Best Hex & Allen Key Sets for DIYers
Hex (Allen) keys drive the recessed bolts on furniture, bikes, appliances, and countless products. A good metric-and-SAE set with ball ends and a comfortable holder saves stripped fasteners and lost keys.
What to look for
- ·Get both metric and SAE (inch) sets, since products use one or the other; ball-end keys let you reach bolts at an angle.
- ·Quality steel resists rounding off the tips. A folding set or a holder keeps the keys together and sized.
- ·For frequent use, hex bits for a driver or a T-handle set speed things up over plain L-keys.

Frequently asked
What hex key sizes do I need?+
Get a set in both metric (mm) and SAE (inch) sizes, since furniture, bikes, and tools vary. Common sizes range from about 1.5mm to 10mm and 1/16 to 3/8 inch. A combined set covers nearly everything you will encounter.
What are ball-end hex keys?+
Ball-end keys have a rounded tip that lets you insert and turn the bolt at an angle (up to about 25 degrees off-axis), which is handy in tight spots. Use the straight end for final tightening and breaking loose, since the ball end has less grip under high torque.
L-keys, folding set, or T-handle?+
L-shaped keys are cheapest and most portable. A folding set keeps them together like a pocketknife. T-handle keys give the most comfort and speed for frequent use. For assembling furniture occasionally, an L-key or folding set is plenty.
Why do my hex keys round out bolts?+
Usually a worn or wrong-size key, or a cheap soft key. Use the exact size (metric vs SAE matters), seat it fully, and use a quality hardened key. For a rounded bolt, a slightly larger key or a bolt extractor may grab it.
Can I use hex keys in a drill?+
Use hex bits (not L-keys) in a drill or impact driver for power driving, which is much faster for repetitive assembly. Many sets include both keys and driver bits. For delicate or final-torque work, hand-tighten so you do not strip or over-tighten.
