Impact socket accessory Proline ZR18919, 50 mm length

Proline impact socket accessory ZR18919, 50 mm length is an impact-rated hexagonal socket designed for use with impact wrenches and pneumatic tools. The 50 mm reach provides additional access to recessed fasteners and replacements for worn or missing impact drive components. Manufactured from chromium-molybdenum (CrMo) steel and finished to work under variable loads, this accessory is intended for professional and DIY applications where an impact-capable socket is required.

Advantages

The CrMo steel construction offers higher tensile strength and improved yield point compared with standard chromium-vanadium sockets, resulting in extended service life. The Pro-Drive internal profile features rounded open angles between work planes to reduce peak stresses on internal edges, enabling increased torque transfer while protecting both the socket walls and bolt heads. The square drive end is compatible with common locking mechanisms used on pneumatic impact tools. The product is supplied in protective retail packaging, either a cardboard box or on a hanger.

Suitable for

• Accessing and turning recessed hexagonal fasteners in automotive and mechanical repair
• Use with pneumatic impact wrenches and electric impact drivers
• Replacement or spare part for impact socket sets in workshops and on-site service

Key specifications

• Type: hexagonal impact socket accessory
• Length: 50 mm reach
• Material: chromium-molybdenum (CrMo) steel
• Drive end: square drive compatible with pneumatic tool locking mechanisms
• Internal profile: Pro-Drive rounded angles to reduce stress on fastener edges

How to use

Select the correct socket size that fits the hexagonal fastener and attach the socket securely to the impact wrench or driver’s square drive, ensuring any retaining pin or ring is engaged where applicable. Position the socket over the fastener and operate the impact tool at the recommended speed and torque settings for the fastener and application. After use, inspect the socket for wear or deformation and store it in suitable tool storage to prevent damage.

Usage recommendations

Use the socket only with impact-rated tools and accessories; do not use it with hand ratchets or cheater bars. Regularly inspect for cracks, excessive rounding, or wear before each use and replace the socket when damage is found. For optimal performance, match the socket size precisely to the fastener and use appropriate torque settings for the material and fastener grade.
