Online Lee Valley Imperial & Metric Hex Key Sets

Hex keys have a tendency to scatter in toolboxes, with the size you need inevitably the one that’s hardest to find. A set kept together by a case can save you a lot of frustration. These hex keys have good reach (ranging from 4 1/4″ to 6 3/4″ long, proportional to size) and a ball-end that lets you use them at an angle to access fasteners in tight spaces.

Made of S2 tool steel, they are tough and reliable. The two sets include the most commonly used sizes: Imperial in 0.05″, 1/16″, 5/64″, 3/32″, 7/64″, 1/8″, 9/64″, 5/32″, 3/16″, 7/32″, 1/4″, 5/16″ and 3/8″, and metric in 1.5mm, 2mm, 2.5mm, 3mm, 4mm, 5mm, 6mm, 8mm and 10mm. And, of course, both sets are supplied in a sturdy plastic case.
