Impact socket accessory Proline ZR18950, 72 mm length

Proline ZR18950 impact socket accessory, 72 mm length, is designed for use with impact wrenches and pneumatic or electric impact drivers. Made for demanding workshop and automotive tasks, this hexagonal impact socket provides a direct connection between tool and fastener while meeting the higher strength and durability requirements of impact-rated applications. Its elongated shape and durable material construction make it suitable for recessed fasteners and repetitive heavy-duty use.

Advantages

This socket is manufactured from chromium-molybdenum (CrMo) steel, offering higher tensile strength and improved yield point compared with conventional chromium-vanadium socket materials. The PRO-DRIVE internal profiling reduces concentrated point loads on bolt edges and socket corners, enabling higher torque transfer and extending service life. The square drive interface is compatible with common locking mechanisms used on pneumatic devices, and the 72 mm length provides extra reach for recessed or hard-to-access fasteners.

Suitable for

• Automotive maintenance and repair where impact-rated tools are required
• Workshop and garage fastener removal and installation
• Industrial assembly and maintenance tasks with pneumatic or electric impact drivers
• Applications requiring extended reach for recessed bolts and nuts

Key specifications

• Type: hexagonal impact socket, elongated/standard-length profile
• Length: 72 mm
• Material: chromium-molybdenum (CrMo) steel
• Internal profiling: PRO-DRIVE rounded work plane angles to reduce point loads
• Drive interface: square drive compatible with common pneumatic locking mechanisms
• Intended use: impact-rated applications with pneumatic or electric impact wrenches/drivers

How to use

Select the socket size that matches the fastener head, attach the socket securely to the square drive of the impact wrench or driver, and ensure any retaining ring or locking pin is correctly engaged. Position the socket squarely on the fastener, apply steady, controlled impact force, and avoid side loads. After use, inspect the socket for wear or deformation and clean off contaminants before storage. Use appropriate personal protective equipment and follow the tool manufacturer's safety instructions.

Usage recommendations

For optimal performance, use this Proline impact socket with impact-rated tools only, and avoid using it with hand ratchets or non-impact drivers. Store the socket in a dry place and periodically check for cracks or rounded internal corners; replace if any damage is detected to maintain safe torque transfer and prevent fastener damage.
