Impact Socket Set STAHLWILLE ROCKFORCE RF-50121K, 25 pcs, 1/2" and 1/4" drives, 6-point sockets 4–32 mm

The STAHLWILLE ROCKFORCE RF-50121K impact socket set is a 25-piece collection designed for professional workshop and industrial use. The set includes both 1/2" and 1/4" drives and a range of 6-point sockets from 4 mm to 32 mm, covering common fastener sizes encountered in automotive maintenance, machinery repair, and assembly tasks. Sockets are impact-rated and intended for use with impact wrenches and pneumatic tools, providing the strength and durability required for high-torque applications.

Advantages

The sockets feature a 6-point profile that reduces rounding of fasteners and concentrates torque on wrench flats. Impact-rated construction increases resistance to fracturing under repeated shock loads and extends tool life in demanding environments. Inclusion of both 1/2" and 1/4" drives allows flexible use across a wide variety of fastener sizes without the need for adapters. Organized storage in a compact case keeps the set transportable and accessible for mobile technicians and stationary workshops.

Suitable for

• Automotive repair and maintenance
• Industrial machinery servicing
• Mechanical assembly and disassembly
• Pneumatic and electric impact wrench applications
• Field service and mobile technicians

Key specifications

• Number of pieces: 25
• Drive sizes: 1/2" and 1/4"
• Socket profile: 6-point
• Socket size range: 4 mm to 32 mm
• Intended use: impact-rated sockets for use with impact wrenches and pneumatic tools

How to use

Select the correct socket size for the fastener to ensure full engagement of the 6-point profile. Attach the socket to a compatible 1/2" or 1/4" impact wrench or driver, making sure the drive fits securely. Operate the impact tool following the manufacturer's safety and operating instructions, using appropriate torque settings and wearing personal protective equipment. After use, clean sockets of debris and store them in the supplied case to prevent loss and corrosion.

Usage recommendations

Use impact-rated sockets exclusively with impact tools; do not use them with manual chrome-plated ratchets or breaker bars where corrosion-resistant finish or precise torque control is required. Regularly inspect sockets for cracks or deformation and replace any damaged pieces. Apply appropriate lubricants to fasteners as recommended for the application to reduce wear on both sockets and fasteners.
