Beveled Flat washer is a assemblage of accouterments acclimated with a array of bolts and band devices. While a accepted washer is Flat on both abandon with alongside surfaces, a askew Flat washer has one angled ancillary and one flat. This angled face can be acclimated to acclimatize the bend of a bolt to actual for imperfections aural the anatomy or architecture of the object.
The primary action of a askew Flat Washer is shimming or leveling an account that's out of alignment. This ensures that the ballast or bolt will fit deeply to the surrounding anatomy to actualize a defended connection. In animate construction, askew Flat washers are generally acclimated to accommodated bounded architecture codes apropos the fit and alignment of fasteners. A accepted animate axle includes flanges, which about accept a slight slope. When a askew Flat washer is amid amid the border and a bolt, the washer allows the arch of the bolt to sit alongside to the border as appropriate by code.
Beveled washers are intended for American Standard beams and channels in structural applications, to compensate for lack of parallelism. For beveled washers to be used with A325 and A490 structural bolts.

To assure proper bolt performance, it is required in the 2004 RCSC Specification Section 6.1.1 that the surfaces against which the head and nut bear have a slope not greater than 1:20 with respect to the plane normal to the bolt axis.
American standard beams (S-shapes) and channels are rolled with beveled flanges that exceed this limit. Because bolt holes are made perpendicular to the outside face of these flanges, a beveled washer must be used at the inside face to provide the required parallelism. Beveled washers are made square or rectangular so that they can more easily be prevented from turning to assure that the bevel is oriented in the proper direction.
