Hex Wrenches (Explosion-Proof)
Hex keys (explosion-proof) are an explosion-proof tool made of a material that does not generate sparks due to friction or impact when tightening hex socket head bolts. In an environment where flammable gases or flammable liquids are used, such as in explosives manufacturing plants and medical equipment maintenance sites, those molecules are suspended in the air, and sparks during work may cause ignition or explosion. There are L-shaped and T-shaped types, but the L-shaped type is often used because the short part and the long part can be used according to the application. Regarding materials, it is safer to use those that are specialized in explosion-proof certified by the US accreditation body FM Approvals or UKAS, the United Kingdom Accreditation Service. Hex keys have not only explosion-proof type, but also non-magnetic and corrosion-resistant types. Some are sold in single units, and the set type is placed in order of size, making it easy to use and organize.
