Chamfer washers have one sloped and one flat side, used to adjust the angle of a bolt to correct for imperfections. They are used to shim or level a misaligned feature in steel construction and must be installed carefully to meet the needs of the application. Users need to match the material to the application and choose square or rectangular units to improve installation accuracy. The washer should also be carefully sized to fit the fastener.
A chamfer washer is a unit of hardware used with a variety of bolts and fasteners. While a standard washer is flat on both sides with parallel surfaces, a chamfered washer has one sloped and one flat side. This angled face can be used to adjust the angle of a bolt to correct for imperfections within the structure or design of the object.
The primary function of a bevel washer is to shim or level a misaligned feature. This ensures that the fastener or bolt fits snugly into the surrounding structure to create a secure connection. In steel construction, chamfer washers are often used to meet local building codes regarding fit and alignment of fasteners. A standard steel beam includes flanges, which typically have a slight slope. When a chamfered washer is inserted between the flange and a bolt, the washer allows the head of the bolt to sit parallel to the flange as required by the code.
The chamfered face of these washers must be installed carefully to meet the needs of the application. When the chamfered face is installed opposite the bolt head, it can help minimize force or stress on a specific part of the fastener. When reversed so the blunt side faces away from the bolt, the washer can distribute the weight of the force more evenly across the entire structure.
When choosing a bevel washer, users need to match the material to the application. Iron washers are the most malleable and can provide some flex for expansion and contraction. Steel units are the hardest and provide the greatest strength for structural applications. If the washing machine will be exposed to moisture or chemicals, stainless steel should be chosen to minimize the effects or rust and corrosion.
While chamfer washers can be round or square, most users choose square or rectangular units to improve installation accuracy. Square or rectangular washers help align the chamfer properly with the surrounding fastener or object. This type of design is also less likely to rotate around the bolt, which is a common occurrence with round washers.
A chamfered washer should also be carefully sized to fit the fastener. The hole in the washer should be small enough to prevent the fastener head from going through, but large enough for the bolt rod to pass through easily enough. Users also need to consider washer thickness and bevel slope.
