DEDRA 17F051Z hex key 1 pc(s)

Dedra Torx socket bit for 1/2" drive, size T25 and length 100 mm is a purpose-built tool insert that fits any 1/2" square drive ratchet, torque wrench or compatible power tool. The 100 mm length provides extended reach to access recessed or hard-to-reach Torx T25 fasteners commonly found in automotive, mechanical and assembly applications. The bit is designed for precise engagement with Torx heads to reduce cam-out and protect fastener geometry during tightening or loosening.

Advantages

The hardened and precisely machined Torx tip ensures accurate fitment into T25 fasteners, improving torque transfer and minimizing wear on both bit and fastener. Its 1/2" square drive connection allows use with a wide range of hand and power tools, while the 100 mm shank length gives additional clearance for components and obstacles. The straightforward design makes it easy to combine with extensions, adapters and impact tools for varied workshop tasks.

Suitable for

• Automotive repair and maintenance where Torx T25 fasteners are used
• Mechanical assembly and disassembly in equipment and machinery
• Electro-mechanical and furniture assembly tasks requiring extended reach
• Use with ratchets, torque wrenches, impact drivers and socket extensions

Key specifications

• Drive size: 1/2" square drive compatibility
• Bit type: Torx T25
• Overall bit length: 100 mm
• Material and heat treatment: hardened steel construction for durability and wear resistance
• Tip geometry: precision-machined Torx profile to reduce cam-out

How to use

Insert the 1/2" square drive into the corresponding ratchet, torque wrench or impact tool and confirm secure seating. Position the Torx T25 tip into the fastener head, ensuring full engagement of the torx profile before applying torque. For removal or installation, apply steady, controlled force and avoid sudden impacts unless using an impact-rated tool. When using with a torque wrench, set the required torque value and operate the wrench according to the tool manufacturer's instructions.

Usage recommendations

Use the bit that matches the fastener size precisely to prevent rounding; when working with high torque or impact tools, verify that the bit and the tool are rated for such use. Store the bit in a clean, dry tool organizer to avoid corrosion and check the tip for wear before precision tasks.
