Products Description

Chicago Binding Screws are threaded fasteners consisting of male and female parts, widely used in electrical connections, mechanical assembly, and industrial control equipment. Since 1990, we have focused on providing high-precision, high-reliability metal fastener solutions for electrical components such as relays, switches, contactors, and circuit breakers. These products are particularly suitable for electrical panels and control systems requiring frequent disassembly and stringent requirements for conductivity and mechanical strength.
Whether used as Chicago Screw Rivets for riveting and fixing or as Post and Screw Fasteners for modular assembly, our products maintain stable performance in harsh electrical environments, meeting diverse needs from low-voltage control to high-voltage power distribution.
Product Features and Functions
Quick Installation and Removal
Brass Chicago Screws can be manually locked without tools, suitable for on-site commissioning.
Excellent Conductivity
Chicago Screw Rivets are suitable for internal terminals in relays and contactors.
Vibration-Resistant and Loose-Proof Design
Precision threaded fit, suitable for high-frequency vibration environments in circuit breakers and switches.
Aesthetically Pleasing and Flat
Electrical Panel Chicago Bolts meet the requirements of panel aesthetics and space constraints.

Manufacturing Process
Precision Stamping: High-precision stamping equipment ensures the coaxiality and flatness of the Ledger Screw head and column.
CNC Machining: Key dimensions are machined using CNC lathes to ensure the thread accuracy and fit tolerances of the Post and Screw Fastener.
Heat Treatment: The Chicago Screw undergoes heat treatment to improve material toughness and fatigue resistance.
Surface Treatment: Electroplating, passivation, and other processes enhance the corrosion resistance and wear resistance of the Chicago Bolt.
Assembly and Inspection: Every Stainless Steel Chicago Bolt undergoes dimensional inspection, torque testing, and visual inspection before leaving the factory to ensure 100% compliance.

Industry Application Cases
