Bit socket Wera 05003371001 8767 A HF Torx TX 40 1/4" drive red

The Wera 8767 A HF Torx TX 40 bit socket with 1/4" drive and holding function is a compact insert designed for secure engagement with Torx TX 40 fasteners. With a length of 28 mm and a distinctive red finish, this bit socket provides accurate torque transfer and improved visibility in a toolbox. It is intended for use with 1/4" drive ratchets, bit holders or compatible power tool adapters and is suitable for both professional technicians and home users who require a reliable Torx interface for assembly and maintenance tasks.

Advantages

This bit socket combines a precise Torx geometry for optimum contact with TX 40 screws and a holding function that keeps fasteners on the bit during positioning and initial threading. The 28 mm length balances accessibility with control in confined spaces, and the robust construction ensures consistent torque transmission while resisting wear. The red finish aids quick identification among other bits and sockets.

Suitable for

• Assembly of equipment and machinery that use Torx TX 40 fasteners
• Maintenance and repair work requiring secure bit retention and quick screw alignment
• Use with 1/4" drive ratchets, bit drivers, and power tool adapters
• Automotive, electronics, and industrial applications where precise Torx engagement is needed

Key specifications

• Bit type: Torx (TX 40)
• Drive size: 1/4"
• Length: 28 mm
• Feature: Holding function for secure screw retention
• Finish: Red for visibility

How to use

Select a compatible 1/4" drive tool (ratchet, bit holder or adapter) and insert the bit socket until it seats securely. Engage the Torx TX 40 fastener by aligning the Torx profile and applying steady torque to avoid cam-out. Use the holding function to retain the screw on the bit while positioning, then complete tightening to the required torque specification for the application. Remove the bit socket by pulling it from the tool when the operation is finished and store it to prevent corrosion and damage.

Usage recommendations

Inspect the bit tip regularly for wear and replace when rounding or damage occurs. Use the correct torque values for fasteners to prevent stripping. Keep the bit socket clean and free of debris; the holding function is most effective when the contact surfaces are intact and undamaged.
