A: Self-tapping screws form their own mating threads as they are driven into a pre-drilled or pilot hole, eliminating the need for a pre-tapped nut or insert in lighter-gauge sheet metal or plastic panels.
A: The title designates it as SLFTPG, which is Genie's abbreviation for self-tapping. The #4-40 designation refers to the thread size (No. 4 diameter, 40 threads per inch UNC coarse thread).
A: #4-40 self-tapping screws are very small. Use a hand screwdriver or low-torque power driver with a clutch setting to avoid stripping the formed threads.
