## Long description

The Proline 3 mm hex key is a single, metric Allen key designed for driving hex socket screws and bolts.

Key specifications
Tool type: single L-shaped hex key (Allen key)
Size: 3 mm (metric)
Material: quenched and tempered steel
Surface finish: polished chromium
Design: one-piece, solid construction
Weight: compact and lightweight for easy portability
How to use
Select the 3 mm end that matches the hex socket of the screw or bolt. Insert the short or long arm into the socket to obtain the required leverage and turn clockwise to tighten or counterclockwise to loosen. Ensure full seating of the key in the fastener before applying torque to avoid rounding the socket. For higher torque needs, use the long arm as a lever; for confined spaces, use the short arm.
Usage recommendations
Inspect the hex key and fastener for damage before use. Store in a dry place to maintain the polished chromium finish and prevent corrosion. Avoid using excessive force beyond the tool's size rating to prevent deformation of the key or damage to the fastener.
