This decking screw is also called wood screw. Our stainless steel 410 screws do not oxidize and are extra hardened by a special heat treatment. As a result, the chance of them breaking is virtually nil. Pre-drilling in soft wood is a thing of the past thanks to the handy cutting tip. The cutting ribs of the chipboard screws make screwing in easier. The tension of the screw also decreases, so that it remains stronger. For hardwoods such as oak, Garapa hardwood, Kapur and Red Cedar, you always choose our stainless steel screws for Oak and Garapa hardwood. These are specially protected against extreme tannic acids.
Stainless steel A2 quality screws break regularly because the material is softer than galvanized chipboard screws. Due to the stainless steel 410 quality, the screws are just as strong as galvanized steel screws. Fix tightly in the wood and can therefore handle heavier constructions. For example, this chipboard screw is suitable for hanging brackets that carry heavy items from wooden structures.
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.
