Compared to wrench wrench with a wrench and generally speaking, explosion-proof wrench is that people often use to a hardware tool, it is made of high quality carbon steel or diamond overall forging, such as single / double headed wrench, sleeve wrench, a bucket, the valve wrench, etc. are explosion-proof wrench. It common rivals, the design structure to complex much, material density is high, the fight against ability is stronger, the product size precision is high, at the same time, it is not easy to be broken and bending, and the service life is much longer. And an ordinary wrench, explosion-proof wrench in bit selection requirements more stringent, so can improve the daily work efficiency.
People love to use explosion-proof wrench on the one hand because of its bright, clean and tidy appearance. Its surface treatment is after grinding, unusually bright. Sometimes people find occurred on the surface of the rust, black, the reason is because in the process of surface treatment and the surface in the air, no after treatment process, oxidation resistance, the result is oxidation reaction occurred in the water molecules and the metal air, resulting in the phenomenon of rust, in order to avoid the occurrence of such things, hardware tools manufacturers in the wrench handle must be in the process of high resistance to corrosion and oxidation process of the necessary processing.
Another is its high standards of internal quality. Compared with the traditional wrench has the advantages of simple production, low national standard requirements, explosion-proof tool types of products in the domestic quality requirements are more stringent, such as its ability to work under pressure, the size of the torque, mechanical strength, and much in the appearance of trachoma, bending, etc. must after party validation of national standards can be manufactured for sale.
