Screws are externally threaded fasteners used in every industry from MRO and OEM to electronics, oil & gas, construction and marine. Similar to bolts in many ways, screws are usually differentiated because they do not require a nut. (A few styles such as Hex Head Cap Screws do require nuts.) As a wholesale screw supplier, AFT carries over 100,000 different types and sizes including self tapping screws, which don’t require a pre-drilled or pre-tapped hole to knurled thumb screws that can tighten by hand. Many of our types are available to purchase ready-to-use or let AFT custom plate or modify to your specifications. Some modifications include threadlockers, nylon patches, custom threads, custom lengths, drilled holes, painting and much more! Shop our online selection or contact us today for a custom quote.
