Hex Key Set Wiha 352H11 — 11-piece hex key set, L-shaped tools for metric hex screws

Wiha 352H11 is an 11-piece hex key set designed to drive metric hex screws. The set contains L-shaped hex keys in a range of common metric sizes, supplied in a compact holder that keeps each key organized and easily accessible. The tools are manufactured by wiha to provide consistent geometry for reliable fit into hex fasteners and to withstand normal workshop, assembly and maintenance use.

Advantages

The L-shaped design gives good leverage for tightening and loosening hex screws while the compact storage holder keeps keys neatly aligned and portable. Hardened, precision-formed tips reduce rounding of fasteners and ensure repeatable engagement. The set covers a practical range of metric sizes for general mechanical and electrical work, and the individual keys are long enough to reach recessed hex sockets while retaining hand clearance.

Suitable for

• Assembly and disassembly of furniture, machinery and equipment
• Maintenance and repair tasks in workshops and service departments
• Electrical and mechanical installations using metric hex fasteners
• DIY projects and hobby work requiring reliable hex tools

Key specifications

• Number of pieces: 11 hex keys
• Tool shape: L-shaped (short arm and long arm)
• Sizes: full metric range covering small to medium hex fasteners (common workshop sizes)
• Material/finish: hardened steel with precision-formed tips
• Storage: compact holder for organized storage and quick access
• Intended use: driving metric hex screws and bolts

How to use

Select the hex key that fits snugly into the hex socket of the fastener. Insert the short or long arm as the working end depending on required torque and reach: use the long arm for access to recessed fasteners and the short arm when higher torque is needed. Apply steady force in the correct turning direction, keeping the key fully seated to avoid cam-out or rounding. After use, return each key to its designated slot in the holder to maintain organization and reduce loss.

Usage recommendations

Use the correct key size for each fastener to prevent damage. Do not use cheater bars or apply excessive impact force; if a fastener is seized, apply penetrating lubricant and work progressively. Store the set in its holder and keep away from corrosive environments to prolong service life.
