Extension bar YATO YT-1244, chrome vanadium steel, length 330 mm, 1 pc

YATO YT-1244 is a single-piece extension bar made from chrome vanadium steel with a length of 330 mm. It is designed to extend the reach of sockets and ratchets, allowing access to fasteners located in deep, recessed or hard-to-reach areas. The solid construction ensures reliable torque transfer and improved work ergonomics for automotive, mechanical and general maintenance tasks.

Advantages

The one-piece design eliminates weak joints and reduces the risk of failure under load, while chrome vanadium steel provides strength and wear resistance. At 330 mm length the extension bar offers increased reach without sacrificing control, and the polished finish helps resist corrosion and allows smooth insertion and removal of sockets. Its precise dimensions ensure a secure connection to compatible drive tools and sockets.

Suitable for

• Automotive repair and engine bay work where bolts are recessed
• Mechanical assembly and disassembly in tight spaces
• Maintenance tasks on machinery and equipment with hard-to-reach fasteners
• Use with ratchets and impact drivers (compatible sizes)

Key specifications

• Material: chrome vanadium steel
• Length: 330 mm
• Construction: single-piece (solid)
• Finish: polished/chrome-plated surface for corrosion resistance
• Drive compatibility: standard square drive for use with matching sockets and ratchets

How to use

Select a socket that matches the fastener size and attach it securely to the extension bar. Insert the extension bar’s square drive into the ratchet or torque wrench, ensuring a positive engagement. Position the socket over the fastener and apply controlled torque via the ratchet or wrench. For removal, reverse the ratcheting direction and support the tool to maintain alignment. Inspect the extension bar regularly for wear or damage and replace if deformation or excessive wear is visible.

Usage recommendations

Use the extension bar only with sockets and drive tools of the matching square size. Avoid sudden impact loads beyond the tool’s rated capacity and do not use the extension as a lever or pry bar. Keep the bar clean and lightly lubricated at the contact points to maintain smooth operation and prevent corrosion. Store in a dry place and inspect before heavy-duty jobs to ensure safe performance.
