A hex key is an L-shaped tool with a hexagonal cross-section, to loosen and fasten bolts and screws with a hexagonal socket in the head. Hex keys offer several advantages over conventional spanners and screwdrivers. The tool makes it very easy to loosen and fasten small and difficult to reach bolts, and can be used with headless screws as well. The six contact surfaces between the bolt and driver offer good grip and enable faster operation. The tool is extremely small, light, portable and affordable. Torx keys are similar to hex keys, but instead of a hexagonal cross-section, they have a star or asterisk-shaped cross-section. These keys are used to fix and remove the highly popular and tamper-proof Torx screws. Torx screws find varied application on automobiles, disc brakes, consumer electronics, hard disk drives and even construction sites. Hex keys with T-handles offer a cushioned feel to the tool, increasing comfort. T-handles are welded directly to the hex key and match the torque capacity of the key. These handles have a slight downward angle to improve functionality and reduce fatigue. Hex keys and Torx keys come in various sizes, blade lengths and grip sizes. The torque capacity depends on the length and thickness of the key.
