Tool set Isma IS-4941-5DS — 94-piece 1/4" & 3/8" hex sockets (4–22 mm)

Isma IS-4941-5DS — 94-piece 1/4" & 3/8" hex sockets (4–22 mm) is a comprehensive metric socket set that combines two common drive sizes to cover a wide range of tightening and loosening tasks. The kit contains 6-point (hex) sockets in metric sizes from 4 mm up to 22 mm, supplied alongside compatible drive tools and accessories to support general mechanical, automotive and household repairs. The configuration of both 1/4" and 3/8" drives makes the set adaptable for work on small fittings as well as medium-sized fasteners.

Advantages

The set offers a broad selection of metric hex sockets in 6-point design, which helps ensure secure grip on hex fasteners and reduces the risk of rounding. Including both 1/4" and 3/8" drives increases versatility for different torque requirements and access conditions. The organized kit layout keeps components accessible and simplifies transport and storage. The range of socket sizes from 4 mm to 22 mm covers common repair and maintenance tasks, reducing the need to purchase individual sockets separately.

Suitable for

• General mechanical maintenance and assembly work
• Automotive repairs and light vehicle servicing
• Household fixtures, furniture assembly and appliance maintenance
• Hobbyist projects requiring metric hex sockets

Key specifications

• Socket type: 6-point (hex) metric sockets
• Drive sizes included: 1/4" and 3/8"
• Socket size range: 4 mm to 22 mm
• Number of pieces: 94
• Intended use: tightening and loosening hex fasteners
• Kit format: organized case or tray for storage and transport

How to use

Select the socket matching the metric size of the hex fastener, attach it securely to the appropriate drive (1/4" for smaller fasteners, 3/8" for medium torque tasks) and engage the drive tool with the fastener head. Apply steady force while maintaining alignment to avoid slippage. For higher torque needs, use the larger drive; for confined spaces or lower-torque operations, use the smaller drive. After use, clean sockets of debris and return them to the designated slots in the case to keep the set organized.

Usage recommendations

Use suitable personal protective equipment and appropriate torque values for the application. Avoid using damaged or worn sockets on fasteners, and do not use sockets as hammers or pry bars. Store the set in a dry place to prevent corrosion and periodically inspect sockets for wear or rounding before critical tasks.
