## Summary description

Dedra 17F040Z is a single-piece hex key (Allen wrench) with a 1/2" imperial size. Designed for driving hex-head screws and bolts, it suits workshop, maintenance and assembly tasks requiring a larger imperial hex size. Compact and simple, it is intended for manual torque applications and access to recessed fasteners.

## Long description

Socket bit Torx 1/2" T20 L55mm from Dedra is a single-piece insert designed for use with 1/2" drive ratchets, breakers and compatible impact tools. The T20 profile matches Torx fasteners to provide accurate engagement and reduce cam-out during fastening and loosening operations. At 55 mm length the bit gives reach into recessed or semi-recessed screws while keeping a compact working profile suitable for automotive, mechanical and assembly environments.
Advantages
The bit provides precise Torx T20 engagement for reliable torque transfer and reduced fastener wear. Manufactured for compatibility with 1/2" drive tools, it supports both hand-operated ratchets and impact drivers within the bit’s intended application range. Its 55 mm length balances access and control, allowing work in tighter spaces without excessive leverage loss. The single-piece construction ensures consistent alignment and straightforward insertion into sockets or tool holders.
Suitable for
 Automotive fastener removal and installation where Torx T20 is used
 Mechanical repairs and maintenance involving Torx-headed screws
 Assembly and disassembly of equipment and appliances with Torx T20 fasteners
 Work requiring use with 1/2" drive ratchets or compatible impact tools
Key specifications
 Drive size: 1/2" compatible
 Tip type: Torx T20
 Overall bit length: 55 mm
 Material and finish: durable tool steel construction suitable for torque applications (manufacturer-specified)
 Fit characteristic: precision-machined T20 profile for secure engagement
How to use
Select the Dedra Torx 1/2" T20 L55mm bit and insert it securely into a compatible 1/2" drive socket or bit holder. Engage the corresponding Torx T20 screw head squarely to ensure full contact between the bit profile and the fastener. Apply torque gradually when tightening to avoid over-torquing; when loosening, use steady applied force to prevent stripping. For impact tool use, verify the bit and tool are rated for impact applications and inspect the bit for wear before each use.
Usage recommendations
Use the bit with appropriate personal protective equipment and the correct 1/2" drive tool. Avoid excessive side loading or prying to prevent premature wear or damage. Replace the bit if visible rounding or deformation appears on the Torx profile.
