## 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.

Screws in sizes 15 and 20 mm (#SPH-15, #SPH-20) are mainly used for making leather key fobs.


## Limits and maintenance

* Handles typical outdoor conditions without issue — rain, mud, moisture, sweat. No need to dry or treat specially after every water contact.
* Reliably protects the underlying material during typical outdoor use — rain, dew, occasional wetting. May not be sufficient for permanently wet environments.
* Handles normal everyday wear. At exposed points — where regular friction or contact with other metals occurs — traces of wear may appear over time.
* 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.
