Socket set Stanley FATMAX TSTAK 3/8 inch Metric FMHT0-74296

The Stanley FATMAX TSTAK 3/8 inch Metric socket set is a compact, organized collection of sockets and accessories for metric fasteners. Designed for workshops, service vehicles and home toolboxes, the set combines a 3/8 inch drive ratchet with a range of metric socket sizes housed in a TSTAK-compatible case for secure storage and easy transport. The construction and finish of the tools focus on reliable torque delivery and resistance to everyday wear.

Advantages

The set offers a balanced combination of durability and user convenience through a 3/8 inch drive suited for general service work and maintenance tasks. Sockets are machined to fit metric fasteners precisely, reducing rounding and slippage. The TSTAK case provides modular storage compatibility, protecting tools from loss and allowing stacking with other TSTAK modules. The ratchet mechanism is built for repeated use and provides efficient socket engagement and release.

• Mobile service kits in service vans or toolboxes

Key specifications

• Drive size: 3/8 inch
• Metric socket range: multiple common metric sizes for general use

How to use

Select the appropriate metric socket for the fastener, attach it to the 3/8 inch drive ratchet and ensure a full engagement on the fastener head before applying torque. Use the ratchet switch to change rotation direction and apply steady, controlled force to avoid sudden slips. When working in confined spaces, use extensions or universal joints included in the set to reach recessed fasteners. After use, clean sockets and ratchet surfaces and return tools to the TSTAK case to maintain organization and protect the tool finish.

Usage recommendations

For safe and long-lasting performance, avoid using the sockets with impact tools unless they are specifically rated for impact use. Regularly inspect the ratchet mechanism and socket drive faces for wear, and keep the tools clean and lightly lubricated to preserve smooth operation and prevent corrosion.
