Chicago screws are essential for joining multiple layers of BioThane® or other materials in DIY projects such as collars or dog leashes. 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.
