Standard Washer Size & Weight Guide by Rebolt Alloys

Knowledge of dimensions and weight of washers is used to achieve accuracy in the planning, buying and loading calculations in construction, engineering and industrial work. Rebolt Alloys developed this Washers Weight Chart in Kg to provide contractors, architects and project engineers with a clear reference in terms of choosing the appropriate size of the washer and keeping track of the overall assembly weight without any doubts. You need to estimate the bulk order requirements, or need to make sure that it will be compatible with bolts and structural components; this chart will be a resilient and simple-to-use guide to any project.
