Hex key Proline 10 mm, model 48526, single piece

Proline 10 mm hex key model 48526 is a single-piece metric Allen key designed for manual tightening and loosening of 10 mm internal-hex bolts and screws. Supplied as one durable tool, it is intended for general assembly, maintenance and repair tasks where a compact, reliable hex driver is required. The tool's straightforward single-piece construction offers a fixed working length and a consistent fit for 10 mm fasteners.

Advantages

The single-piece design provides solidity and a predictable working angle without moving parts, reducing the risk of deformation under typical hand-torque. Manufactured to fit 10 mm hex recesses, the key ensures accurate contact with fastener walls to minimise rounding. Its compact size makes it easy to store or carry in a toolbox, drawer or pocket, and the simple geometry enables use in confined spaces where larger tools would not fit.

Suitable for

• Workshop assembly and light mechanical repairs
• Automotive maintenance tasks involving 10 mm hex fasteners
• Household repairs and furniture assembly with 10 mm internal-hex screws
• Hobby and DIY projects requiring a reliable 10 mm hex driver

Key specifications

• Tool type: single-piece metric hex key (Allen key)
• Size: 10 mm hex profile
• Quantity: single piece
• Intended use: manual operation for tightening/loosening hex fasteners
• Suitable environments: workshop, automotive, household

How to use

Insert the 10 mm end of the hex key fully into the internal hex recess of the fastener to ensure full contact with the fastener walls. Apply steady manual torque in the required direction to tighten or loosen the bolt or screw. For best control, use the longer arm of the key for higher leverage and the shorter arm for access in confined spaces. Inspect the key and the fastener for wear before use and avoid applying excessive force beyond hand torque to prevent tool or fastener damage.

Usage recommendations

Use the Proline 10 mm hex key for tasks within its manual torque limits and keep it clean and dry to prevent corrosion. Store the key in a designated slot in a toolbox or on a tool rail to maintain condition and ease of access. For stubborn or heavily torqued fasteners, consider using a tool specifically designed for higher torque or impact use rather than forcing a single-piece hand hex key.
