Adapter Jonnesway AN040043N-4, 4 mm

Jonnesway AN040043N-4 adapter is a 4 mm coupling accessory engineered to connect compatible drivers, bits and sockets. It provides a secure mechanical link for transferring torque between a tool and a 4 mm interface, designed for workshop, automotive repair and general maintenance. The adapter's compact profile enables use in confined spaces and supports precise control when working with small fasteners or assemblies that require a 4 mm connection.

Advantages

This 4 mm adapter offers a reliable mechanical fit and consistent torque transmission while minimizing play between mating parts. Manufactured to meet workshop durability expectations, the adapter's compact form factor improves access in tight areas and facilitates precise handling. Its universal 4 mm interface simplifies compatibility with a range of drivers, bits and sockets that accept the same size connection.

Suitable for

• Small-scale automotive and motorcycle maintenance where a 4 mm interface is specified
• Electronics assembly and repair requiring compact torque transfer
• General workshop tasks and household repairs involving small fasteners
• Precision mechanical work and instrument maintenance with 4 mm tool fittings

Key specifications

• Connection size: 4 mm nominal interface
• Function: torque transfer coupling between driver and bit or socket
• Form factor: compact, low-profile adapter suitable for confined spaces
• Intended use: compatible with tools and sockets designed for a 4 mm connection
• Typical applications: workshop, automotive repair, electronics service, general maintenance

How to use

Align the adapter's 4 mm interface with the mating driver or socket and push until a secure engagement is felt. Ensure the connected tool and accessory are appropriate for the required torque and fastener type. During use, maintain steady, controlled force to avoid sudden torque spikes and check the connection periodically for any wear or loosening. Remove the adapter by pulling it straight from the mating interface when work is complete.

Usage recommendations

Use the adapter with tools and accessories rated for the intended torque range; avoid applying excessive torque beyond the capability of the 4 mm connection. Inspect the adapter for signs of wear or deformation before each use and replace if damage is detected. Store in a dry environment to prevent corrosion and keep compatibility information available when selecting matching drivers or sockets.
