We support OEM/ODM services for clients needing custom sizes, head styles, coatings, and drill-point types. Our team ensures reliable supply, responsive service, and competitive pricing for bulk orders.
- Head Styles: Hex washer head, pan head, truss (wafer) head, and flat head options available with Phillips, Pozi, Torx, or hex drives.
- Drill Points: Tek #1 to Tek #5 available. Higher numbers drill through thicker metal (Tek 5 up to 1/2” steel).es.
- Materials: Hardened carbon steel and stainless steel (410, 304, bi-metal).
- Strength: High tensile and shear capacity, suitable for metal-to-metal fastening.
- Coatings: Zinc, Ruspert®, Geomet®, hot-dip galvanizing, and color-painted heads for corrosion resistance and aesthetics.
Tek screws excel in many construction and industrial scenarios that involve fastening metal components quickly and securely. Their self-drilling capability (integrated drill-bit tip) eliminates the need for pre-drilling, which speeds up installation in metal-to-metal or metal-to-wood connections. Below are typical applications of Tek screws, backed by industry sources:
- Metal Roofing and Cladding: One of the most common uses of Tek screws is fastening metal roofing panels and exterior cladding to structural members. These screws (often with hex heads and sealing washers) quickly drill through metal sheets into purlins or studs, creating a weather-tight seal for roofs and walls. Roofing Tek screws are designed to attach metal panels to both steel and wood framing as needed, and often have bonded washers to prevent leaks. Their corrosion-resistant coatings make them suitable for outdoor exposure.
- Electrical Installations: Electricians frequently use Tek screws to mount electrical components to metal structures. These screws make it easy to attach junction boxes, conduit straps, panels, and cable trays to steel studs or enclosures without pre-drilling. As one fastener supplier notes, Tek screws are prevalent in “electrical applications”, where they quickly secure metal boxes and supports. They save time when installing conduit and fixtures on metal framing, acting as “metal-to-metal” fasteners that ensure a tight, conductive connection.
- Manufacturing and Assembly Lines: Outside of building construction, many manufacturing facilities use Tek screws for product assembly. These fasteners enable rapid, one-step joining of metal parts in appliances, vehicles, and equipment. Because Tek screws drill their own pilot hole, they streamline production – manufacturers can drive them in quickly and consistently. As one source explains, manufacturers rely on Tek screws for “rapid assembly” to maintain a steady production pace, since the screws create their own threads in the material
Q: Are tek screws different from self-tapping screws?
A: Yes. Tek screws have a self-drilling tip (it looks like a small drill bit) that can cut its own hole, eliminating the need to pre-drill a pilot hole. Standard self-tapping screws, by contrast, can form threads in material but still require a pre-drilled hole. In short, all tek screws are self-tapping, but they also self-drill, which makes installation faster and easier.
Q: What materials can tek screws fasten?
A: Tek screws are designed primarily for metal-to-metal fastening. They are commonly used to join steel-to-steel or aluminum-to-steel, such as thin-gauge steel framing, metal roofing to purlins, or fastening sheet metal ducts. Some tek screws (especially winged tek screws) can also be used for wood-to-metal applications – for example, attaching plywood or lumber to metal, as the wings will ream the wood then break off when the screw reaches the metal. In general, tek screws are ideal for steel, aluminum, and other metals, and in certain cases can work with wood or plastic layered with metal.
Q: What are the common tek screw head types?
A: The most popular head styles for tek screws are hex washer heads, pan heads, truss (wafer) heads, and flat heads. Hex washer heads (external hex drive) are widely used for heavy-duty jobs like roofing and steel framing because they allow high torque and often include an integrated washer. Pan and truss heads (usually with Phillips, Pozi, or Torx drives) are lower-profile options useful for thinner metal attachments or where a smoother finish is desired. Flat heads (countersunk) are used when you need the screw to sit flush with the surface.
Q: Which coating is best for corrosion resistance on tek screws?
A: For outdoor or harsh environments, stainless steel tek screws or those with premium anti-corrosion coatings are recommended. For example, 410 stainless steel tek screws provide good corrosion resistance with high strength, while 304 (18-8) stainless screws offer superior corrosion resistance (especially against rust) for long-term outdoor use. Among coatings, Ruspert® and Geomet® are excellent choices for steel screws – Ruspert is a ceramic multi-layer coating proven to resist corrosion in salt spray tests up to 1000+ hours, and Geomet is a zinc-aluminum flake coating that is chrome-free and durable. Hot-dip galvanized tek screws are also used for heavy corrosion protection (thick zinc layer, often for roofing and exterior steelwork). The best choice depends on the environment: stainless or high-grade coated screws for coastal, acidic, or humid conditions, and standard zinc-plated screws for dry indoor use.
Q: Can I request custom tek screws for a specific application?
A: Yes. Fong Prean offers custom manufacturing for tek screws to meet your specific needs. Through our OEM/ODM services, you can specify non-standard lengths, diameters, head designs (even special drive recesses), drill-point styles, thread pitches, as well as specialized coatings or finishes. We have an in-house R&D team and modern production facilities to develop custom screws, even patented designs, that align with your project requirements. Whether you need a unique head marking, a particular corrosion-resistant coating, or packaging with your branding, we can accommodate those requests. Feel free to contact us with your requirements, and we will work on a tailored fastening solution.
