Hex Allen Key Set Sourcing YT-05634, 9 pcs, sizes 1.5–10 mm

The Sourcing YT-05634 hex (Allen) key set contains nine metric L-shaped keys covering sizes from 1.5 mm to 10 mm. Designed for general assembly, maintenance and repair tasks, this compact set provides the most commonly used small and medium sizes for working with furniture fittings, bicycles, electronics enclosures and light machinery. The tools are intended for workshop, garage and household use where reliable torque and access to recessed hex fasteners are required.

Advantages

This nine-piece hex key set offers a concise range of metric sizes to match typical small- to medium-diameter hex fasteners. The L-shape provides a long arm for reach and a short arm for torque, enabling both clearance access and higher turning force when needed. The compact set is easy to store and transport, and its stepped size progression simplifies choosing the correct key. The tools are suitable for repeated use in assembly and maintenance environments.

How to use

Select the hex key that fits snugly into the hex socket of the fastener to avoid rounding. Use the short arm when greater torque is required and the long arm when extra reach or leverage is needed. Insert the key fully and turn steadily; avoid excessive force that could damage the fastener head. For repeated fastening tasks, work methodically through the fasteners in sequence to ensure uniform tension.

Usage recommendations

Store the set in a dry place and keep keys organized to prevent loss. For painted or delicate surfaces, protect contact areas to avoid scratches. Inspect key tips periodically for wear and replace any deformed keys to maintain safe operation.
