Explosion proof single head 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; Beryllium copper alloy explosion-proof tools also have anti magnetic function and can be used normally in working environments with magnetic fields.

Explosion proof single end wrenches are divided into two types: metric and imperial. It is a tool used in equipment installation, installation, and maintenance work.

The manufacturing standard for explosion-proof single headed wrench: GB/T4392-1995 (tapping wrench and single headed wrench).

The material of the explosion-proof single head wrench: The single head wrench is made of forged 45 # medium carbon steel or 40Cr alloy steel as a whole.

The use of explosion-proof single head wrench: Large industrial single head wrench is suitable for industries such as petroleum, chemical, metallurgy, power generation, refining, shipbuilding, petrochemicals, and machinery.

The characteristics of explosion-proof single head wrench: The single head wrench is forged from medium carbon steel or alloy steel as a whole, with stable structure, high material density, reasonable design, strong impact resistance, no bending, no bending, high dimensional accuracy, and durability.
