All self-drilling screws offer economical benefits: reduces labor and tooling costs; reduces or eliminates drill bits and taps. As with all types of self-drilling screws, This Phillips flat undercut head self drilling screw creates its own treads when driven into material preventing the need to drill an additional pilot hole. The undercut feature on the flat head allows for extra threading which is critical for the smaller length self drillers. Flat screw heads are among the most common types. When used with wood, they lie flush with the surface of the material. They can also be driven to the bottom of a counterbore and hidden with a plug, making them well-suited for applications where itâ„¢s desirable to have no visible screws. Another benefit of using flat head wood screws is that they help to maintain the integrity of the material. They can countersink and seat flush without causing splintering or other damage. The 18-8 stainless drill screw offers superior corrosion resistance while the 410 stainless screw will drill through harder material than the 18-8. The hardness of the material to be drilled should be a minimum of 10-20 Rockwell hardness points less than the screwâ„¢s hardness. Minimum torques are the same for stainless and steel self-drill screws. Drill time is 2.5 seconds for a 1mm thick plate.
