Impact socket accessory Proline 18927, 53 mm length

Proline 18927 impact socket accessory, 53 mm length, is a hexagonal impact socket engineered for use with impact wrenches and pneumatic or electric drive tools. Constructed from chromium-molybdenum (CrMo) steel, this socket is intended for heavy-duty fastening tasks in workshops, vehicle maintenance and industrial repair. The PRO-DRIVE internal profile reduces stress on bolt edges while enabling higher torque transfer and longer service life compared with standard chromium-vanadium sockets.

Advantages

The CrMo steel construction provides improved tensile strength and a higher yield point for longer durability under impact loads. A specially profiled rounded angle between the work planes — PRO-DRIVE system — mitigates excessive point loads on internal edges, reducing risk of socket wall failure and protecting bolt heads. The square drive is compatible with common locking mechanisms used on pneumatic tools, and the 53 mm length gives reach for recessed or hard-to-access fasteners.

Suitable for

• Heavy-duty fastening and loosening with impact wrenches
• Automotive repair and wheel, suspension or drivetrain service
• Industrial maintenance and equipment assembly
• Workshop use where extended reach is required

Key specifications

• Socket type: hexagonal impact socket
• Material: chromium-molybdenum (CrMo) steel
• Length: 53 mm
• Design feature: PRO-DRIVE rounded internal profile to reduce point loads
• Compatibility: square drive compatible with common pneumatic and impact tool locking mechanisms
• Intended use: impact applications with pneumatic or electric drive tools

How to use

Select the correct socket size for the fastener, attach the socket to a compatible impact wrench or adapter via the square drive, and ensure the locking mechanism is engaged. Apply controlled impact torque according to the tool and fastener specifications, avoiding excessive side loads. After use, inspect the socket for wear or damage, clean debris from the internal profile and store in a dry place to maintain performance.

Usage recommendations

Use the Proline impact socket with appropriate personal protective equipment and follow the impact tool manufacturer's torque and safety guidelines. Avoid using the socket on rounded or severely damaged fasteners and do not subject it to bending loads that exceed its design for axial impact torque.
