Bi-Metal self-drilling tapping screws that provide the corrosion resistance of 300 series stainless steel and the efficiency of drill screws. Such screws avoid the shortcomings of each of these materials.
The whole screw is protected with a silver slide coat. This coating not only adds additional corrosion protection it also reduces the screw in resistance.
This screws can be used for up to two sheets of 1.00mm stainless steel (2.00mm total thickness). The hardened point cuts through the steel then the 304 screws are designed to last a long time without corrosion and can also be used with 316 sheet or cladding. This is a much better option than either a carbon steel screw or a 410 stainless screw that will be at risk of corrosion.
