100 Pieces Gypsum Screw Fine Threaded Black 3.5*1'

Self-tapping screws are fasteners designed to join materials without the need for pre-drilled holes, although using a pilot hole can improve accuracy and ease of installation. They are commonly used in metal and plastic applications due to their high tensile strength, which provides durability and the ability to withstand higher torque during fastening. These screws can be removed and reused if necessary and are available in various head types, such as round and countersunk, to suit different applications. Depending on their length and the angle of insertion, self-tapping screws can typically support loads of approximately 80 to 100 pounds.
