A professional Tvardy 175 mm impact extension bar with a 3/4” drive, specifically designed for use with impact wrenches. Indispensable when a bolt or nut is located in hard-to-reach places—such as deep engine recesses, suspensions, or steel structures.
The socket is made from premium-grade chromium-molybdenum steel (CR-MO), a material specifically developed for impact tool applications.
| Feature | CR-MO Steel | CR-V Steel |
| Impact resistance | Very high – ideal for impact wrenches | Limited – for manual use only |
| Flexibility | Higher – absorbs vibrations | Lower – prone to cracking under impact |
| Hardness | Maintains hardness under load | Good, but lacks impact resistance |
| Recommended Use | Impact tools, industry, mechanics | Hand tools, hobbyist workshops |
In short – if you use an impact wrench, choose CR-MO. It withstands extreme forces and won’t let you down under tough conditions.
Durable construction – reliable even in the most demanding environments
Ball retention system – secure fit in the wrench socket
Precise fit – no play, efficient torque transfer
Anti-corrosion coating – resistant to rust and workshop greases
