Coofix Allen key

The Coofix Allen Key (also called a hex key or Allen wrench) is a simple hand tool shaped like an “L” with a hexagonal (six-sided) cross-section. It is designed to fit into the hexagonal recesses of bolts and screws commonly used in furniture, machinery, bicycles, and equipment assembly.

Coofix produces a range of Allen keys under various model codes as part of its hand-tool range. The keys are typically sold individually or in sets covering multiple sizes.

Key Features

• Brand: Coofix

• Tool Type: Allen key / Hex key / Hex wrench

• Material: Hardened steel (often chrome-vanadium or similar alloy) for strength and long life

• Finish: May have black oxide or chrome plating for corrosion resistance

• Shape: Classic L-shaped for leverage — the long arm gives reach, the short arm gives torque

• Sizes: Available in metric sizes such as 1.5 mm, 2 mm, 2.5 mm, 3 mm, 4 mm, 5 mm, 6 mm, 8 mm, 10 mm, etc.

• Set or Individual: Sold as individual keys or multi-piece sets in a holder or pouch

How It Works

A Coofix Allen key is used by inserting the hex end into a hexagonal (Allen) screw head — then turning it to tighten or loosen the screw or bolt. The L-shape offers two torque options:

• Short arm in screw: More torque for stubborn fasteners

• Long arm in screw: Better reach and speed for regular fastening

Common Uses

Coofix Allen keys are ideal for:
✔ Assembly of flat-pack furniture (beds, tables, shelves)
✔ Bicycle maintenance (handlebars, seat posts)
✔ Automotive and machine work
✔ Electronics and device repair
✔ General workshop use
