Extended Reach Impact Folding Hex Key Set, SAE

Access deep-set fasteners and recessed electrical panel lugs with ease using the Klein Tools 70550HD Extended Reach Impact Folding Hex Key Set. Engineered specifically for professional electricians and industrial tradespeople, this heavy-duty SAE set features 11 hex sizes—ranging up to a massive 1/2-inch. Built with square-cut hex tips for full-depth engagement, each key folds independently up to 270 degrees to deliver optimal leverage in cramped enclosures. The integrated barrel features a 1/4-inch impact-rated quick-connect, allowing smooth integration with flip sockets, nut drivers, and impact accessories, while Klein's high-visibility color-coding system ensures swift size identification on busy job sites.

Key Features:

• Extended Reach Hex Blades: Elongated profile reaches deep into distribution panels, disconnects, and motor housings where standard folding keys fall short.

• Comprehensive 11-Piece SAE Range: Covers essential fractional sizes up to 1/2-inch for heavy-duty commercial electrical installations.

• 270-Degree Key Rotation: Individual keys pivot up to 270 degrees, functioning as straight-drive keys or high-torque L-handles depending on clearance.

• Integrated 1/4" Impact Quick-Connect: Built-in connector accommodates 1/4-inch impact accessories, modular flip sockets, and magnetic nut drivers.

• Klein Tools Color-Coding: Distinct color bands provide instantaneous size recognition, saving time and preventing misfits.

• Square-Cut Precision Tips: Clean square-cut ends seat fully into fastener sockets to eliminate slippage and prevent rounded hex bolts.

• Rugged Heavy-Duty Housing: Durable composite and steel chassis stands up to job-site drops, grease, and high-torque demands.
