Impact Socket Accessory Proline ZR18427, 43 mm Length

Proline ZR18427 is an impact socket accessory with a 43 mm overall length designed for use with impact wrenches and pneumatic or electric impact drivers. It functions as a short adapter or extension element, enabling secure connection between a drive tool and hexagonal sockets for fastening and loosening bolts and nuts. Constructed from chromium-molybdenum (CrMo) steel and featuring a square drive compatible with common locking mechanisms, this accessory is intended for professional and DIY tasks that require a compact, high-strength connector under changeable loads.

Advantages

The Proline impact socket accessory is manufactured from CrMo steel, which provides higher tensile strength and improved yield characteristics compared with standard chromium-vanadium alloys. It incorporates the PRO-DRIVE design with rounded internal angles to reduce concentrated point loads on socket edges, enabling increased torque transfer while reducing the risk of wall failure and protecting bolt heads. Its short 43 mm length ensures better access in confined spaces and lower lever forces, while the square drive fits most pneumatic device locking mechanisms for reliable use with impact drivers and wrenches.

Suitable for

• Fastening and loosening bolts and nuts in automotive maintenance
• Assembly and disassembly tasks in mechanical workshops
• Construction and installation jobs requiring compact impact accessories
• DIY repairs where a short, robust adapter is needed for impact tools

Key specifications

• Overall length: 43 mm
• Drive type: square drive compatible with common locking mechanisms
• Material: chromium-molybdenum (CrMo) steel
• Design feature: PRO-DRIVE rounded internal angles to reduce point loads
• Intended use: for pneumatic and electric impact drivers and wrenches
• Form factor: short impact socket accessory/adapter

How to use

Select the appropriate socket and attach it to the Proline impact accessory by aligning the square drive and engaging the locking mechanism of your impact tool. Mount the accessory onto a compatible pneumatic or electric impact driver or wrench, ensuring the connection is secure before applying torque. Use the accessory for tightening or loosening hexagonal fasteners; due to its short length, it is particularly useful in confined spaces and for operations that require direct torque transfer with reduced leverage.

Usage recommendations

Wear appropriate personal protective equipment and follow the impact tool manufacturer's torque and safety guidelines. Inspect the accessory for wear, cracks, or deformation before use and replace it if damage is detected. Use sockets and accessories rated for impact service only; avoid using this CrMo accessory with non-impact hand ratchets. Store in a dry environment to prevent corrosion and keep the drive connection clean to ensure proper locking.
