Hex key Proline 48558 — 1 pc, L-shaped Allen wrench

Proline 48558 is a single-piece L-shaped hex key designed for manual tightening and loosening of hex (Allen) fasteners. Supplied as one compact unit, this hex key is intended for workshop, maintenance and assembly tasks where a simple, reliable hand tool is required. The L-shape provides leverage for torque application and a short arm for access in confined spaces.

Advantages

The Proline L-shaped Allen wrench offers a straightforward, durable design that simplifies work with internal hex fasteners. Its single-piece construction reduces the risk of loosening or misalignment during use, and the compact form factor enables access to tight spaces where longer tools cannot reach. The L-shape allows users to choose between torque (long arm) and maneuverability (short arm) depending on the task.

Suitable for

• General workshop tasks involving hex-head fasteners
• Furniture assembly and disassembly
• Routine maintenance and repair of machinery or equipment with Allen screws
• Work in confined or hard-to-reach areas

Key specifications

• Tool type: L-shaped hex key (Allen wrench)
• Supply: single piece (1 pc)
• Drive style: internal hex
• Form factor: L-shaped for two-handed leverage options
• Typical use: manual tightening and loosening of hex fasteners

How to use

Select the hex key size that fits the hex socket of the fastener securely. Insert the short or long arm into the screw head according to the required torque and clearance: use the long arm for greater torque and the short arm for limited access or faster turning. Turn the tool clockwise to tighten and counterclockwise to loosen, maintaining firm, even pressure to avoid rounding the fastener. Inspect the wrench and fastener before use to ensure a snug fit and safe operation.

Usage recommendations

Use the Proline L-shaped hex key in dry, clean conditions and avoid excessive force beyond manual torque limits. For stubborn or corroded fasteners, consider applying penetrating lubricant and use appropriate safety equipment. Store the tool in a toolbox or rack to keep the working tip clean and to prevent damage.
