Products Description
The Chicago Bolt is a detachable fastener consisting of a male and female component. Its core feature is the interlocking of a hollow female screw and a matching threaded rod, achieving reliable fastening of multi-layered materials through axial clamping force. Unlike traditional rivets, which are formed in one piece, this bolt allows for repeated assembly and disassembly, balancing structural strength with ease of maintenance. This type of fastener is widely used in industrial structural component connections, equipment panel mounting, insulation laminate assembly clamping, and modular systems requiring periodic disassembly and maintenance.
Design Advantages
Weight Reduction
Compared to traditional bolts, the Brass Chicago Screw effectively reduces overall weight through optimized material distribution.
Easy Installation
Electrical Panel Chicago Bolt's unique structural design allows for locking without the need for additional fasteners during assembly.
Loosening Prevention
Traditional bolts are prone to loosening under repeated vibration or temperature changes, while the Chicago Screw Rivet maintains a long-term tight fit.
Frequently Asked Questions
What is the difference between Ledger Screw and ordinary bolts + nuts?
+
-
Electrical Panel Chicago Bolt has a "two-piece" structure, resulting in a flat finish on both sides after installation, taking up less space and having a neat appearance. They are suitable for scenarios requiring frequent disassembly and assembly or where aesthetics are important. Ordinary bolts + nuts have a bolt head on one side and a nut on the other, with a protruding structure that takes up more space.
What does a material utilization rate >85% mean?
+
-
Cold heading is formed directly from wire, resulting in less waste and a material utilization rate exceeding 85%, higher than machining (approximately 40-60%). Advantages include: lower raw material costs, higher production efficiency, continuous metal flow lines, and superior strength, making it suitable for mass production.
How is a dimensional tolerance of ±0.05mm achieved?
+
-
Through multi-station cold heading die control, combined with precision die processing and process parameter control; full inspection of the first piece; and SPC monitoring during mass production. If necessary, additional forming stations are added to ensure dimensional stability within ±0.05mm.
Can the Chicago Screw Rivet be used in vibrating environments?
+
-
It is recommended to use anti-loosening designs, such as nylon anti-loosening structures, thread anaerobic adhesive, spring washers, or fine threads, and to verify the anti-loosening performance under high vibration conditions.
Application Areas
Electronics and Electrical Engineering
Brass Chicago Screw is used for the assembly of precision electronics, instruments, and communication equipment, such as fixing circuit boards, housings, and junction boxes. The non-protruding design avoids interference with electronic components, ensuring stable and secure equipment operation.
Medical Devices
Chicago Screw Rivet is adapted for medical device assembly. Materials meet medical-grade standards, are free of harmful substances, and have a smooth, burr-free surface. The detachable and reassembleable design facilitates equipment maintenance and sterilization.
High-End Furniture and Decoration
Electrical Panel Chicago Bolt is used for fixing high-end furniture and decorative panels. The aesthetically pleasing, flush installation enhances the overall look. The detachable and reassembleable design facilitates disassembly and transportation.
