Impact Socket Proline 18491 — heavy-duty impact socket, model 18491 by Proline

Proline 18491 is a heavy-duty impact socket designed for use with impact wrenches and pneumatic or electric impact drivers. Made from chromium-molybdenum (Cr-Mo) steel and heat-treated for impact work, this socket provides the mechanical strength and toughness required for high-torque fastening and loosening tasks. The Proline 18491 is suitable for professional and DIY mechanical work where impact-rated hardware is required and is compatible with standard impact tool interfaces.

Advantages

The chromium-molybdenum construction gives the Proline 18491 enhanced resistance to fracture and deformation under repeated impact loading. Heat treatment and controlled manufacturing tolerances improve wear resistance and maintain fit on fasteners during heavy use. The socket is designed to withstand high torque from pneumatic and electric impact drivers while minimizing damage to the socket and the fastener head.

Suitable for

• Automotive wheel and brake maintenance with impact wrenches
• Heavy equipment assembly and maintenance
• Industrial and workshop fastening tasks requiring impact-rated sockets
• DIY projects that involve high-torque nuts and bolts

Key specifications

• Material: chromium-molybdenum (Cr-Mo) steel, heat-treated for impact use
• Intended use: impact wrench and impact driver applications
• Construction: heavy-duty, impact-rated design
• Compatibility: fits standard impact tool interfaces (square drive compatible with impact tools)
• Durability: enhanced resistance to cracking and deformation under repeated impacts

How to use

Select the correct socket size for the fastener, ensure the impact tool and socket square drive match, and attach the socket firmly to the impact wrench or driver. Use the impact tool according to its operating instructions, applying steady bursts of torque as required. Inspect the socket before and after use for signs of wear or damage and replace it if cracking, excessive rounding, or deformation is observed. Ensure appropriate personal protective equipment is used when working with impact tools.

Usage recommendations

For best performance and safety, use the Proline 18491 only with impact-rated tools and accessories. Avoid using the socket on non-impact hand tools, as that can increase the risk of damage to the socket or fastener. Store the socket in a dry, clean environment and inspect regularly for wear. When removing stubborn fasteners, use controlled torque settings and appropriate extensions or adapters rated for impact use.
