HARFINGTON 20-Pack 3mm Hex Key Wrench – L-Shaped CR-V Steel, Black Oxide Finish, Heat-Treated For Furniture & Equipment Assembly

About This Product

If you've ever lost a tiny allen key right in the middle of assembling furniture or fixing a door handle, you know the pain.

This 20-pack of 3mm hex keys means you'll have spares for days – no more crawling around on the floor looking for that one little L-shaped wrench that rolled under the couch.

These are made from CR-V steel that's been quenched and heat-treated to 55-58 HRC, so they're tough enough to handle serious torque without bending or rounding off.

The black-oxide finish helps resist rust and wear, so they stay looking decent even after repeated use.

Each key measures about 2.

5 inches total length – the classic L-shape with a short arm and a long arm gives you leverage when you need it and reach when you're in tight spots.
The head is chamfered too, which helps it slide smoothly into the fastener and reduces wear on both the key and the screw head – smart engineering that makes a real difference over time.

These work great for towel bars, door handles, furniture assembly, bike repairs, and all kinds of small equipment.
Just double-check that you need 3mm before you buy – if you're working with metric fasteners, this is a common size you'll use again and again.
