Square flat washers

The manufacturer hardware responsible for the manufacture of square flat washers said that although every assembly and fastening process requires various components to run successfully, the washers are an important part. Washers can be used under the heads of fasteners, bolts, screws or under nuts or combinations. Gaskets are designed to perform functions in specific applications; these can be locking, load spreading, protection, decoration, tension indication, sealing or a combination of these roles. Washers are also important to prevent galvanic corrosion, especially by insulating steel screws from aluminum surfaces. The following Xiaoshuo takes you to look at the several classifications of flat washers: 　　1, flat washers 　　The main function of flat washers is to distribute the bearing surface pressure, clamping load, bolts or nuts on a larger surface area to prevent damage.　　 Washers are mainly manufactured in accordance with standard specifications of various sizes, materials and shapes. Flat washers are thin and flat round general purpose washers with a hole in the middle. The inner and outer shapes are usually circular. Depending on the function of the gasket, the hole or outer diameter can be asymmetrical. The flat washer size is represented by the shank diameter of the fastener, where they form part of the assembly.　　2, square washers 　　 construction square washers should be used instead of round washers for timber construction and concrete floor applications; they are used with all fasteners for greater load distribution and bolts passing through walls or wood.　　3. Square hole washer 　　 is used in woodworking and fence industries to combine wheel bolts and body screws with a square section below the bolt head; the washer is located on the square below the bolt head.　　4, conical washer 　　 conical washer is designed to be used in the channel part, under the nut with a conical flange, so that the bolt assembly can fit into a square shape when tightening. 5. Spring washers Split Lock washers Spiral spring washers provide anti-vibration function, they are separated by a ring on the ring and bent into a spiral shape, which makes the washer apply elastic force between the head of the fastener and the supporting surface to keep the washer Tighten the nut or threaded hole against the face and the bolt hard, resulting in greater friction and rotation resistance. The spring washer is a left-handed screw, allowing the thread to be tightened clockwise in the right hand. When a left rotation movement is applied, the raised edge bites into the underside of the bolt or nut and the part fixed to the bolt to resist rotation. The spring washer is not effective for left-handed threads and hardened surfaces, and should not be used in conjunction with the flat washer under the spring washer, because this prevents the spring washer from biting into parts that resist rotation. Spring washers are produced in accordance with various standards, indicating thickness and cross-sectional dimensions, usually square or rectangular cross-sections. The popular spring washers are single coils, but they can also be provided as double coil washers.　　6. u200bu200bRibbed contact lock washers 　　 Washers with surface ribs and serrations on one or two flat surfaces are designed to engage connecting materials or bolts or nuts to change electrical contact or locking action.　　Any type of material that can be punched, pressed or cut can be made into flat washers. Washers are made of various metal and non-metal materials, including low carbon steel and high carbon steel, stainless steel and steel alloys, copper-based materials, beryllium copper, phosphor bronze, titanium, aluminum, fiber, mica, polyester film, rubber, Nylon, PTFE and phenolic resin.　　 The gasket material is important because certain applications require specific materials to ensure that the gasket can withstand environmental conditions. For example, if the washer undergoes cyclic loading, strength is an important design criterion, and high-alloy steel or spring steel is required in the case of springs and disc washers. When the gasket bears a light load or a soft surface that may be damaged by a metal gasket, use non-metallic materials, etc. Hardware, 15 years of focus on square flat washers, 5,000 square meters production workshop, hundreds of precision processing and production equipment, more than 20 Ru0026D and design engineers, metal flat washers with an accuracy of 0.01mm, 3 million punching next-day production capacity, 16 quality inspections Starting from raw materials, we strictly control each level. Can quickly solve the problems of time, accuracy and quality for you!
