A hand tool used to turn bolts, screws, nuts, and other threaded fasteners to hold openings or sockets of bolts or nuts.Material:1. Chrome vanadium steel: chemical symbol CR-V, which is of good quality in steel;2. Carbon steel: average quality.Design:1. Solid wrench: one or both ends are provided with fixed size openings for turning nuts or bolts of certain size.2. Ring spanner: both ends of the spanner have working ends with hexagonal holes or twelve holes, which is suitable for the occasions where the working space is narrow and the ordinary spanner cannot be used.3. Dual purpose wrench: one end is the same as the single end solid wrench, the other end is the same as the ring wrench, and both ends turn the bolts or nuts of the same specification.4. Adjustable spanner: the opening width can be adjusted within a certain size range, and the bolts or nuts of different specifications can be screwed. The structure of the wrench is characterized in that the fixed jaw is made into a flat jaw with fine teeth; one end of the movable jaw is made into a flat jaw; the other end is made into a concave jaw with fine teeth; pressing the worm downward, the movable jaw can be quickly removed and the jaw position can be changed.5. Hook spanner: also known as crescent spanner, it is used to turn flat nuts with limited thickness.6. Socket wrench: generally known as socket: it is composed of multiple sockets with hexagon or twelve hole and equipped with handle, extension bar and other accessories, especially suitable for bolts or nuts with very narrow or deep depression. There are metric system and British system for the sleeve. Although the concave shape of the sleeve is the same, the outer diameter and length are designed for the shape and size of the corresponding equipment. There is no unified national regulation, so the design of the sleeve is relatively flexible and meets the needs of the public. The socket wrench is generally provided with a set of socket heads of various specifications, swing handle, extension bar, universal joint, screwdriver joint, elbow handle, etc. for inserting hexagon nuts. The socket head of the socket wrench is a concave hexagon cylinder; the wrench is usually made of carbon structural steel or alloy structural steel, the wrench head has the specified hardness, and the middle and handle parts are elastic.7. Allen wrench: a L-shaped hexagonal bar wrench, which is specially used to turn the Allen screw. The model of Allen wrench is according to the size of opposite side of hexagon, and the size of bolt has national standard.Purpose: it is specially used to fasten or dismantle round nuts on machine tools, vehicles and mechanical equipment.8. Torque wrench: it can display the applied torque when turning the bolt or nut; or when the applied torque reaches the specified value, it will send out light or sound signal. The torque wrench is suitable for the assembly with the specified torque. Manual spanner is also called ordinary spanner. It is mainly used in ordinary life and work. It is relatively simple to use. It is mainly divided into single head solid spanner, double head solid spanner, adjustable spanner, ring spanner, multi-purpose spanner, knock spanner, socket spanner, torque spanner, torque spanner, cross spanner, ratchet spanner, hook spanner, hexagon wrench, square wrench and hand Dynamic clutch type torque wrench, pipe wrench, T-wrench, l-wrench, Trident wrench, crescent wrench, oil barrel wrench, tire wrench, spark plug wrench, filter wrench, combination wrench, other wrenches, etc. Torque spanner is divided into sound spanner, pointer spanner and digital spanner.Use of hand spanner:1. Select the corresponding spanner according to the characteristics of the fastener to be fastened.2. Tighten, hold the end of the handle with hand, and tighten it in clockwise direction; loosen it, and rotate it in anticlockwise direction.Features of hand wrench:Simple operation, low price and high labor intensity.Application and technical characteristics of open spanner:Screw is the main fastener in mechanical equipment. The open spanner is an important tool for machining, production and maintenance in mechanical industry. This project is a revolution of traditional spanner tools, which has the following advantages.1. It can work fast. Its working speed is three to four times faster than that of traditional board hand, and faster than that of fast board hand.2. An open-ended wrench can be used for 2-6 kinds of screws, while a double headed wrench can only be used for 2 kinds of screws.An open board hand is equivalent to 2-3 mechanical hands, which is equivalent to a movable board hand, but it can work quickly without adjusting the opening.3. It has a long service life and can't be broken, and the front quick plate hand is easy to be broken.4. The manufacturing process is simple, and the cost is even lower than that of the stiff hand.5. Light weight, easy to carry and labor-saving.Product Information:Item NO.KNFY-66MaterialCarbon SteelSize6MM 31x74MM,6MM 35x125MMProduct Weight0.022KGMOQ10000PCSSurface TreatmentGalvanizedProduct Pictures:
