Weights Of Mild Steel Bolts And Nuts
Description
This section is from the book "Notes On Construction In Mild Steel", by Henry Fidler. Also available from Amazon: Notes On Construction In Mild Steel.
Weights Of Mild Steel Bolts And Nuts
The following table of the weights of mild-steel bolts and nuts may be found useful in the process of estimating weights of steel-work and fastenings.
The heads and nuts are hexagonal, of the usual Whitworth standard size; that is, the depth of the head is seven-eighths of the diameter of the bolt, and the depth of the nut is equal to the diameter. The dimensions of the head and nut across the flats or over the angles of the hexagon are those usually given in the published tables of sizes of Whitworth standard.
Any departure from the above proportions of head and nut will of course modify to some extent the weights given in the tables.
The table may also be used for the calculation of weights of similar bolts in other materials than mild steel by proportioning in the ratio of the specific gravities of the material used.
The length of the bolt is in all cases measured from under head to point, and the lengths have been extended to 30 inches in the table to meet the ordinary cases of long bolts used in the connection of heavy timber framing. For longer bolts, such as foundation bolts and the like, special calculations must be made, using the values of the weight of heads and nuts given at the head of the table.
The weight of washers is not included, and must be allowed for separately.
