Frequently Asked Questions (FAQ)

Q1: What are the main advantages of brass binding screws over steel?
Brass binding screws offer superior electrical conductivity, natural corrosion resistance, and non-magnetic properties compared to steel fasteners. While steel provides higher tensile strength, brass delivers better electrical performance, excellent corrosion resistance without plating, and is ideal for applications where electrical contact quality and non-interference with magnetic fields are important considerations.

Q2: What plating options are recommended for different applications?
We recommend nickel plating for general applications requiring good corrosion resistance and durability, tin plating for excellent solderability and cost-effective corrosion protection, gold plating for superior corrosion resistance and low contact resistance in precision instruments, and silver plating for the highest electrical conductivity in critical current-carrying applications. The choice depends on your specific requirements for conductivity, environmental resistance, and budget.

Q3: Can you manufacture custom binding screw configurations?
Yes, we specialise in custom binding screw solutions including special thread sizes and pitches, unique head designs and configurations, custom lengths and dimensions, special plating requirements, OEM branding and markings, captive designs and special assemblies, and complete custom fastening systems. Our engineering team can develop tailored solutions for specific equipment requirements and design constraints.

Q4: What are the benefits of knurled head screws versus thumb screws?
Knurled head screws provide excellent grip in limited space, more precise torque control, and lower profile designs suitable for instruments and compact equipment. Thumb screws offer faster adjustment, tool-less operation, and easier handling for frequently accessed connections. The choice depends on your specific requirements for adjustment frequency, available space, torque requirements, and user interface preferences.

Q5: How do I select the appropriate binding screw size for my application?
Screw size selection depends on multiple factors including electrical current requirements, wire sizes to be secured, panel thickness and material, torque requirements, available space constraints, environmental conditions, and safety considerations. Our technical team can provide specific recommendations based on your electrical specifications, mechanical requirements, and application parameters to ensure optimal performance and reliability.
