Tool set Rockforce RF-41421-5GOLD — 142+6 pcs sockets and accessories 1/4", 3/8", 1/2" (4–36 mm)

Rockforce RF-41421-5GOLD — 142+6-piece socket and accessory set provides a comprehensive selection of metric sockets and drive tools in 1/4", 3/8" and 1/2" drive sizes. The set covers hex (6-point) and bi-hex (12-point) sockets from 4 mm up to 36 mm and includes a range of accessories commonly used for mechanical and automotive work. The kit is arranged to offer quick access to common and extended sizes needed for maintenance, repair and assembly tasks.

Advantages

The set combines three drive sizes in one organized kit, enabling work with small, medium and large fasteners without switching between separate sets. Inclusion of both 6-point and 12-point sockets increases compatibility with different bolt head geometries and provides options for confined access. Accessories such as extensions, universal joints and ratchets expand reach and improve leverage, while the wide metric range from 4 mm to 36 mm minimizes the need for additional tools.

Suitable for

• Automotive repair and servicing — engine, suspension and brake components
• Mechanical maintenance and equipment assembly
• Home DIY projects requiring metric sockets and common accessories
• Workshop and professional service use where multiple drive sizes are needed

Key specifications

• Number of pieces: 142+6 pieces total in the complete set
• Drive sizes included: 1/4", 3/8", 1/2"
• Socket types: 6-point (hex) and 12-point (bi-hex) sockets
• Metric size range: 4 mm to 36 mm
• Accessories included: ratchets, extensions, universal joint(s) and other common socket accessories
• Organizational format: fitted case or tray for sorted storage and transport

How to use

Select the appropriate drive size and socket according to the fastener size and head type, then attach the socket to the ratchet or extension. For confined spaces use the 12-point sockets or a universal joint to gain access. Apply steady, controlled force and avoid sudden impacts when working with standard ratchets. Use extensions to reach recessed fasteners and switch to a larger drive for higher torque requirements when necessary.

Usage recommendations

Inspect sockets and accessories periodically for wear or damage, keep the set clean and lightly lubricate moving parts of ratchets. Use torque-controlled tools for fasteners that require specified torque values and avoid using these sockets with impact tools unless they are specifically rated for impact use.
