## Long description

Proline hex key 3 mm (model 48528) is a single-piece metric Allen key designed for tightening and loosening hex-socket fasteners with a 3 mm size. Manufactured for general assembly and maintenance, this compact tool fits into confined spaces and provides a straightforward solution for tasks that require a 3 mm hex driver. Supplied as one unit, it is suitable for occasional household use as well as for professional service tasks that call for a basic, reliable hex key.
Advantages
This 3 mm hex key offers a simple, durable design that minimizes flex during use and ensures consistent engagement with hex fasteners. Its single-piece construction reduces the risk of joint failure and simplifies storage and transport. The standard metric sizing guarantees compatibility with common 3 mm hex-socket bolts and screws used in furniture, bicycles and light machinery.

Key specifications
 Tool type: Hex key (Allen key)
 Size: 3 mm (metric)
 Quantity: 1 piece
 Construction: Single-piece solid hex bar
 Finish: raw or black-oxide style surface suitable for grip and corrosion resistance
 Intended use: manual operation for tightening and loosening hex-socket fasteners
How to use
Insert the 3 mm end of the hex key fully into the hex socket of the fastener to ensure a secure fit before applying torque. Turn clockwise to tighten and counterclockwise to loosen, using steady, controlled force to avoid stripping the fastener head. For greater leverage, use the long arm of the L-shaped key; for access in tight spaces, use the short arm. Inspect the tool and the fastener head for wear before use and avoid applying excessive force that could damage either component.
Usage recommendations
Use the 3 mm hex key for fasteners matched to the 3 mm metric size and apply moderate torque appropriate to the fastener material. Keep the tool clean and dry and store it in a tool roll or box to reduce corrosion and maintain dimensional accuracy. For frequent or high-torque applications, consider using a tool with a ball-end or longer leverage option designed for repeated professional use.
