Hex Key Proline 48527 — hex key 2.5 mm, single piece

Proline 48527 is a single-piece metric hex key with a 2.5 mm tip designed for tightening and loosening hex-head fasteners. The compact, single-bit format provides a straightforward solution for tasks that require only one size of allen key, making it suitable for maintenance, repair and light assembly work in mechanical and electronics applications.

Advantages

The single-piece construction offers rigidity and direct torque transfer to the 2.5 mm hex tip. Its compact length and simple design allow easy access to confined spaces and clear visual identification of the required size. Made to fit standard 2.5 mm hex fasteners, the tool reduces the need to carry a full set when only one size is needed.

Suitable for

• Tightening and loosening 2.5 mm hex bolts and screws
• Electronics assembly and repair where compact tools are required
• Furniture assembly and small appliance maintenance
• General DIY and routine maintenance tasks

Key specifications

• Tool type: single-piece metric hex key (allen key)
• Tip size: 2.5 mm
• Material: hardened steel (typical for this tool type)
• Finish: corrosion-resistant surface treatment (typical for hand tools)
• Design: straight single-bit form for direct torque application

How to use

Insert the 2.5 mm hex tip fully into the hex recess of the fastener to ensure proper engagement. Apply steady turning force in the appropriate direction to tighten or loosen the screw or bolt; avoid sudden, excessive force to prevent rounding the fastener. When working in tight spaces, use the short end for higher torque and the long end for reach if the tool length allows.

Usage recommendations

Inspect the hex tip before use for wear or damage and replace the tool if the edges are rounded. Use the correct size—2.5 mm—to avoid damaging fasteners. Store the hex key in a dry place to limit corrosion and keep it with other commonly used tools for easy access during maintenance or repair tasks.
