What is a bi-metal screw?
A bi-metal screw is a fastener made from two different metals, combining the strength of one metal (like steel) with the corrosion resistance or special properties of another (like stainless steel). This design ensures durability, strength, and adaptability for use in harsh environments like marine, construction, or chemical industries.
What screws to use for thick metal?
For thick metal, use self-drilling screws (Tek screws) with a built-in drill bit tip to penetrate without pre-drilling. Alternatively, use machine screws with pre-drilled and tapped holes or high-tensile bolts and nuts for extra strength. Choose hardened or stainless steel for durability and corrosion resistance.
Could you provide free samples?
For new customer, We can provide free samples for standard fastener, But the clients will pay the express charges. For old customer, We will send you free samples and pay express charges by ourself.
