Double-sided metric key set 8–17 mm, 6 pieces — faster tools 03-14-0100

The Double-sided metric key set 8–17 mm, 6 pieces from faster tools provides a compact selection of common metric sizes in a space-saving design. Each of the six keys has two working ends, effectively doubling the range of sizes available while keeping the set small enough for a toolbox, glove compartment or service pouch. The set is intended for general automotive, household and mechanical repair tasks where access, versatility and portability are required.

Advantages

The double-ended design reduces the number of separate tools needed and saves storage space without sacrificing coverage of frequently used metric sizes. Durable material and precise machining ensure reliable fit on hex fasteners, reducing rounding and slippage. The compact format makes the set easy to carry and retrieve during on-site repairs or quick maintenance checks.

Suitable for

• Automotive maintenance and light repairs
• Household repairs and furniture assembly
• Mechanical and workshop tasks requiring metric hex keys
• Mobile toolkits and emergency repair kits

Key specifications

• Range of metric sizes: 8 mm to 17 mm (six double-ended pieces covering common intermediate sizes)
• Number of pieces: 6 double-sided keys
• Material and finish: hardened steel with machined hex ends for precise fit (material specified by manufacturer)
• Design: double-ended keys to maximize size coverage while minimizing storage volume
• Intended use: hand-operated metric hex keys for fastening and loosening bolts and nuts

How to use

Select the end of the double-sided key that matches the fastener size, insert the hex end fully onto the bolt or nut, and apply steady torque appropriate to the fastener and application. Use the longer end for increased leverage when space allows, and the shorter end when working in tight clearances. Inspect the mating surfaces for damage before use and replace any key that shows excessive wear to maintain proper fit and safety.

Usage recommendations

Store the set in a dry place to prevent corrosion, and include it in a vehicle or portable repair kit for quick access during roadside or field repairs. For stubborn fasteners, use penetrating lubricant and appropriate safety measures; avoid applying excessive force that can damage fasteners or the tool.
