Impact socket Proline 18490, 1/2" drive

Proline 18490 is an impact socket with a 1/2" drive designed for heavy-duty fastening and loosening with impact wrenches, pneumatic or electric impulse tools. Manufactured for use in automotive repair, industrial maintenance and construction, this impact-rated socket set delivers reliable performance where high torque and durability are required. The set includes multiple metric sizes with a work length of 39 mm for the 1/2" range and is supplied in a metal box for secure storage and transport.

Advantages

The impact socket is made from impact-grade alloy steel and heat-treated to resist deformation and cracking under repeated high-torque use. Its 1/2" drive interface provides secure engagement with impact tools while the recessed geometry and consistent wall thickness allow even torque transfer. The metal storage box protects sockets from corrosion and keeps the set organized for quick selection on the job.

Suitable for

• Automotive repair and wheel nut removal/tightening
• Industrial machinery maintenance and assembly
• Construction and on-site mechanical fastening tasks
• Workshops and professional service technicians using impact tools

Key specifications

• Drive size: 1/2"
• Included socket sizes (metric): 10, 12, 13, 14, 15, 16, 17, 18, 19, 22
• Working length (for 1/2" sizes): 39 mm
• Material: impact-grade alloy steel (heat-treated)
• Finish: corrosion-resistant coating
• Storage: metal box included

How to use

Select the socket size that matches the nut or bolt head, align the socket onto the 1/2" drive of the impact wrench, and secure it with the tool's retainer or pin if applicable. Operate the impact wrench according to the tool manufacturer's instructions, applying measured bursts of torque to avoid over-tightening. After use, clean debris from the sockets, inspect for wear or cracking, and return them to the metal box to prevent loss and corrosion.

Usage recommendations

Use impact-rated sockets only with impact tools; do not use them with hand rachets or breaker bars designed for hand torque to avoid injury or damage. Wear appropriate eye and hand protection when operating impact wrenches and periodically inspect sockets for deformation or hairline fractures. Store the sockets in the supplied metal box in a dry environment to maintain service life.
