Impact socket accessory Proline ZR18943, length 57 mm

Proline ZR18943 is a 57 mm impact socket accessory engineered for use with impact wrenches and other pneumatic or electric impact tools. Manufactured from chromium-molybdenum (CrMo) steel, this hexagonal socket is intended for fastening and loosening nuts and bolts in demanding working conditions such as automotive repair, industrial maintenance and construction. The socket’s design includes rounded internal angles and the PRO-DRIVE system to reduce point loading on bolt heads and extend service life.

Advantages

The CrMo steel construction delivers higher tensile strength and an increased yield point compared with standard chromium-vanadium sockets, resulting in improved durability under repeated impact loads. The PRO-DRIVE rounded internal angles mitigate concentrated stresses on both the socket and the fastener, enabling higher torque transfer while reducing the risk of chipping or deformation. The square drive fits common locking mechanisms on pneumatic devices, ensuring reliable engagement during heavy-duty use.

Suitable for

• Automotive repair and wheel nut removal
• Industrial equipment maintenance and assembly
• Construction site fastening and disassembly tasks
• Use with pneumatic and electric impact wrenches

Key specifications

• Type: hexagonal impact socket
• Material: chromium-molybdenum (CrMo) steel
• Length: 57 mm
• Drive style: square drive compatible with standard impact tool locking mechanisms
• Design feature: PRO-DRIVE rounded internal angles to reduce point loading
• Intended use: impact-rated fastening and loosening of nuts and bolts

How to use

Select the socket size that matches the fastener, attach the socket securely to the square drive of the impact wrench or adapter, and engage the tool according to the manufacturer’s instructions. Apply controlled impact torque and reverse direction when loosening. After use, inspect the socket for wear or deformation, clean off debris, and store it in a dry place to prevent corrosion.

Usage recommendations

Use the Proline 57 mm impact socket only with impact-rated tools and accessories. Avoid using damaged or significantly worn sockets; replace them if cracks, rounding, or severe deformation appear. For optimal performance, pair the socket with the correct drive adapter and use appropriate torque settings for the specific fastener and application.
