## Description and construction

Use these stainless steel Chicago screws for belts and collars or to join two materials. Each screw has two parts: a hollow post with an internal thread and a solid head, which works as a closed nut, and a matching screw that tightens the joint. A screwed joint comes apart quickly, for example when you change a belt buckle. The price is for the whole pack (10 pcs).

How to choose the right screw length?

The total thickness of the joined material decides, whether it is leather, webbing or anything else. The length of the screw post (value B in the table) should be 2 mm less than that thickness.

The Chicago screws SS SPH-6-H differ from the standard version in head thickness: the head is approximately 1 mm thicker.

Tip: To keep the joint from working loose over time, put a drop of thread-locking adhesive #1918997 on the thread before you screw it together.


## Limits and maintenance

* The finish does not increase corrosion resistance. Either the underlying material does not need it, or the finish is purely aesthetic.
* Designed for daily use with frequent contact against straps, snaps or other hard surfaces. Visible wear develops more slowly than in the lower resistance classes.
* Gradually loses some of its original gloss and may change tone slightly. This is a visual change and does not by itself affect the function of the part.
