Explosion proof bent handle wrenches are mostly suitable for fastening or disassembling one or two specifications of hexagonal or square head bolts and nuts in flammable and explosive places.

The materials are beryllium bronze and aluminum bronze alloy, with beryllium bronze having a working face hardness of HRC35 ° or higher and a tensile strength of δ b>105-120kgf/mm2; The working surface hardness of aluminum bronze material is HRC25 ° or above, and the tensile strength is δ b>75-85kgf/mm2; The beryllium copper alloy explosion-proof tool also has anti magnetic function, and can be used normally in working environments with magnetic fields.

Explosion proof bent handle wrench is a common wrench style, with a striking end at the tail of the product and a fixed size opening at one end for turning nuts or bolts.

Specifications: 17mm, 19mm, 22mm, 24mm, 27mm, 30mm, 32mm, 36mm, 41mm, 46mm, 50mm, 55mm, 60mm, 65mm, 70mm, 75mm, 80mm, 85mm

After the product is formed, it undergoes high-temperature bluing treatment. In a high content solution of sodium hydroxide and sodium nitrite at a temperature above 140 degrees Celsius, a dense oxide film (Fe2O3 and Fe3O4) is formed on the surface of the steel parts. Different steels will have different color differences, which are independent of roughness; The bluing film is not effective, so it needs to be treated with rust proof oil after bluing. Other surface treatments can also be carried out according to customer requirements.
