Jonnesway hex socket bit 4x30 mm 6-point 10 mm (D130H40) for hand and power drivers

Jonnesway D130H40 is a hex socket bit sized 4x30 mm with a 6-point 10 mm hex profile, designed for detachable use with compatible hand and power drivers. The bit provides a standard hex interface that fits 10 mm 6-point hex-head fasteners, making it suitable for common fastening and loosening jobs in mechanical, assembly, and maintenance work. Its 4x30 mm dimensions designate the shank and working length to match quick-change bit holders and standard bit chucks.

Advantages

The bit is manufactured to provide a precise 6-point engagement with hex fasteners, reducing rounding and improving torque transfer compared with lower-contact profiles. Its detachable design allows quick replacement between different driver types and the compact 30 mm length gives access to shallow and moderately recessed fasteners. The standard 4 mm shank fits a wide range of bit holders and adapters used in both hand and powered tools.

Suitable for

• Fastening and loosening 10 mm 6-point hex-head bolts and screws
• General mechanical repair and maintenance
• Assembly work requiring standard hex bits and quick bit changes
• Use with compatible hand drivers, bit holders and power driver chucks

Key specifications

• Bit type: hex socket, 6-point profile
• Working size: 10 mm hex
• Shank and length: 4 x 30 mm (shank diameter x overall/working length reference)
• Compatibility: detachable bit for hand and power drivers with standard 4 mm bit holders
• Material and finish: hardened steel construction suitable for general fastening tasks (manufacturer typical treatment)

How to use

Insert the 4 mm shank into a compatible bit holder, quick-change chuck or driver socket until it locks or seats securely. Align the 6-point 10 mm hex end with the fastener head and apply steady torque through the hand tool or power driver. For power drivers, use controlled speed and torque settings appropriate for the fastener and material to avoid over-tightening. Remove the bit by retracting the locking mechanism of the holder or pulling it free when the driver is not under load.

Usage recommendations

Use the bit within the rated torque range of your driver and select appropriate driver settings when using power tools. Inspect the bit for wear or rounding before use and replace if the hex profile shows deformation. Store bits in a dry, organized case to prevent damage and ensure quick selection.
