How to calculate the weight of the national standard hexagon fastener

It's a bit cumbersome to calculate, and standard parts like this have weight charts.

How to calculate the weight of the hexagon nut, fastener consultant Yu Wenlong believes that the total weight volume of the hexagon nut minus the volume of the internal threaded hole, and then multiply by the nut density. Generally, the weight of the nut is divided into theoretical weight and actual weight, and the theoretical weight can be checked in the table. Yu Wenlong, a fastener consultant, believes that it is best to check the relevant information by yourself, and it is always fake on the Internet.

How to calculate the weight of the bolt, the fastener consultant believes that the calculation of the weight of the bolt is very simple, if it is a hexagonal bolt, it is the weight of the hexagonal head plus the weight of the screw, if it is a screw, it is the weight of the screw. It's just that you don't need to calculate it, and you can check the table directly. It's best to check the relevant information yourself, it's always fake on the Internet, and if you encounter someone who doesn't know how to pretend to understand, you can answer casually, and if it's fake or deceitful, it will directly mislead you, and even mislead you.

The most standard algorithm is to multiply the volume by the specific gravity, if you really don't know how to calculate, you can take 100 and weigh it on the electronic scale, divide by 100, it is a single weight.

The best way is to look up the table, basically the fasteners can be obtained by looking up the table. The calculation is troublesome and difficult to get right.

The national standard has fastener quality, the American standard has the seventh edition of the IFI, and the eighth edition of the latest American fastener standard FII can only find various data, but not the weight.

To make American screws, you must have American screw standards. You should buy a set of the latest American fastener standards encyclopedia "IFI British Fastener Standards Manual" eighth edition (English edition) (published in 2011), experts are the winners, and having standards will have related business.

Volume * density, the general density is calculated according to it. And it's best to weigh it up and down.

Nut volume multiplied by nut density The standard weight is the total weight calculated as 1000 pieces.

What is the weight of 1,000 8*20 screws? Yu Wenlong, a fastener consultant, believes that there are many standards for screws, many materials, different screw standards, different materials, and different weights, so it is impossible to determine the weight of 1,000 8*20 screws based on the current information.

Yu Wenlong, a fastener consultant, believes that it is best to check the relevant information by yourself, and it is always fake on the Internet. The light ones are unqualified in terms of product quality, and the heavy ones will be fined. Of course, fastener consultant Yu Wenlong believes that if you have the strength, ask a fastener consultant to refer to your technology, grasp the direction of enterprise development, positioning products, positioning customers is also a good choice.
