Hex key Proline 5 mm — 1 pc (model 48488)

The Proline 5 mm hex key (single piece) is an L-shaped metric wrench designed for tightening and loosening hex socket fasteners. Made from quenched and tempered steel with a polished chromium finish, this compact tool provides a corrosion-resistant surface and a smooth feel during use. Supplied as a single 5 mm size, it is intended for tasks where a dedicated hex key is required, offering a simple and durable solution for workshop, home and professional applications.

Advantages

The heat-treated construction increases strength and wear resistance, while the polished chromium finish helps protect against rust and simplifies cleaning. Its L-shape offers good torque leverage and access to recessed fasteners. Being a single-piece tool, it is lightweight, easy to store, and reduces clutter when only one size is needed.

Suitable for

• Tightening and loosening hex socket screws in furniture assembly
• Maintenance tasks on machinery and equipment
• Home repairs and DIY projects requiring a 5 mm hex key
• Workshop use where a durable single-size wrench is sufficient

Key specifications

• Tool type: L-shaped hex key (Allen key)
• Size: 5 mm (metric)
• Quantity: 1 piece
• Material treatment: quenched and tempered steel
• Finish: polished chromium
• Design: single-size, fixed-length L-wrench for manual use

How to use

Insert the short or long arm of the hex key into the hex socket of the fastener, depending on required reach and leverage. Turn the tool clockwise to tighten and counterclockwise to loosen. Apply steady, even force to avoid rounding the fastener head; for higher torque, use the long arm for leverage and the short arm to reach confined spaces. After use, wipe the tool clean and store it in a dry place to preserve the polished chromium finish.

Usage recommendations

Use the Proline 5 mm hex key only on appropriately sized hex sockets to prevent damage to fasteners. Avoid using the tool as a pry bar or hammer. For repetitive or high-torque industrial applications, consider using tools or adapters designed for higher torque or impact-rated use to prolong tool life.
