Chicago screws, also known as binding posts, are essential for joining multiple layers of BioThane® or other materials in DIY projects such as collars or dog leashes.
Choosing the right size and installing it correctly
The thickness of the material you are using determines the correct Chicago screw size. Choose a Chicago screw whose screw nut is approximately 2 mm shorter than the total thickness of the material that is being connected. These screws offer a strong, reusable hold and are easy to install. For best results, apply a drop of Loctite before tightening. Available in various sizes and finishes, Chicago screws are a practical choice for both hobbyists and professionals in leathercraft and strapwork.
