations

Use appropriate personal protective equipment and ensure the socket and any extensions are correctly rated for high torque. Avoid using cheater pipes or modifying the bar; if extra leverage is repeatedly required, consider a longer breaker bar or mechanical assistance to prevent tool damage and ensure safety.
