Compact Nine-Key Hex Set
The Klein Tools 409-70591 folding hex nutdriver combines nine imperial hex keys in a single pocket-sized handle. Technicians, electricians and DIY users who carry a tool pouch gain immediate access to sizes from 5/64-Inch through 1/4-Inch without hunting for loose bits. The folding design keeps every key captive and ready for fasteners on electrical enclosures, machinery or automotive work.
Dual-Angle Leverage
Each key locks at two positions: straight-out for reach and right-angle for extra torque. Square-cut tips seat fully in hex sockets, reducing cam-out and protecting both the fastener and the tool from stripping. The pivot mechanism holds the selected key firmly so it does not fold back under load during tightening or loosening.
Pocket-Ready Durability
The reinforced handle withstands daily job-site use and resists cracking when dropped. A stainless steel pocket clip secures the set to a belt, bag or toolbox edge so it stays visible and within reach. No separate case or organiser is required, eliminating the common problem of misplaced individual hex keys.

Questions about this item
Do any of the nine hex keys wear out and need replacing?
The hex ends are square-cut for full-depth contact, which reduces rounding and stripping so the keys last longer under normal use.
Which key size will reach its torque limit first during heavy use?
The smallest 5/64-inch key has the least cross-section, so it will hit its torque limit before the larger sizes.
Does the folding handle get hot or slippery after hours of continuous turning?
The handle is designed for hand torque only; it does not generate heat and the folding design maintains grip during extended use.
