PARK TOOL PROFESSIONAL ALLEN KEY SET HXS-1.2 1.5-10MM

The Park Tool HXS-1.2 is a shop-quality professional L-shaped Allen key set that brings together virtually every hex size found on a bicycle. With the Park Tool HXS-1.2 Allen key set you can adjust, remove and install stems, handlebars, levers, derailleurs, brakes, pedals, crank bolts, bottle cages and almost any other component with a recessed hex fitting.

The set includes nine keys: 1.5, 2, 2.5, 3, 4, 5, 6, 8 and 10 mm. Each key has two ends designed for different tasks. The long arm ends in a ball end, which lets you work with the key at an angle and reach bolts in awkward positions; the 10 mm key is the only one without a ball end. The short arm has a straight tip, to be used when high torque is needed with maximum contact. The tips are precision-chamfered to enter the socket cleanly and work without play, reducing the risk of rounding the bolt hex. The industrial-quality steel is through-hardened, meaning hardened through its full thickness rather than just on the surface, for durability designed to last a lifetime. The keys come in a handy portable holder, easy to keep on the bench or hang on the tool board.
