Bit de chave de fendas Wera Tieflochbit 70 mm T40 6,3 mm 1/4 polegadas sextavado

The Wera Tieflochbit 70 mm T40 is a long screwdriver bit designed for accessing deep-set or recessed Torx fasteners. It features a 70 mm working length and a T40 Torx tip for precise engagement with matching fasteners. The bit has a 6.3 mm (1/4") hexagon shank that fits common 1/4" bit holders and tools that accept hex shanks, enabling use with hand drivers, powered screwdrivers, and many impact drivers where compatible.

Advantages

The extended 70 mm length allows reach into narrow or recessed screw positions without resorting to improvised extensions. The Torx T40 geometry ensures stable, slip-minimizing contact with fasteners, reducing cam-out and wear on both screw and bit. The standardized 6.3 mm (1/4") hexagon shank provides broad compatibility with bit holders and quick-change chuck systems, supporting efficient bit changes and reliable torque transfer.

Suitable for

• Accessing recessed or deep Torx T40 fasteners in machinery and assemblies
• Workshop maintenance and repair tasks requiring extended reach
• Assembly line operations where quick bit changes and repeatable torque are needed
• Use with manual bit drivers, power screwdrivers, and compatible impact drivers

Key specifications

• Working length: 70 mm
• Tip type: Torx T40
• Shank: 6.3 mm (1/4") hexagon
• Material and heat treatment suitable for regular workshop and assembly use

How to use

Insert the 6.3 mm (1/4") hexagon shank into the compatible bit holder or quick-change chuck until it seats firmly. Align the Torx T40 tip with the corresponding fastener head and apply steady axial pressure while turning the driver to engage the screw. For deep or recessed fasteners, ensure the bit is fully engaged before applying torque to avoid slipping. When using power tools, select an appropriate torque setting and control speed to match the fastener and material.
