Torx T40 Long Bit Key, Dedra CRV (model 06F120)

Long Torx T40 Bit Key from Dedra is a single-piece long-reach Torx driver made of chrome vanadium (CRV) steel. It is designed to engage T40 Torx fasteners located in recessed, deep or otherwise hard-to-reach positions. The slim long shank and precisely machined Torx tip provide accurate fit and transfer of torque for maintenance, assembly and repair applications.

Advantages

The chrome vanadium construction offers improved strength and wear resistance compared with standard steels, while the extended length provides extra reach for recessed fasteners without compromising control. The precisely formed Torx head reduces cam-out and helps protect fastener heads during repeated use. Its compact single-bit design simplifies storage and handling in mobile toolkits.

Suitable for

• Automotive repair and maintenance where T40 fasteners are recessed
• Machinery assembly and servicing with deep-set Torx screws
• Appliance and equipment repair in confined spaces
• General workshop and field service tasks requiring long-reach Torx access

Key specifications

• Drive type: Torx T40
• Material: chrome vanadium (CRV) steel
• Form: long-shank bit key for extended reach
• Finish: machined tip for precision engagement
• Use: hand-driven Torx bit for insertion into compatible bit holders or key sockets

How to use

Insert the Torx T40 long bit key into a compatible holder or directly into the screw head, ensuring the tip fully seats in the fastener recess before applying torque. Use steady, controlled turns to avoid stripping the fastener; if additional leverage is required, mount the bit in an appropriate handle or key that accepts this style of bit. After use, clean any debris from the tip and store the bit in a dry place to preserve the finish and prevent corrosion.

Usage recommendations

For best results, match the Torx T40 long bit key with correctly sized fasteners and avoid excessive side loading which can bend the long shank. When working in tight or deep locations, support the tool to maintain alignment and reduce wear on the bit and fastener head.
