Flat washer standard, know this knowledge to choose more standard [hardware]
Flat washer standard. Because of the complexity of fasteners, many friends often have doubts about how to choose when choosing. Xiaoshuo uses 15 years of work experience to sort out a few points and share with you: 1. Selection Attention should be paid to the problem of electrochemical corrosion when different metals are in contact with the gasket material. The material of the flat washer is generally the same as that of the connected parts, usually steel, alloy steel, stainless steel, aluminum alloy, etc. When electrical conductivity is required, copper and copper alloys can be used. 2. The inner diameter of the flat washer should be selected according to the larger value of the thread or screw diameter. The outer diameter of the connected material is soft (such as composite material) or matched with the spring washer. The larger value should be selected. 3. When choosing to place the W washer under the bolt or screw head, in order to avoid interference between the fillet under the head and the washer, a flat washer with an inner hole chamfer can be used. 4. Steel washers should be used for important bolts with larger diameters or in order to increase the anti-extrusion ability. Steel washers shall be used for the connection of tension bolts or tension-shear composite bolts. 5. Special gaskets are used in locations with special requirements. Copper gaskets can be used if electrical conductivity is required; sealing gaskets with air tightness requirements can be used.
