Hex Key (Allen Wrench) 17.0 mm, Dedra 06F037, CRV steel, long

Long 17.0 mm hex key (Allen wrench) by Dedra is a single-piece hand tool made from chrome-vanadium (CRV) steel. It is shaped with a long arm to increase reach and leverage when turning hexagonal socket fasteners. The tool is intended for assembly, maintenance and repair tasks where access to recessed or deep-set bolts is required; its solid construction provides consistent torque transmission for workshop, garage, and industrial use.

Advantages

The long arm design offers improved access to fasteners located deep within assemblies and provides greater mechanical advantage compared with short hex keys. Manufactured from CRV steel, the wrench combines strength and wear resistance for repeated use. Its precise hex profile ensures reliable engagement with fastener heads, reducing the risk of rounding. The single-piece construction minimizes flex and delivers stable torque transfer.

Suitable for

• Tightening and loosening hex socket bolts in machinery and equipment
• Assembly and disassembly of furniture and metal frames with recessed fasteners
• Maintenance tasks in automotive and workshop environments
• Accessing deep-set fasteners in appliances or industrial installations

Key specifications

• Key size: 17.0 mm
• Material: chrome-vanadium (CRV) steel
• Shape: long arm hex key (L-shape) for extended reach
• Finish: metal/crv finish suitable for workshop use
• Drive type: hex (Allen) socket engagement

How to use

Insert the short or long end of the hex key into the hexagonal socket of the fastener so that the hex profile seats fully in the recess. Use the long arm for reach or to apply higher leverage by holding the short arm, or use the short arm for increased torque when space allows. Apply steady, controlled force to avoid cam-out or rounding of the fastener head. After use, wipe the tool to remove debris and store it in a dry place to reduce corrosion.

Usage recommendations

Choose the long 17.0 mm Dedra hex key when you need extended reach or when working with deep-set hex bolts. Match the key size precisely to the fastener to prevent damage. Avoid excessive force beyond the tool's capacity; if a fastener is seized, consider applying penetrating lubricant and using an appropriate-impact or higher-capacity tool rather than risking damage to the hex key or fastener.
