MAKITA B-40163 1/2" Impact Socket 19x38 mm

MAKITA B-40163 Impact Socket 1/2 Inch, Size 19x38 mm.
The MAKITA B-40163 is a standard metric short impact socket with a 19 mm opening and a 1/2-inch (12.7 mm) square drive. The 19 mm size is one of the most widely used sizes in automotive and general maintenance work.This socket is made from Chrome-Molybdenum Steel (Cr-Mo), a material superior to standard steel due to its exceptional toughness and resistance to impacts from an impact wrench, ensuring the socket will not crack or deform under high torque and impact conditions. Impact sockets feature thicker walls than standard Chrome-Vanadium (Cr-V) sockets for enhanced strength.With an overall length of 38 mm (Short Type), the B-40163 socket offers high application versatility, particularly for tightening/loosening fasteners where compactness is needed. The socket is coated with a Black Phosphate Finish, a coating that helps reduce rust and increases wear resistance during continuous use.

Specifications
- Strength for Impact: Made from premium-grade Cr-Mo steel, engineered to withstand repeated impacts and immense torque from impact tools.
- Reliable Fastener Grip: The 6-point design provides full surface contact, delivering efficient torque transfer and reducing damage to fastener heads.
- Corrosion Resistance: Black phosphate finish helps prevent rust and corrosion from harsh operating environments.
- Compact and Maneuverable: The 38 mm length allows convenient operation in tight, hard-to-reach areas.
- Ready for Impact Wrenches: The drive end is designed to support the use of a pin and O-ring for secure and safe attachment to the tool.

Applications & Usage
- Tire Replacement and Maintenance: The 19 mm size is the standard size used for removing/installing most automotive lug nuts.
- General Automotive Maintenance: Used for tightening/loosening 19 mm fasteners in high-torque components such as engines, suspensions, and brake systems.
- Industrial Applications: Suitable for structural work, machinery installation, and bolting applications requiring speed and high torque in combination with a 1/2-inch impact wrench.
