1" Impact Socket 51 mm (6-point) Rockforce RF-48551

Rockforce 1" impact socket 51 mm (6-point) is a heavy-duty hex socket designed for use with 1-inch drive impact wrenches and breakers. Built to fit 51 mm hex fasteners and nuts, this impact-rated socket provides the contact geometry and wall thickness required for repeated high-torque applications in automotive, industrial and heavy-equipment maintenance.

Advantages

The 6-point profile reduces rounding of hex fasteners by maximizing contact area on the flats. Manufactured for impact use, the socket features thicker walls and a robust drive connection to resist deformation and cracking under repeated hammering torque. Its precise 51 mm dimension ensures a snug fit on matching nuts, while the 1" drive interface provides compatibility with standard heavy-duty impact tools. The socket’s construction prioritizes durability and safe transfer of torque.

Suitable for

• Removing and installing 51 mm hex nuts on heavy machinery
• Automotive axle, hub and suspension service where high torque is required
• Industrial maintenance and assembly with 1" impact wrenches
• Field service and construction equipment maintenance

Key specifications

• Drive size: 1 inch (1")
• Socket opening: 51 mm
• Point configuration: 6-point (hex)
• Intended use: Impact-rated for use with impact wrenches and breakers
• Material characteristics: heavy-duty construction with reinforced walls for torque resistance

How to use

Select the socket to match the 51 mm hex fastener and attach it securely to a compatible 1" drive impact wrench or breaker. Ensure the socket is fully seated on the nut before applying torque. When using an impact tool, apply torque in controlled bursts and avoid side loading to reduce stress on the socket and fastener. After use, inspect the socket for visible cracks, deformation or wear and replace if any damage is found.

Usage recommendations

Use protective eyewear and follow the impact tool manufacturer’s safety instructions. For critical fasteners, apply torque in stages and verify final torque with appropriate calibrated tools when required.
