Hex Keys Non -Sparking

Secure Tool's Non-Sparking hex key is an L Shaped tool that is designed to tighten or loosen a screw, or bolt with a hexagonal socket. The hex key comes in a variety of sizes, and it is usually sold as a set. Hex keys can have measurements in inches or millimeters. It’s a type of Allen wrench. 

The Non-Sparking tool is usually held and twisted by its long arm, creating a relatively large torque at the tip of the short arm; it can also be held by its short arm to access screws in difficult-to-reach locations and to turn screws faster at the expense of torque
