Hex Key Wrench

Hex keys, also known as Allen keys or Allen wrenches, are a vital tool for mechanics, engineers, and machinists working with hex fasteners. These L-shaped bars allow torquing bolts, screws, and other fasteners in hard-to-reach spots and tight quarters where bulky wrenches are unusable. With a versatile and compact design, hex keys provide efficient access and usability across limitless applications.

What is a Hex Key?

Hex keys consist of a short L-shaped metal bar with a hexagonal shaft on the long arm that engages with hexagonal socket screws and bolts. The short arm provides improved leverage and access for generating torsion and driving the fastener. The most common size range is from .028" across flats up to 3/8", covering imperial and metric fasteners. Long-arm versions give even greater reach.
