Self-Tapping Screws:

Self-tapping screws are versatile fasteners that are used across a range of industries.

They’re particularly effective for HVAC installations, where they secure ductwork and other components without the need for pre-drilling holes.

In the automotive industry, self-tapping screws are used in bodywork and interior trim, providing efficient fastening without the risk of material damage.

These screws are also commonly found in electronics casings and furniture assembly, making them ideal for products that require lightweight yet secure attachment in materials such as aluminum, brass, plastics, and fiberglass.

Type A: Being Replaced By Type AB

Type B: Always use pilot hole . You can use a fine-thread Type B screw for non-ferrous lightweight and heavy metals, plastics, resin plywood and other materials.

Type AB: Type AB screws are thread forming screws similar to both Type A and Type B points. It has the pointed tip of a

Type A point screw but the threads of a Type B point screw. This combination makes them ideal for thin sheet

metal, resin plywood, composite materials and several other industry-spanning applications.

Self-Drilling Screws (TEK Screws):

With their integrated flute, self-drilling screws are the go-to solution for construction and roofing applications. They are widely used in structural framing and metal cladding, securing elements like metal decking and insulation panels

with ease. These screws eliminate the need for pre-drilling holes, which significantly reduces labor costs and time on site.

Their ability to drill and tap simultaneously makes them the preferred choice for steel frameworks, particularly in industrial and commercial buildings where speed and efficiency are critical.

Suitable for metal, plastic and wooden material applications and minimize the amount of build-up or foreign debris common in pre-drilled holes.

Self-Piercing Screws (ZIP Screws):

Self-piercing screws, also known as ZIP screws, are used in highly specialized applications.

Their sharp tips make them ideal for precision engineering tasks, particularly in industries like telecommunications, electrical installations, and HVAC ducting.

These screws are perfect for fastening both thin and thick sheet metals, as they can pierce the material without the need for a pilot hole.

In industries such as automotive assembly and sheet metal fabrication, ZIP screws provide the reliability and precision required in fast-paced, high-stakes environments.
