Wera Tool-Check Modular L-keys Hex-Plus 1 set, 7 pezzi (05049003001)

Wera Tool-Check Modular 1.7-piece Hex-Plus is a compact hex key set engineered for internal hex fasteners using Wera's Hex-Plus profile. The set groups multiple hex keys in a modular holder that keeps tools organized and accessible for workshop and on-site use. Designed to reduce wear on fastener corners, it provides efficient torque transfer and consistent fit across a range of maintenance and assembly tasks.

Advantages

The Hex-Plus profile minimizes rounding of hex fasteners and improves contact surface between key and screw for better torque application. The modular holder secures individual keys, simplifies transport, and enables quick size selection. Robust material and precision machining ensure durability, while compact dimensions save space in toolkits and pockets.

Suitable for

• Assembly and disassembly of machines and equipment with internal hex fasteners
• Maintenance tasks in workshops, service vehicles, and on-site repairs
• Precision mechanical work where reducing fastener wear is important
• Compact toolkits for technicians, engineers, and hobbyists

Key specifications

• Hex-Plus profile for reduced fastener rounding and improved torque transfer
• Modular holder design holding multiple hex keys securely
• Set composed of a range of metric hex key sizes supplied in a single compact unit
• Precision-machined keys for consistent fit and reliable operation
• Durable construction suited for repeated workshop and field use

How to use

Select the correct hex key size from the modular holder and swing or remove the key as required for access. Insert the hex key fully into the fastener recess to ensure maximum contact with the Hex-Plus profile before applying torque. Use steady, controlled force to tighten or loosen fasteners, and return the key to the holder after use to maintain organization and protect the tools.

Recommendations

Inspect fastener recesses for debris and select the Hex-Plus key size that fits without play. Avoid using damaged or excessively worn keys and clean or lubricate fasteners when needed to reduce friction. Store the modular unit in a dry place to prevent corrosion and maintain the precision fit of the keys.
