## Description and construction

Brass Chicago screw is used for making belts, dog collars, and to join various materials. It consists of two parts, a hollow screw with solid head and internal thread, which serves as a closed nut, and the opposite screw part to tighten up the join. The advantage of the screw connection is the ease of handling, for example, when changing belt buckles or joining two materials. The price listed is for the entire package (10 pcs)!

How to chose the correct screw length?

Whether we work with leather, webbing, or any other material, its thickness is always the deciding factor. The proper size of a Chicago screw is when the length of a screw nut (value B in the table) is 2 mm less the total thickness of a material that's being connected.

TIP: To ensure a 100% solid connection it will suffice to apply a drop of thread locking adhesive to the screw #1918997.


## Limits and maintenance

* The finish does not increase corrosion resistance. Either the underlying material does not need it, or the finish is purely aesthetic.
* Resists daily use even with active dogs. The surface holds its original appearance for a long time, even when in contact with straps, snaps or other hard surfaces.
* Over time loses its original gloss and the tone changes slightly. This does not affect function, but the surface eventually does not look as fresh as at the start.
