9-Key Folding Hex Key Set - SAE

The Milwaukee 9-Key SAE Folding Hex Key Set (48-22-2181) puts nine of the most-used SAE hex sizes in one compact folding tool, with an elevated key shelf and access zones that lift each key for fast selection. This is the complete set — no batteries or accessories required.

What it does well

• Full metal body construction built to withstand high torque and hold up in demanding jobsite conditions
• Keys rotate up to 270° for better access and torque in tight spaces
• Heat-treated alloy steel keys with a black oxide finish that resists rust and corrosion
• High-contrast, color-coded handle markings make it easy to identify the right key size, with chamfered key ends for easier insertion into fasteners

Is this the right hex key set for you?

If you work in SAE fasteners and want a pocket- or pouch-friendly folding set rather than loose keys, this covers the common range from 5/64" to 1/4". The ergonomic handle and elevated key shelf make it a good pick for repetitive work where quick key selection matters. If your fasteners are metric, choose a metric set instead.
