The large, flat head and underhead nibs provide for clean countersinking, flush with the surface. Predrilling is not typically required. For interior and dry applications only.
Type 17 cutting point: A thread cutting screw for wood with a coarse tapping screw thread and a special long sharp point fluted to capture chips. Type 17 points can also be on Hi-Lo, deep root, deck screws and partical board screws, designed for the manufacturing of face frames on cabinetry. Smooth shank for a tight fit and a Type 17 point eliminates pre-drilling.
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.
