Laser Cutting Tip: When cutting mounting holes in acrylic, always test your hardware fit before cutting an entire production batch. An approximately 4.5 mm clearance hole is a useful starting point for an M4 threaded shaft, but the receiving post may require a larger opening.
What are Chicago screws? Chicago screws are two-piece fasteners consisting of a threaded screw and a receiving post. They are commonly used to connect layered materials without permanent adhesives.
Can Chicago screws be used with acrylic? Yes! Chicago screws are a convenient option for connecting laser-cut acrylic pieces, especially dimensional signs, layered accessories, and projects that may need to be disassembled.
Do Chicago screws work with leatherette? Yes. Chicago screws can fasten multiple layers of leatherette or combine leatherette with acrylic for custom accessories, tags, and decorative projects.
What does M4 mean on Chicago screws? M4 refers to the nominal 4 mm diameter of the threaded screw shaft. It does not indicate the diameter of the screw head or receiving post.
What length Chicago screw do I need? Measure the combined thickness of the materials you're connecting. Our Chicago screws are available in 6 mm, 8 mm, 10 mm, and 12 mm lengths to accommodate different projects.
Are Chicago screws permanent? No. Unlike rivets or adhesive, Chicago screws can generally be unscrewed and reused, making them ideal for adjustable or interchangeable layered designs.
Pair our Chicago screws with CMB Acrylic sheets, laser-cut blanks, and leatherette materials to create layered designs with a professional finish. From dimensional signs to custom accessories, these versatile fasteners make assembly simple while adding a decorative touch.
