Type: Impact socket
Size: 21 mm
Length: Short
Drive: 1/2” square drive
Material: High-quality CR-MO (chromium-molybdenum) steel
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.
Premium durability – resists cracking, deformation, and wear
Precision fit – minimizes risk of slippage and bolt damage
Safety pin hole – compatible with locking pin systems
