Box End Wrenches (Explosion-Proof)

A box wrench (explosion-proof) is a work tool with a ring-shaped tip that does not generate sparks even when shocked by hitting or frictional resistance is applied. It can be used safely even at the site where there is a risk of explosion. Box wrenches (explosion-proof) include double-ended box wrench, single-ended box wrench, and box wrench with bolt-hole aligner. Copper is the main raw material, but a box wrench (explosion-proof) containing a small amount of beryllium has strength comparable to that of general work tool steel. Especially when using an explosion-proof single-ended striking wrench, a beryllium copper alloy is suitable. In addition to the standard offset 45° and 12-point box wrench, there are various types such as offset 60° and S-shape, so choose it according to your work application.
