## Long description

Proline 48320 — single-piece Allen wrench is a compact, single-size hex key designed for manual tightening and loosening of hex-socket fasteners.

It is available in multiple sizes to match standard hex bolt and screw dimensions, making it suitable for a variety of small assembly and repair tasks in workshops and at home.
Advantages

A covered handle increases grip security and reduces hand fatigue during prolonged use. The precisely machined hex tip ensures a snug fit in hex sockets, which minimizes rounding of fastener heads and improves turning accuracy.

How to use
Select the hex key size that matches the hex socket of the fastener. Insert the short or long end of the key into the hex recess so that the contact surfaces engage fully. Apply steady hand force to turn the wrench clockwise to tighten or counterclockwise to loosen. Use the covered handle to maintain a secure grip and control torque; avoid excessive force that could strip the fastener or deform the tool.
Usage recommendations
For reliable performance, keep the hex tip clean and free of debris, choose the correct size to avoid rounding fasteners, and store the wrench dry to prevent corrosion. Use the larger sizes for higher torque applications and the smaller sizes for precision or confined-space work.
