Clear polycarbonate fastener sets, also known as binding posts or Chicago screws, are durable, transparent fasteners perfect for securely joining materials while maintaining a clean, professional look. Commonly used in applications such as binding documents, assembling signs, or securing panels and displays, these fasteners are ideal for projects that require both strength and a polished appearance. Typical uses also include binding rigid or flexible plastic, leather, swatch book fabric & paper, key cases, etc. The clear polycarbonate material blends seamlessly with different surfaces, making them versatile for a range of uses, including retail displays, crafts, and other DIY projects.
Clear polycarbonate fastener sets consist of a female-threaded post and a slotted-head 8/32 thread cap screw. Typical uses include binding rigid or flexible plastic, leather, swatch book fabric & paper, key cases, etc.
When installing binding posts, we recommend drilling a ¼” diameter hole, then installing the post and screw, using gentle pressure to avoid stripping thread.
