Jonnesway screwdriver bit D130H80 — 8 x 30 mm hex (6-point) 10 mm

Jonnesway screwdriver bit D130H80 is an 8 x 30 mm ampoule-style hex bit with a 6-point 10 mm head designed for use with compatible bit holders, manual drivers and power tools. The compact 30 mm length and 8 mm shank diameter make it suitable for confined spaces while providing the engagement profile required for 10 mm 6-point fasteners. This replacement bit is made to fit standard 8 mm quick-change chucks and bit adapters commonly used in mechanical, automotive and maintenance work.

Advantages

The bit combines a short, ampoule-style profile with a 6-point head geometry to reduce rounding on hex fasteners and deliver reliable torque transfer. Its standardized 8 mm shank provides compatibility with many bit holders and impact drivers. The compact 30 mm length improves access in tight assemblies and recessed fasteners without sacrificing driving control.

Suitable for

• Automotive repair and component assembly where 10 mm 6-point fasteners are used
• General mechanical maintenance and machinery servicing
• Tight or recessed fastening points requiring a short ampoule-style bit
• Use with manual drivers, ratchet bit holders and compatible power tools

Key specifications

• Shank diameter: 8 mm
• Overall bit length: 30 mm (ampoule-style)
• Head type: hex, 6-point
• Head size: 10 mm
• Intended use: fastening and loosening 10 mm 6-point fasteners

How to use

Insert the 8 mm shank securely into a compatible bit holder, quick-change chuck or driver. Align the 10 mm 6-point head with the fastener and apply steady axial pressure while driving to ensure full engagement and reduce the risk of cam-out or rounding. For power tools, start at low speed to confirm alignment before increasing torque. Remove the bit after use and inspect the head for wear before reuse.

Usage recommendations

Use with tools rated for the intended torque and, when working on critical or high-torque fasteners, consider torque-limiting drivers or controlled-speed impact drivers. Regularly inspect the bit for deformation or wear and replace it if the 6-point profile shows rounding to avoid damaging fasteners.
