About this Calculator

What is it for?

This calculator can be used as an aid to help estimate the weight of bolts, nuts, and washers. We provide it as a resource for our customers, because the weight of a bolt or assembly is often needed when calculating shipping costs, or jobsite delivery requirements.

How does it work?

The calculator uses super-secret combinations of theoretical and sampled dimensions and weights to provide the results. For sizes that don't actually exist in the marketplace, such as a 1-63/64" diameter square nut, we make a guess based on what we know about the relationship between diameter and other dimensions.

What's with the results?

Sometimes, the "Weight per each" that you see times the "Quantity" doesn't equal the "Total weight". Since this calculation is intended for estimation purposes and is not intended to be precise, we round the values for output to the screen. As such, the displayed weight per each piece is a rounded version of the value that the calculator uses to determine the total weight.
