What are the requirements for the surface treatment process of the wrench

The flywheel wrench tubular spark plug wrench is a commonly used installation and removal tool. It uses the principle of leverage to turn bolts, screws, nuts, and other threads to hold the openings or sockets of bolts or nuts. Bright chrome: bright like a mirror. Chromite: dull. Electrophoresis: black, bright, under the action of external direct current, the charged particles move towards the cathode or anode in the dispersed medium force to promote the separation of substances. Phosphating: black, but with a dark gloss. When the substance is immersed in the phosphating solution, a layer of water-insoluble crystalline phosphorus is deposited on the surface of the toilet, which is the process of hydrochloric acid conversion. Gray nickel: It is a brand-new surface treatment method with strong anti-rust ability and will increase the service life of the product. Other treatments include blackening, nickel-iron alloy, pearl nickel, black nickel and titanium plating.

We don’t use wrenches frequently in our daily lives, but for some machinery manufacturers or large machinery, their necessary tools are wrenches. The following wrench manufacturers will introduce how it works. Wrench is a common installation With disassembly tools. Use the principle of leverage to turn bolts, screws, nuts, and other threaded hand tools that hold the openings of bolts or nuts or sleeve fasteners. Wrenches are usually made with clamps on one or both ends of the handle to apply external force to the handle to apply external force to turn the bolt or nut to hold the opening or sleeve of the bolt or nut. When in use, an external force is applied to the shank along the thread rotation direction, and the bolt or nut can be turned. There are basically two types of cross wrenches, dead wrenches and adjustable wrenches. The former refers to the wrench that has a fixed number written on it, and the latter is the adjustable wrench.

One or both ends are made with a fixed size opening for screwing nuts or bolts of a certain size. Torx wrench: Both ends have working ends with hexagonal holes or twelve-angle holes, suitable for occasions where the working space is narrow and ordinary wrenches cannot be used. Dual-purpose wrench: one end is the same as the single-head wrench, the other end is the same as the torx wrench, both ends are screwed with bolts or nuts of the same specification. Adjustable wrench: The width of the opening can be adjusted within a certain size range, and it can turn bolts or nuts of different specifications. The structural feature of the wrench is that the fixed jaws are made into flat jaws with fine teeth; one end of the movable jaws is made of flat jaws; the other end is made of concave jaws with fine teeth; push the worm down to move The jaws can be quickly removed and the position of the jaws can be changed.

Hook wrench: also known as crescent wrench, used to turn flat nuts with restricted thickness. Socket wrench: It is composed of multiple sockets with hexagonal holes or twelve-angle holes and equipped with handles, posts and other accessories. It is especially suitable for screwing bolts or nuts with very narrow positions or deep recesses. . Allen wrench: L-shaped hexagonal rod-shaped wrench, specially used to turn hexagon socket screws. The model of the hexagonal wrench is based on the size of the opposite side of the hexagon, and the size of the bolt has national standards. Purpose: It is specially used for fastening or dismantling round nuts on machine tools, vehicles, and mechanical equipment. Torque wrench: It can display the applied torque when turning a bolt or nut; or when the applied torque reaches a specified value, it will emit a light or sound signal. Torque wrenches are suitable for installations with clearly defined torque.
