Nut driver Facom A.404 — single-piece nut driver, model A.404 by Facom

Facom A.404 is a single-piece nut driver designed for driving and tightening nuts in maintenance, assembly and DIY tasks. It is supplied as one unit and offers a straightforward tool solution where a dedicated nut driver is required. The tool is intended for general fastening work and fits applications that call for a compact, purpose-built driver rather than a multi-bit set.

Advantages

The single-piece construction provides stable torque transfer and reduces the risk of bit wobble or loosening. Its dedicated design simplifies operation by eliminating the need to change bits, and the tool’s compact form makes it easy to handle in confined spaces. As a product from a recognized manufacturer, it follows typical quality and durability expectations for workshop and home use.

Suitable for

• Routine maintenance and equipment assembly
• DIY projects at home that require reliable nut tightening
• Electrical cabinets, mechanical fittings and small machinery maintenance
• Situations where a single, fixed driver is preferred over interchangeable sets

When it may not be suitable

This single-piece nut driver is not intended for tasks that require variable bit sizes or a full multi-bit kit; if you frequently work with many different fastener types, a set with interchangeable bits may be more efficient. It is also not designed for high-torque industrial tightening where power tools or torque-controlled wrenches are required.

Key specifications

• Tool type: single-piece nut driver
• Intended use: driving and tightening nuts and fasteners
• Supply format: sold as one unit per pack
• Typical applications: maintenance, assembly, DIY
• Form factor: compact, fixed-head driver for hand use

How to use

Select the nut driver and place the socket end squarely over the nut or fastener. Apply steady hand torque, keeping the driver aligned with the fastener axis to avoid rounding the nut. For repetitive tasks, maintain a controlled grip and reposition your hand as needed to preserve leverage and comfort. Inspect the driver and fastener for wear or damage before use and avoid applying excessive force beyond hand-tightening limits.

What to consider before purchase

• Confirm the nut driver size matches the nut or bolt head you intend to work with.
• Evaluate whether a single fixed driver meets your needs or if an interchangeable bit set is more appropriate.
• Consider the types of tasks and torque levels you typically encounter to ensure hand operation is sufficient.

Usage recommendations

Use the nut driver for hand-tightening and light-to-moderate fastening tasks. Keep the tool clean and inspect the socket interface for wear. When increased torque is required, switch to a torque-rated tool or a powered driver appropriate for the application.
