Impact socket accessory Proline ZR18419, 39 mm length

Proline impact socket accessory ZR18419, 39 mm length is a hexagonal impact socket designed for use with impact drivers and wrenches. Manufactured from chromium-molybdenum (CrMo) steel, this accessory is intended for heavy-duty fastening and loosening operations in automotive, industrial maintenance and mechanical repair environments. The 39 mm length and the hex profile provide a balance between access to fasteners and resistance to torsional load, while the square drive interface is compatible with common locking mechanisms on pneumatic and electric impact tools.

Advantages

The CrMo steel construction offers increased tensile strength and a higher yield point compared with standard chromium-vanadium sockets, contributing to longer service life under variable loads. The socket incorporates the PRO-DRIVE system with specially profiled rounded open angles between work planes, which reduces point loads at the internal edges and helps prevent chipping or deformation. The design allows transmission of increased torque without premature wall failure and protects bolt head edges. The square drive is compatible with most locking mechanisms used in pneumatic devices, enabling secure connection during operation.

Suitable for

• Automotive repair and tyre/workshop operations
• Industrial maintenance and equipment servicing
• Mechanical assembly and heavy-duty fastening tasks

Key specifications

• Socket type: hexagonal impact socket
• Material: chromium-molybdenum (CrMo) steel
• Length: 39 mm
• Drive interface: square drive compatible with common locking mechanisms
• Design feature: PRO-DRIVE rounded open angles to reduce internal edge loading
• Intended use: heavy-duty fastening and loosening with impact tools

How to use

Fit the socket onto the matching square drive of the impact driver or wrench, ensuring the locking mechanism secures the socket before applying torque. Use appropriate torque and impact settings for the fastener and application to avoid overloading tool or fastener. When removing seized or corroded fasteners, apply steady impact force and avoid excessive side loads that could compromise the socket or fastener head. Inspect the socket regularly for signs of wear, cracking or deformation and replace it if damage is detected.

Usage recommendations

Store the socket in a dry place and keep it mounted or packaged to prevent mechanical damage. Use appropriate personal protective equipment when operating impact tools and select the correct socket size and drive to match fasteners. Do not use a cracked or excessively worn socket; replace to maintain safe operation.
