Impact extension bar 3/4" 250mm CR-MO

Description

Impact Extension Bar 3/4" 250 mm CR-MO A professional Tvardy 250 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. Key Product Features: Tool type: Impact extension bar Total length: 250 mm Drive / socket size: 3/4" Material: CR-MO (chromium-molybdenum steel) CR-MO Steel – Why It’s Better Than CR-V? 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. Why Choose Tvardy Sockets? 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 Applications: Work with impact wrenches: pneumatic, electric, cordless Automotive workshops, vehicle mechanics Assembly of steel structures and hard-to-reach components Machinery servicing, heavy industry, construction
