Chicago screws are essential for joining multiple layers of BioThane® in DIY projects such as collars or dog leashes. BioThane® is typically 2.5mm thick, making a 5mm book screw ideal for securing two layers. 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.
