This lightweight screw was made through the Phillips Screw corporation. The design involves four curved wings, which could be regarded an enhanced Model of the Phillips screw head.
knowledge the various variety of screw head types is critical for choosing the proper fastener for almost any task. Common types incorporate slotted, Phillips, and Torx, Each individual designed for different applications and purposes. even though slotted screws are Among the many oldest and most elementary, demanding an easy flat-blade Instrument, Phillips heads are made to center the motive force and limit cam-out.
