ISO 2936 Hex Key

ISO 2936 Hex Keys are "L" shaped keys that are used to tighten and loosen internally wrenched fasteners like socket set screws, socket head cap screws and socket shoulder bolts. They are available in short (standard) and long arm versions. The length of the short leg (bottom of the "L") is the same for short and long arm keys of the same size—only the long leg differs. The length of both legs increases as the key size increases. Long arm hex keys are used to drive screws in deep recesses and, when the long leg is used as the lever, higher torque values can be achieved. A single hex key will often fit several different screw sizes—a 3 mm hex key, for example, is used with M4 socket head cap screws; M5 button, flat and low head socket cap screws; and M6 socket set screws and socket shoulder bolts. All keys are plain finish (not plated). Also known as hex socket keys, hexagon socket screw keys, hex wrenches and Allen keys, sizes 0.7 through 8 mm have a Rockwell hardness of 52 HRC, 9 through 14 mm are 48 HRC and 15 through 36 mm are 45 HRC. Key size is specified as the width across parallel sides (flats). Since hex keys aren't threaded, their size is correctly designated in mm (millimeters), such as 4 mm, but it is common to see "mm" omitted and their size preceded by the letter "M" (which denotes metric screw thread), as in M4. To avoid confusion, we reluctantly follow that practice.

  • Click in a Select box to view the options. It may be necessary to scroll to see the entire list. The number of matching items is displayed in parentheses ( ).
  • Click on the desired item and -- Select -- will change to 1 Selected. You can select more than one item in each Select box. For example, you can select two sizes and 1 Selected will change to 2 Selected.
  • Click in other Select boxes and make more choices. Available options will be based on selections you've already made.
  • Even though there are thousands of fasteners to choose from a particular material or finish may not be available in every size and length. So, try different combinations of filters like Size, Grade and Material to see matching Lengths and Finishes.
  • To deselect a single filter option, click in the Select box and click on the selected option. It will appear at the top of the list in bold. To clear all filter selections, click on the Clear Filters button.
