The Hexagonal Flange Self-Drilling Screw is a fastener featuring a hex flange head and a self-drilling point. The flange head design provides an increased bearing surface for stable clamping, while the hexagon allows for high-torque driving with wrenches or sockets. The drill point tip eliminates the need for pre-drilling by cutting its own hole during installation, combining drilling, tapping, and fastening into one operation. This screw is commonly used for connecting metal sheets and profiles. The specification is 1/4-14*70, where 1/4" is the nominal thread diameter, 14 indicates the number of threads per inch, and 70mm is the overall length. It is manufactured from 1022A carbon steel with a Dacromet surface treatment, a coating known for its corrosion-resistant properties. The single piece weight is 13.75 grams.
