Hex key Proline 48502 — 1 pc

The Proline 48502 single hex key is a compact hand tool designed for driving hex-head fasteners with a single fixed size. Made from quenched and tempered steel and finished with polished chromium, this hex key offers a simple, durable solution for assembly, maintenance and repair tasks. Its compact form factor makes it easy to carry in a toolbox or pocket and convenient for use in workshops, garages and on-site jobs where a straightforward Allen/hex key is required.

Advantages

The hardened construction from quenched and tempered steel provides strength and wear resistance while the polished chromium finish helps protect the surface against corrosion and reduces friction in the socket. As a single-piece tool, it eliminates moving parts and offers immediate readiness for use. The compact size and solid build make it suitable for repeated tightening and loosening of hex screws without deformation.

Suitable for

• Assembly of furniture and fittings
• Routine maintenance of machinery and equipment
• Repair tasks on bicycles, appliances and electronics
• Workshop and professional service use where a single-size hex key is required

Key specifications

How to use

Select the hex key size that matches the hex socket of the fastener and insert the short or long end into the screw head as appropriate for access and leverage. Apply steady turning force in the required direction to tighten or loosen the fastener. Use the long arm for greater torque and the short arm for confined spaces. After use, wipe the tool clean and store it in a dry place to maintain the chromium finish.

Usage recommendations

For best results, avoid using the hex key on rounded or damaged fasteners; if significant resistance is encountered, inspect the screw head and consider using a correct-sized replacement or a professional repair method to prevent tool or fastener damage.
