Ruuvimeisselikärki KS Tools 911.5144 Torx T40 30 mm kuusiokanta

The KS Tools 911.5144 screwdriver bit provides a Torx T40 tip with a 30 mm working length and a hexagonal shank sized to fit 5/16" chucks and bit holders. Designed for precision tasks, this lightweight 10 g bit is suited to repair, assembly and maintenance operations where a reliable Torx engagement and compact bit length are required.

Advantages

This Torx T40 bit offers precise fitment to Torx fasteners, reducing the chance of cam-out and fastener damage. The 30 mm length balances access and control, allowing work in confined spaces while maintaining stability. A hexagonal shank ensures secure seating in standard 5/16" bit holders and quick-change systems. The low weight makes it easy to handle during repetitive tasks and convenient to carry in tool kits.

Suitable for (tasks / use cases)

• Automotive interior and trim fastening where Torx T40 fasteners are used
• Appliance repair and maintenance that requires a 30 mm bit reach
• Assembly lines and production benches with 5/16" hex bit holders
• General DIY and workshop tasks involving Torx fasteners

Key specifications

• Tip type: Torx T40
• Length: 30 mm working length
• Shank shape: Hexagonal
• Shank size: 5/16" compatible
• Weight: 10 g

How to use

Insert the hexagonal shank into a compatible 5/16" bit holder, quick-change chuck or manual bit driver until it seats securely. Align the Torx T40 tip with the fastener and apply steady axial pressure while turning to engage the Torx profile fully. For removal, reverse the rotation while maintaining axial pressure. Use controlled torque to avoid stripping fasteners; pair with an appropriate torque-limiting driver if precise torque is required.

Recommendations

For extended bit life and consistent performance, avoid excessive side loads and use the bit with drivers or holders that provide firm axial support. Inspect the tip for wear before precision tasks and replace the bit if deformation or rounding is visible.
