The 5/16"-18 x 2 1/2" Thread Cutting Screws are designed to cut its own threads into the base material as it is driven in, making it ideal for metalworking applications such as sheet metal. The 6-lobe drive allows for high torque installation with a flat head for a flush, countersunk finish. The Type F design includes sharp threads and a tapered point, ensuring strong, secure connections in metal. The zinc plating provides moderate corrosion resistance while maintaining durability.
