Gould Fasteners is a trusted Canadian source of screws of all types including an extensive selection of self-tapping screws. Self-tapping screws are available in a variety of designs, materials, head types, and finishes appropriate for applications in aerospace, military, electronics, and other industries.

Self-tapping screws is a unique type of screw which can tap their own holes as they are driven into material. With metal, hard plastic, and other hard substrates, self-tapping is possible through a gap cut into the screws’ thread continuity, which generates a flute and cutting edges. On wood, soft plastic, and other soft substrates, the self-tapping capability often comes from a tip that tapers to a gimlet point, in which no flute is necessary; the point forms the hole by displacing surrounding material instead of drilling, cutting, or evacuating, similar to the tip of a nail or gimlet.

While some self-tapping screws also function as self-drilling screws – which operate both as fasteners and as drill bits – it is important not to confuse the two types of components. Self-drilling screws are like self-tapping ones that do not require pilot holes. Whereas self-drilling screws are ideal for fastening sheet metal onto wood or metal frames, self-tapping screws are recommended for metal with a pilot hole.

Gould Fasteners supplies self-tapping screws made from many different materials, including steel, brass, bronze, copper, aluminum, Monel, nylon, nickel alloys, and titanium. The available head types range from flat and headless to button and fillister. Many of the company’s screws are designed to comply with military standards.

To meet the distributor’s high expectations for quality, Gould Fasteners purchases from highly reputed manufacturers, such as ITW Bee Leitzke and Screw Industries. To ensure customer satisfaction, Gould Fasteners employs a team that pre-inspects a statistical quantity of product before they are shipped to customers.
