3/4" 330 mm Impact Extension Bar YT-1163 YATO
An impact extension bar is an essential tool in any professional mechanical or automotive workshop. The YT-1163 combines a 330 mm length with a robust 3/4 inch square drive, allowing work with impact wrenches in hard-to-reach places.
Features of the 3/4" impact extension bar
3/4 inch square drive
The 3/4" (19 mm) size is the standard for professional air and electric power tools. The square shape of the drive ensures even distribution of torque, eliminating the risk of the socket slipping when working under heavy loads. The extension bar is compatible with impact wrenches rated up to 1500 Nm.
Chrome-molybdenum CrMo steel
CrMo material is characterised by increased resistance to impact and torsion. The chromium content increases surface hardness, while molybdenum improves the internal structure of the steel. Hardening ensures durability under intensive impact use, typical of automotive and industrial workshops.
330 mm working length
The 330 mm length provides access to fasteners in deep recesses of engines, gearboxes and the suspension of commercial vehicles. This length retains sufficient rigidity, minimising flex while transmitting torque. It performs well when working on the wheels of vans and lorries.
Impact-rated construction
A reinforced internal structure designed for use with air and electric impact tools. The hardened surface of the female socket and the drive shank prevents deformation during repeated cycles of dynamic loading. The extension bar transmits the full power of the impact wrench without any risk of damage to the mechanism.

Tool compatibility
The extension bar is compatible with air and electric impact wrenches fitted with a 3/4" drive. Before purchase, check the drive size of your tool and the required torque – for a 3/4" drive the typical range is 200–1500 Nm. The extension bar requires the use of impact sockets with a 3/4" female drive.
Use and maintenance
Before each use, check the condition of the square drive and the socket – scratches, chipping or deformation are unacceptable. The impact extension bar should be pushed fully into the tool's socket, checking that the connection is secure.
After use, it is advisable to clean the extension bar of contamination and to lightly oil the working surfaces. Storing it in a dry place prevents corrosion. Do not use the extension bar as a lever or subject it to side impacts – such use leads to permanent deformation.
When working in chemically aggressive environments (paint shops, industrial plants), more frequent cleaning and anti-corrosion treatment are advisable.
