Hex key set Vorel 56391 — 10-piece Allen key set, metric

Vorel 56391 is a 10-piece metric hex key (Allen key) set supplied as a single compact pack. The set includes ten commonly used sizes for driving hexagonal socket fasteners in assembly, maintenance and repair tasks. Each key is made from chrome-vanadium steel with a satin finish, offering a balance of strength and corrosion resistance while remaining suitable for handheld use in workshops, garages and at-home tool kits.

Advantages

The hex keys are produced from CR-V chrome-vanadium steel, providing enhanced durability and resistance to wear during repeated use. The satin finish reduces glare and helps resist surface corrosion. The included range of metric sizes from small to large covers typical fasteners used in furniture assembly, bicycle maintenance and mechanical repairs, minimizing the need to switch between different toolsets. The compact single-pack format keeps the keys together for convenient storage and transport.

Suitable for

• Assembly of furniture and flat-pack items
• Bicycle maintenance and component adjustments
• Small engine and machinery maintenance
• General workshop and garage repairs
• Home DIY and hobby projects requiring metric hex fasteners

How to use

Select the hex key size that fits the hexagonal socket of the fastener without play. Insert the short or long arm into the socket depending on required reach and leverage, and turn clockwise to tighten or counterclockwise to loosen. Use the long arm for greater torque and the short arm for access in confined spaces. Maintain straight alignment between key and fastener to avoid rounding.

Usage recommendations

Preferred practice is to keep the keys clean and dry after use and store them together in their pack to prevent loss. For high-torque applications, consider using a properly sized bit or wrench designed for higher torque to avoid damaging the hex key or fastener. Inspect keys periodically for wear or deformation and replace if edges show rounding.
