• Designed specifically for fixing timber work to steel sections
• Stainless steel which with good anti-corrosion performance
• Winged point creates pilot hole through the plywood
• Countersunk Head – Sits flush with material
• They feature wings that eliminate the need for pre-drilling in wood
• Type 410 stainless steel can be hardened through heat treatment, giving it the ability to drill through metal. It does not offer the same level of corrosion resistance of either Type 316 or 305 stainless steel.

Self-Drilling Screws (sometimes incorrectly referred to as self-tapping screws) enable drilling without first creating a pilot hole. Self-drilling screws or (SDS’s) are usually used to join materials like sheet metal to other materials, such as metal or wood.
Self-drilling flat-head screw with wings is available in type 410 stainless steel. Wings above drill point provide clearance hole in work piece so it won’t climb up the shank; wings break off as point engages the steel substrate.Type 410 stainless steel is hardened through heat treatment, allowing it to drill through metal.
Fastener SS304/SS316 Body + SS410/420/CS Point, Self Drilling/Tapping Roofing Bi-Metal Screw with SS EPDM Washer
Our bi-metal screw is made by welding stainless steel together with SS420 or carbon steel.
Its head and body is composed of 300 series stainless steel for corrosion resistance, and its point is composed of SS420 or carbon steel hardened for self-drilling and self-tapping.
Our sharp point bi-metal screw drill capacity is up to 1mm+1mm galvanized steel plate without pre-dirlling, which improves work efficiency for projects.
The SuperFix Bi-metal Screws are well tested such as:
· Hardness
· Torque test
· Wring Force
· Tensile Strength
· The shear stress
· Extraction resistance and pull through
· Coating thickness SST (up to 1500 hrs)
If you are looking for fasteners look unique and have their own specialty, we can help you to fulfill market needs and expand competitiveness with those fasteners.
