Sharx screws are designed to bite and hold fast in stubborn materials. Sharx are specially engineered with high/low thread form, incorporating indentations, or "teeth." The teeth easily cut through high-density materials and resist back-out even after prolonged vibration.

Sharx Marine Screws are all Phillips Drive, available in Flat Head, Pan Head, and Oval Head. These screws hold fast in fiberglass, plywood, and wood substitute materials, and are ideal for applying trim, rub rail, and molding to fiberglass boat hulls. Made from 316 stainless steel, they are perfect for projects exposed to harsh marine or chemically caustic conditions.

Screws up to 1" in length are fully threaded. Screws more than 1" long are threaded 2/3 of shank length.
