Impact Socket Accessory Proline ZR18941, Length 57 mm

Proline impact socket accessory ZR18941, length 57 mm, is designed for heavy-duty fastening tasks with impact wrenches. Constructed from chromium-molybdenum (CrMo) steel, this impact socket delivers increased tensile strength and improved yield performance compared with standard chromium-vanadium alternatives. The 57 mm length provides reach for recessed fasteners while maintaining compatibility with common impact tools and locking mechanisms used in workshops and industrial environments.

Advantages

The CrMo construction offers enhanced durability and resistance to deformation under high torque. PRO-DRIVE rounded internal angles reduce stress concentrations on both the socket and fastener, allowing for higher torque transfer without premature wear or chipping of bolt heads. The square drive interface is compatible with standard locking systems on pneumatic and electric impact wrenches, ensuring a secure connection during repeated high-torque cycles. The overall design balances strength and accessibility for routine maintenance and repair work.

Suitable for

• Automotive repair and wheel fastening where high torque and reach are required
• Industrial maintenance tasks with pneumatic or electric impact wrenches
• Workshops performing heavy-duty fastening and disassembly of machinery
• Situations requiring reduced damage to bolt heads due to the PRO-DRIVE profile

Key specifications

• Type: hexagonal impact socket accessory
• Material: chromium-molybdenum (CrMo) steel
• Length: 57 mm
• Drive interface: square drive compatible with standard locking mechanisms
• Design feature: rounded internal angles (PRO-DRIVE) to reduce point loads
• Intended use: heavy-duty, high-torque applications

How to use

Select the correct socket size for the fastener and attach the socket to a compatible impact wrench using the square drive and locking mechanism. Ensure the socket is seated fully on the fastener before applying torque. Operate the impact wrench following the tool manufacturer’s safety instructions and recommended torque settings to avoid over-torquing. After use, inspect the socket for wear or deformation and store it in a dry place to prevent corrosion.

Usage recommendations

Use with impact-rated extension bars or adapters when additional reach is needed, and avoid using the socket on hand-only tools not designed for impact service. Regularly check for rounded edges or cracking; replace the socket if significant wear appears to maintain safe and reliable performance.
