Impact Socket HEX 1/2" H17 CR-MO Tvardy
Professional impact socket with a HEX H17 hex recess, made from chrome-molybdenum (CR-MO) steel. Designed for use with pneumatic and electric impact wrenches in industrial conditions.
Technical features
CR-MO chrome-molybdenum steel
A material with enhanced resistance to impact loads. The addition of molybdenum (Mo) improves fatigue strength and flexibility, which prevents cracking under the repeated impacts of an impact wrench. Compared with CR-V (chrome-vanadium) steel, CR-MO absorbs impact energy more effectively and retains its strength properties under intensive use.
HEX H17 recess
A hexagonal internal profile measuring 17 mm, used for hex-head bolts and screws. Precision machining of the recess minimises play and ensures full contact with the bolt edges, which reduces the risk of rounding the head at high torque.
1/2" drive
A square drive measuring 12.7 mm (1/2 inch), compatible with pneumatic and electric impact wrenches and hand ratchets with this drive size. Fitted with a retaining pin hole and a spring ring to prevent the socket from falling off.
Anti-corrosion coating
A dark, phosphated or oxidised surface that protects against corrosion in a workshop environment. The coating extends tool life on contact with the oils, greases and moisture encountered during mechanical work.

Applications
- Removal and fitting of suspension bolts in automotive workshops
- Work on brake calipers and braking system components
- Assembly of steel structures with HEX connections
- Maintenance of industrial machinery with hex fasteners
- Automotive work on underbody components
- Fitting and removal of structural reinforcements
- Repair of heavy equipment with HEX fixings
- Assembly work in steel construction
How to check compatibility
Make sure the bolt has a 17 mm internal hex recess (H17). The socket fits impact wrenches and ratchets with a 1/2" drive. Do not use impact sockets with torque wrenches – they can affect the accuracy of the torque reading.
CR-MO vs CR-V – differences in impact applications
Chrome-molybdenum (CR-MO) and chrome-vanadium (CR-V) steels differ in their mechanical properties, which affects their suitability for impact tools:
| Parameter | CR-MO | CR-V |
| Impact resistance | Very high – absorbs impact energy | Limited – risk of micro-cracks |
| Flexibility | Higher – the material flexes without cracking | Lower – brittle fracture under overload |
| Fatigue strength | Retains its properties under repeated loads | Faster degradation under impact work |
| Typical use | Impact wrenches, industry, heavy mechanics | Hand tools, ratchets, hobby workshops |
In practice, this means that CR-V sockets used with impact wrenches may crack or deform after a few dozen work cycles, whereas CR-MO withstands hundreds of thousands of impacts without losing its properties.
Use and maintenance
To extend the service life of an impact socket, follow a few operating rules:
Before use: Check the condition of the HEX recess – there should be no signs of rounded edges. Make sure the socket is firmly seated on the tool's drive (use the retaining pin for extra security).
During use: Keep the socket axis perpendicular to the bolt surface – working at an angle increases wear and the risk of damaging the head. Do not exceed the maximum torque recommended by the impact wrench manufacturer.
After use: Clean the socket of dirt, swarf and grease. Store in a dry place, preferably in a tool organiser. Check the condition of the anti-corrosion coating periodically – protect it with maintenance oil if necessary.
