## Description and construction

Use these metal 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 (100 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.

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

* Tolerates occasional contact with rain, wet grass or damp hands. Regular soaking accelerates visible wear, so dry the surface after it becomes wet.
* 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 appears first where a 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.
