SuperFix Bits are designed for the most demanding applications in trade and industry. They are designed to have the ability to transfer high torque loads, safe to use and extremely durable. The greater elasticity of tough viscous bits prevents premature breakages of the tip of the tool.
Threaded screwdriver bits work with the Right Angle Drill Attachment and/or Extensions for close-quarter installations.
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:
· Torque test
· Wring Force
· Tensile Strength
· The shear stress
· Extraction resistance and pull through
· Coating thickness SST (up to 1500 hrs)
