Hex key Proline 8 mm — Proline 48532 single hex key (metric)

Proline 8 mm hex key (single metric) is a compact hand tool designed for driving hex-head fasteners and screws with an 8 mm internal hex profile. The single-piece design provides a straightforward solution when a specific-sized wrench is required for maintenance, assembly or repair tasks. Its size and shape make it suitable for use in confined spaces and for applications where portability and simplicity are priorities.

Advantages

The solid construction offers torque transmission with minimal flex, while the metric 8 mm head ensures compatibility with standard hex fasteners. As a single hex key, it is lightweight and easy to store, reducing clutter in toolkits and pockets. The tool's finish resists corrosion during normal use and helps maintain a reliable contact surface with fasteners.

Suitable for

• General maintenance and repair of machinery and equipment
• Furniture assembly and tightening of hex-head fittings
• On-site service work where a single-size hex key is needed
• Workshop tasks that require access in narrow or recessed areas

Key specifications

• Hex size: 8 mm (metric internal hex profile)
• Type: single-piece L-shaped hex key
• Material: hardened steel for strength and wear resistance
• Finish: corrosion-resistant surface treatment
• Usage: manual operation for driving hex fasteners and screws

How to use

Select the 8 mm hex key and insert the short or long arm into the hex socket of the fastener, depending on required leverage and clearance. Apply steady torque while keeping the tool aligned with the fastener to avoid rounding. For loosening, turn counterclockwise; for tightening, turn clockwise. Use the long arm for higher torque and the short arm for access in tight spaces.

Usage recommendations

Inspect the hex key and the fastener before use to ensure correct fit and to prevent damage. Apply controlled force and avoid using cheater bars or extensions. Store the tool in a dry place and keep it clean to prolong service life.
