Jonnesway hex ball-end screwdriver bit 4x75 mm, 6‑point 10 mm (D175H40)

Jonnesway hex ball-end screwdriver bit 4x75 mm, 6-point 10 mm (D175H40) is a precision tool bit designed for driving hex fasteners where angled access is required. The 4×75 mm shank and 6-point 10 mm ball-end geometry provide reliable contact with hex heads while permitting slight angular deviation between driver and fastener, improving reach in confined or obstructed areas. It is compatible with standard bit holders for hand or powered use and is intended for workshop, automotive and general maintenance tasks.

Advantages

The ball-end design allows insertion at an angle, enabling access to fasteners that cannot be reached with a straight bit. The 6-point tip provides good torque transfer and reduced rounding compared with some lower-precision profiles. The 4×75 mm length offers a balance between reach and control, and the bit’s construction is suitable for repeated use in typical workshop and automotive environments.

Suitable for

• Reaching hex fasteners in tight or angled spaces
• Automotive repair and maintenance tasks
• Workshop assembly and disassembly where offset access is needed
• Use with hand drivers and powered bit holders

Key specifications

• Tip type: 6-point hex ball-end
• Tip size: 10 mm
• Shank dimensions: 4 × 75 mm
• Compatibility: standard 4 mm hex bit holders and adapters
• Typical applications: angled access to hex fasteners, confined-space fastening

How to use

Insert the bit securely into a compatible bit holder or driver. Place the ball-end tip into the hex fastener and apply steady axial pressure while driving. The ball-end permits a degree of angular engagement — align the driver as needed but avoid excessive side loading. For powered use, select appropriate torque settings to prevent fastener or bit damage. Inspect the bit tip for wear before use and replace when rounding or deformation is visible.

Usage recommendations

Use the bit for tasks that require angled entry or extra reach; avoid using it as a pry tool or under impact conditions for which it was not designed. Keep the tip clean and free of debris to maintain contact quality and reduce wear.
