Impact socket accessory Proline ZR18520, 38 mm length

Proline ZR18520 impact socket accessory, 38 mm length, is an impact-rated hexagonal socket designed for use with compatible impact wrenches and drivers. Manufactured from forged chromium-vanadium steel and subjected to a controlled hardening and tempering process, this socket meets demanding durability expectations for heavy fastening tasks. The chrome-plated and polished surface provides corrosion resistance and smooth operation, while the PRO-DRIVE edge profiling reduces point loads on fasteners and extends the life of both the socket and screw heads.

Advantages

The 38 mm Proline impact socket offers enhanced strength for repetitive impact applications and complies with DIN 3124 and PN-ISO 1711 durability standards. Its chromium-vanadium construction and heat treatment provide consistent hardness and resistance to deformation under high torque. The chrome finish improves resistance to rust and simplifies cleaning after use. The PRO-DRIVE profiling reduces wear on fasteners and distributes load more evenly across contact surfaces.

Suitable for

• Automotive repair and wheel fastening
• Industrial assembly and maintenance with impact wrenches
• Heavy-duty fastening where impact-rated sockets are required
• Workshops and service stations performing repetitive torque applications

Key specifications

• Socket shape: hexagonal (standard and extended hexagonal profile)
• Material: forged chromium-vanadium steel
• Surface finish: chrome-plated and polished
• Length: 38 mm
• Durability: exceeds DIN 3124 and PN-ISO 1711 requirements
• Edge profile: PRO-DRIVE to reduce point loads and wear

How to use

Select the Proline 38 mm impact socket that matches the fastener size and attach it securely to a compatible impact wrench or driver. Ensure the socket is fully seated on the tool’s drive and on the fastener before applying torque. When using an impact tool, operate at recommended torque and speed ranges and avoid side loading. After use, inspect the socket for cracks, burrs, or deformation and clean and store it in a dry place to maintain the chrome finish and material properties.

Usage recommendations

Use only with impact-rated tools and compatible drive sizes. Do not use a damaged or visibly worn socket. For prolonged service life, avoid excessive side loading, and match the socket to the correct fastener size; periodic inspection and proper storage reduce the risk of tool or fastener damage.
