Hex key Proline 48441 — 1.5 mm metric hex key, 1 pc

Proline 48441 is a single-piece metric hex key with a 1.5 mm tip designed for working with hexagonal socket screws in electronics, small appliances and precision assemblies. The tool is quenched and tempered for strength and finished with polished chromium for corrosion resistance and smooth handling. Its compact single-piece construction provides a precise fit in small fasteners and allows access in tight spaces where larger wrenches cannot reach.

Advantages

This 1.5 mm hex key offers a precise tip geometry that reduces cam-out and improves torque transfer to small socket screws. The quenched and tempered heat treatment increases durability and resistance to bending, while the polished chromium finish enhances surface protection and eases cleaning. Being a single compact piece, the key is easy to store and carry, and its standardized metric size ensures compatibility with common small hex fasteners.

Suitable for

• Assembly and disassembly of electronic devices and PCBs
• Repair and maintenance of small appliances and household gadgets
• Precision mechanical assemblies and instrumentation
• Hobbyist and DIY projects requiring small metric hex tools

Key specifications

• Tip size: 1.5 mm metric
• Quantity: 1 piece
• Material treatment: quenched and tempered for increased hardness
• Surface finish: polished chromium for corrosion resistance
• Design: single-piece L-shaped hex key for access in confined spaces

How to use

Select the 1.5 mm tip for hexagonal socket screws that match the metric size. Insert the short or long arm into the screw socket depending on reach and torque requirements: use the long arm for reach and the short arm for higher torque. Apply steady, controlled force to avoid stripping the screw head. After use, wipe the tool clean to remove debris and moisture and store it in a suitable toolbox or organizer to maintain the polished chromium finish.

Usage recommendations

For best results, use the Proline 1.5 mm hex key on screws specifically sized for 1.5 mm tools; avoid applying excessive force beyond the tool’s capacity to prevent deformation. Keep the polished chromium surface dry and lightly oiled if stored in humid environments to reduce corrosion risk.
