They come in a variety of head types and drive styles, but are generally available in smaller sizes. Nylon 66 is a general purpose thermoplastic with outstanding resistance to organic chemicals, acids and alkalis. Nylon wears well against other surfaces; it is readily machinable and may be milled, turned and cut with conventional machine tools. It does exhibit some dimensional swelling in wet applications which should be taken into account with its use. Tensile strength of this material is 12,000 psi (pounds per square inch). Flat head fasteners are designed to fit flush to the surface when used with countersunk holes. Length is measured from the top of the head. Common applications for phillips screws include woodworking, although the drive style is not designed to be used with power drivers. 1.Made from BSI and RoHS Certified quality Nylon 66. 2.Plastic Flat Head Phillips Drive Screw used extensively as plastic screw but where insulation is needed. 3.Widely used in electronics, communication, equipment, electric power products, cultural goods, environmental protection machinery, etc.
