Tool set Isma 109-piece 1/2" & 1/4" hex sockets 4–22 mm

Isma 109-piece tool set with 1/2" and 1/4" drives contains a comprehensive selection of 6-point (hex) sockets in metric sizes from 4 mm to 22 mm. The set combines two drive sizes to cover a wide range of fastening and loosening tasks, making it suitable for general mechanical work, automotive maintenance, household repairs and professional service environments where both fine and high-torque operations are needed.

Advantages

The kit provides a broad range of commonly used metric socket sizes in a single organized set, eliminating the need to switch between multiple individual tools. Inclusion of both 1/2" and 1/4" drives allows use with ratchets and accessories for high-torque jobs as well as delicate, precision tasks. Hex (6-point) sockets reduce cam-out and improve contact with fasteners, and the compact case keeps sockets and accessories sorted for quick access on the job.

• Automotive maintenance and repair
• General mechanical assembly and disassembly
• Household DIY and furniture installation
• Professional service and workshop use

How to use

Select the socket matching the fastener size, attach it to the appropriate drive (1/4" for low-torque or tight spaces, 1/2" for higher torque tasks) and fit the socket onto a compatible ratchet or extension. Apply steady, controlled force in the correct rotation direction to tighten or loosen fasteners. Change sockets as needed to match different metric fastener sizes, and return components to the case after use to maintain organization.

Usage recommendations

For safe and durable results, use the 1/4" drive for smaller fasteners and confined spaces, and the 1/2" drive when higher torque is required. Inspect sockets and ratchets before use for wear or damage, and avoid excessive impact or using sockets on rounded or damaged fastener heads.
