Extension Bar 1/2" 127 mm YT-1247 YATO
Socket extension bar for a ratchet or torque wrench with a 1/2 inch drive. It allows work in places where standard sockets do not provide sufficient reach.
Features of the 1/2" socket extension bar
1/2 inch drive
A standard size used in vehicle and industrial workshops. Compatible with most ratchets, torque wrenches and sockets with this drive. It allows torques of up to 300 Nm to be transmitted, depending on the grade of the tool.
CrV 50BV30 chrome vanadium steel
A steel alloy enriched with chromium and vanadium, characterised by increased hardness and wear resistance. The 50BV30 designation specifies the exact chemical composition that provides mechanical strength while retaining elasticity.
127 mm working length
A dimension that provides an additional 127 mm of reach compared with a standard socket. Useful when working with components seated deep in mounting recesses or concealed by other parts.
Matt surface finish
A non-polished surface treatment increases corrosion resistance and makes everyday scratches less visible. The matt surface reduces glare when working at well-lit workstations.

Checking compatibility
Before buying, make sure that your ratchet or torque wrench has a 1/2 inch drive. This is verified by measuring the square section – it should be 12.7 mm. The extension bar works with all 1/2" sockets, regardless of manufacturer.
Use and maintenance
The extension bar should only be used with tools and sockets with a matching 1/2 inch drive. When working with a torque wrench, allow for the additional length of the extension bar, which may affect the accuracy of the torque measurement – in such cases the use of correction factors or calibration is recommended.
After use, clean the extension bar of dirt, dry it and protect it with a thin film of maintenance oil. Storing it in a dry place prevents corrosion. Regular checks of its condition include verifying that the ball bearing operates correctly and that there are no visible cracks or deformation.
