Impact socket accessory Proline ZR18412, length 39 mm

Proline ZR18412 is an impact socket accessory with a length of 39 mm designed for use with impact wrenches and pneumatic or electric power tools. Manufactured for heavy-duty applications, this Proline socket adapts drive sizes and connects standard sockets to fastening tools for loosening and tightening bolts and nuts in automotive, industrial and maintenance environments. The accessory is made from chromium-molybdenum (CrMo) steel for improved durability and is compatible with common square drive locking mechanisms.

Advantages

The 39 mm Proline impact socket accessory is constructed from CrMo steel, providing higher tensile strength and improved yield properties compared with ordinary chromium-vanadium sockets. Its geometry includes specially profiled rounded open angles (PRO-DRIVE system) that reduce concentrated point loads on internal edges, allowing higher torque transfer while protecting bolt heads and extending socket life. The square drive fits most locking mechanisms used on pneumatic tools and impact wrenches, making the accessory suitable for demanding and variable load conditions.

Suitable for

• Automotive repair and maintenance tasks involving wheel nuts and fasteners
• Industrial assembly and disassembly where impact torque is required
• Maintenance and service work with pneumatic or electric impact wrenches
• Workshops and tool cabinets requiring durable socket extensions or adapters

Key specifications

• Type: impact socket accessory / adapter
• Length: 39 mm
• Material: chromium-molybdenum (CrMo) steel
• Drive interface: square socket compatible with standard locking mechanisms
• Design feature: rounded internal angles (PRO-DRIVE system) to reduce point loads
• Intended use: heavy-duty impact applications with pneumatic or electric tools

How to use

Select the appropriate Proline ZR18412 impact accessory for the intended socket size and attach it to the impact wrench’s square drive until the locking mechanism engages. Mount the matching socket onto the accessory, ensure a secure fit, and operate the impact tool according to the tool manufacturer’s torque and speed recommendations. After use, inspect the contact surfaces for wear, clean debris from the drive interfaces, and store the accessory in a dry place.

Usage recommendations

Use the Proline impact accessory only with tools rated for impact operation. Match socket sizes correctly to avoid rounding fastener heads, and apply torque settings suitable for the fastener and material. Periodically inspect for cracks, deformation or excessive wear, and replace the accessory if damage is found.
