Klein Tools 70542 Folding Hex Key Set — 17 Keys (SAE & Metric), 2-Pack

Portable precision for professionals and DIYers

The Klein Tools 70542 Folding Hex Key Set combines two compact kits into a pocket-friendly solution. With 17 keys—nine SAE sizes and eight metric sizes—you have rapid access to common fasteners at the workspace, in the shop, or on the road. The design centers on practical performance: keys fold into a rugged case, and the sizes are chosen to cover daily tasks without carrying a bulky toolbox.

Built for secure, long-lasting use

Each hex blade features square-cut ends for a full-depth contact with sockets, helping reduce slippage and socket wear. The blades are heat-treated alloy steel and coated to resist rust, so they stand up to daily use in varied environments. The blades range from 2.25 to 2.5 inches, balancing reach with control.

• 270-degree range: each blade opens independently for work at all angles, from tight corners to open panels.
• COMPACT DESIGN: pocket-sized and easy to store when not in use.
• HEAVY-DUTY NYLON HANDLE: reinforced casing provides a comfortable, secure grip during longer tasks.
• Easy KEY ACCESS: side openings in the case ensure quick access to outer keys for fast swaps.

Versatile in real-world tasks

Ideal for assembling and maintaining appliances, bikes, equipment, or electronics with hex fasteners. The 2-pack setup gives you the option to keep one kit in your van and another in your workshop, or to share one set with a teammate.

• Durable construction supports repeated use in demanding environments.
• Clear size coverage helps you identify the right key quickly, reducing downtime.
