Wiha 369ZB L-shaped Hex Key Set, Imperial, 13 Pieces

The Wiha 369ZB L-shaped Hex Key Set is a professional-grade tool collection designed for precision and reliability in mechanical and assembly environments. This 13-piece set features imperial sizing, making it an essential addition for technicians and DIY enthusiasts working with inch-based fasteners. Each key is engineered for durability and high-torque performance, ensuring that even the most demanding fastening tasks are completed with ease.

Advantages

The primary benefit of this set lies in its high-quality construction using through-hardened chrome-vanadium steel, which provides exceptional strength and resistance to wear. The bronzed surface finish offers added protection against corrosion, extending the lifespan of the tools. Furthermore, the inclusion of the space-saving ProStar holder allows for the individual removal of each key without the need to displace others, significantly improving workflow efficiency and organization in the workspace.

Suitable for

• Mechanical assembly and maintenance tasks
• Working with inch-sized screws in confined spaces
• Industrial equipment repair
• Professional workshop applications
• DIY home improvement projects

When it may not be suitable

This set is specifically designed for imperial-sized fasteners and will not be compatible with metric-sized screws. Using these keys on metric hardware may result in damage to both the tool and the fastener head.

Key specifications

• Material: Through-hardened chrome-vanadium steel
• Finish: Bronzed surface
• Standard: Based on ASME B18.3
• Quantity: 13 pieces
• Measurement system: Imperial
• Storage: ProStar holder

How to use

To use the hex keys, simply select the required size from the ProStar holder by rotating the individual key slot. Insert the long or short end of the L-shaped key into the screw head, ensuring a secure fit. Apply steady pressure to turn the fastener. The L-shape design provides leverage, allowing for effective torque application even in restricted areas where access is limited.

What to consider before purchase

• Verify that your equipment requires imperial (inch) sizing rather than metric.
• Ensure the range of sizes included meets your specific project requirements.
• Consider the workspace environment to ensure the L-shaped design provides sufficient clearance.

Usage recommendations

Always ensure the hex key is fully seated in the screw head before applying torque to prevent slipping or stripping the fastener. Store the keys in the provided ProStar holder after use to maintain organization and prevent loss.
