Impact socket accessory Proline ZR18430, length 48 mm

Proline ZR18430 is an impact-rated hexagonal socket accessory with a length of 48 mm, designed for use with impact wrenches and pneumatic or electric impact drivers. Manufactured from chromium-molybdenum (CrMo) steel, this socket offers increased tensile strength and a higher yield point compared with standard chromium-vanadium sockets, making it suitable as a replacement or spare for fastening and loosening bolts and nuts under demanding conditions.

Advantages

The chromium-molybdenum construction ensures extended working life and improved resistance to deformation under high torque. A specially profiled rounded geometry of the internal corners—Proline's PRO-DRIVE system—reduces concentrated point loads on bolt edges and the socket walls, enabling greater torque transfer without premature failure. The square drive interface is compatible with common locking mechanisms used in pneumatic tools, and the socket is supplied in protective retail packaging.

Suitable for

• Automotive maintenance and repair where impact-rated sockets are required
• Industrial assembly and disassembly with pneumatic impact wrenches
• Mechanical workshops and professional service garages
• DIY projects that involve high torque fastening or stubborn fasteners

Key specifications

• Shape: Hexagonal (6-point) impact socket
• Length: 48 mm
• Material: Chromium-molybdenum (CrMo) steel
• Internal corner profile: Rounded PRO-DRIVE geometry to reduce point loads
• Drive type: Square drive compatible with standard impact tool locking mechanisms
• Recommended use: Impact-rated fastening and loosening of bolts and nuts
• Packaging: Retail cardboard box or hanger

How to use

Select the socket size matching the bolt or nut head, mount the socket onto the square drive of the impact wrench or driver until it locks in place, then apply controlled bursts of impact torque to loosen or tighten the fastener. Use appropriate torque settings on the impact tool where available and avoid prolonged continuous operation at maximum torque to reduce wear. After use, inspect the socket for cracks, deformations, or rounding of the internal profile and replace if any damage is found.

Usage recommendations

For best results use with impact-rated extensions and adapters, and pair with a torque-limiting device when precise torque values are required. Store in a dry place to avoid corrosion and clean off debris after heavy use to maintain the PRO-DRIVE internal profile and prolong service life.
