Fastener Dimensions

Fastener dimensions are very important for fastening projects. If the actual size of fasteners is less than standard size requirements or client’s requirements. It is difficult for the end-user to install due to the size deviation.

The most important thing is that due to the size problems, such as the thickness is too thin, the opposite side is too narrow, the tooth spacing, or the diameter of the screw and so on, when using substandard fasteners, especially in the construction industry, machinery industry, agricultural machinery and so on, it will lead to major accidents.

So it is very important to test the size and mechanical properties of fasteners before production and delivery.

Here we show you the size test results of our nuts, bolts, and screws. All fasteners are randomly selected to show the correctness of the results.
