Features
:
Professional Impact Sockets : Engineered to withstand high torque tools like pneumatic or electric impact wrenches.
Durable Cr‑Mo Steel : Made from hardened Chrome Molybdenum – tougher and more shock-resistant than Cr‑V.
Precise 6‑Point Design : Grips flat sides of fasteners, reducing rounding and slippage.
Wide Metric Range : Covers key sizes from 10 mm to 32 mm — ideal for automotive, machinery, and industrial tasks.
Secure Metal Case : Keeps tools organized and protected, with size-marked slots for each socket.
Laser-Etched Markings : Easy-to-read size indicators for fast identification and efficiency.
Use this 1/2″ impact socket set with compatible impact wrenches or drivers for high-torque applications such as automotive repair, tire changes, or heavy machinery maintenance.
Select the correct socket size between 10 mm and 32 mm to match the fastener and ensure a secure fit to avoid stripping or rounding.
Attach the socket firmly to the impact tool’s drive until it locks in place.
Ensure your impact tool is set to the appropriate direction for tightening or loosening, and maintain a steady grip during operation.
Avoid prolonged high-speed use on small fasteners to prevent breakage or overtightening.
After use, remove the socket from the tool and return it to the metal case for safekeeping and easy access.
Maintenance Guidance :
Clean sockets with a dry or lightly oiled cloth after each use to remove dirt, grease, and debris.
Store the sockets in the provided metal case to protect them from moisture, dust, and impact damage.
Apply a light coating of oil periodically to prevent rust, especially if the set is stored in a humid environment.
Avoid using sockets on tools that exceed their rated torque to prevent cracking or deformation.
Inspect sockets regularly for wear or damage, especially around the drive end and contact points, and replace if necessary.
