Pro Folding Hex Key Set 11 Piece

This Klein Tools set consolidates two hex key sets into one 11-piece folder. It covers fractional inch sizes from 3/32 to 1/2 inch for common fastening tasks. The reinforced nylon handle provides a comfortable grip during extended use. Industrial-grade construction suits demanding job-site conditions.

Eleven extended-reach blades range from approximately 3.5 to 4.5 inches long. The high-leverage 1/2-inch key measures 4 inches for extra torque on stubborn fasteners. Blades open independently up to 270 degrees for access in tight spaces. Square-cut ends deliver full-depth socket contact to prevent slippage and stripping.

Thermals noise and power draw

Hand-operated design produces no heat, noise or electrical draw during normal use. Heat-treated alloy steel blades resist wear under heavy torque loads.
