## Description and construction

Metal Chicago screws are used for making belts, collars, or for joining materials. They consist of two parts – a hollow screw with an internal thread and a solid head that acts as a closed nut, and a matching screw for tightening the connection. The advantage of a screw connection is quick and easy handling, for example when replacing a belt buckle or joining two materials. The listed price is for the entire pack (100 pcs)!

How to choose the correct screw length?

Whether you are joining leather, webbing, or another material, the key factor is the material thickness. The correct size of a Chicago screw is when the length of the screw post (value B in the table) is 2 mm shorter than the total thickness of the joined materials.

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

* Tolerates contact with water — rain, wet grass, damp hands. With regular soaking the finish ages faster and loses appearance. Better to dry after wetting.
* Provides a temporary barrier against moisture. Works well in dry environments, but protection weakens over time with regular contact with water or sweat.
* Thin decorative coating that gradually wears through with regular wear and friction. Wear shows fairly quickly at points where buckle or snap contacts the strap, ring or fur.
* At points of regular friction — typically the buckle edge, snap contact point or strap — the finish gradually wears through and the base material shows beneath.
