Hex key Proline 48570 — 6 mm metric hex wrench, single piece

Proline 48570 is a single-piece 6 mm metric hex key designed for tightening and loosening hex socket fasteners. Made from quenched and tempered steel with a polished chromium finish, the tool offers a compact profile and solid contact with 6 mm hex drives. It is intended for use in assembly, maintenance and repair tasks where a single, durable hex wrench is required.

Advantages

The single-piece construction provides consistent torsional strength and reduces the risk of bending under typical workshop loads. The quenched and tempered steel core improves hardness and wear resistance, while the polished chromium finish protects against surface corrosion and facilitates cleaning. Its compact size allows access to confined spaces and offers precise torque delivery to 6 mm fasteners.

Suitable for

• Tightening and loosening M6 hex socket bolts and screws
• General workshop assembly and maintenance
• Home DIY repairs and furniture assembly
• Light construction and mechanical servicing tasks

Key specifications

• Tool type: single-piece metric hex key (Allen wrench)
• Size: 6 mm hex drive
• Material treatment: quenched and tempered steel
• Surface finish: polished chromium
• Design: straight L-shaped profile for torque and reach

How to use

Insert the 6 mm hex end fully into the fastener's socket to ensure full contact and reduce rounding. Apply steady, even force when turning; use the long arm for greater leverage and the short arm for access in tight spaces. After use, wipe the tool clean and store it in a dry place to preserve the polished chromium finish and prevent corrosion.

Usage recommendations

Use the correct 6 mm hex engagement to avoid damage to fastener heads. Do not apply impact loads or use the tool as a pry bar. For tasks requiring higher torque, consider using the long arm or a different tool designed for high-torque applications.
