Tool set Isma PROFI 94 pcs 1/4" & 1/2" hex sockets 4–22 mm

The Isma PROFI 94-piece tool set includes metric 6-point hex sockets with 1/4" and 1/2" drives in sizes from 4 mm to 22 mm, designed for a wide range of mechanical, automotive and maintenance tasks. The set groups sockets for light-duty work with the 1/4" drive and for higher-torque applications with the 1/2" drive, providing a compact solution for repair, assembly and workshop use where reliable metric hex sockets are required.

Advantages

The Isma PROFI set offers a comprehensive size range that reduces the need to switch between individual tools. With both 1/4" and 1/2" drives included, the kit covers delicate fasteners and heavier torque requirements in one collection. The 6-point (hex) socket geometry is appropriate for standard hex fasteners and helps distribute torque across flats rather than corners. The organized set simplifies storage and transportation, enabling quick selection of the correct socket for the job.

Suitable for

• Routine automotive repairs and maintenance
• Assembly and disassembly of machinery and equipment
• General mechanical workshop tasks and field service work
• Home DIY projects requiring metric hex sockets

How to use

Select the socket matching the fastener size, attach it securely to the appropriate drive (1/4" for lighter work, 1/2" for higher torque), and engage the socket onto the fastener squarely to avoid slippage. Use a compatible ratchet, breaker bar or extension as required by the torque and access conditions. Store sockets in the provided case or organizer to maintain order and protect individual pieces from damage.

Usage recommendations

Use the 1/4" drive sockets for smaller fasteners and precision tasks; switch to the 1/2" drive when greater torque is required. Avoid using worn or damaged sockets on fasteners to prevent rounding. Apply appropriate torque settings and follow manufacturer specifications for fasteners to ensure safe and effective results.
