TEK® Self-Drilling

All Points Fasteners carries an extensive selection of TEK® type screws. TEK® screws are self-tapping and self-drilling, which means they feature a drill tip with a small carving piece so that there is no need for pre-drilling. They are commonly used as HVAC duct work, electrical and also metal roofing screws for metal-to-metal applications.

The term TEK Screw has become a proprietary eponym. That’s when a brand name becomes the generic term for a product. Other proprietary eponyms you’re probably familiar with are Kleenex, Clorox, and Xerox.

TEK® screws are available in a variety of shank lengths and diameters. Diameter is indicated by a numeric size that runs from #6 to #14, with #6 being the thinnest and #14 being the thickest. The #8 TEK® screws and #10 TEK® screws are the most commonly used.

Tip size is designated with a value of 1 through 5, which indicates the thickness of the sheet metal that the screw can penetrate — 1 represents the thinnest metal and 5 the thickest. The most common TEK® screw tip is TEK® 3. TEK® 4 and TEK® 5 screws are very popular for any projects using thicker metals.

TEK® 1 screws are designed for roofing applications with metal-to-wood connections. These screws include a very tiny drill bit, which means they make a hole with a diameter that is significantly smaller than that of the external threads on the rest of the screw. With the smaller hole, the threads can bite into the material for a secure hold.

TEK® screws are also distinguished by head type. There are two common types of TEK® screw heads:

• Hex washer head: Features a built-in washer to better distribute weights and loads over a wide area. This style is ideal for roofing projects and other heavy-duty applications.
• Modified truss: Features an oversize dome head and a flange to create a larger area under the head for greater bearing surface.

Most other TEK® screws have a Phillips head style to help drive the screw in straight.

Many TEK® screws are also zinc-plated to provide enhanced durability in harsh environments and applications.

Using TEK® screws in your projects provides a variety of benefits, including:

• Time savings: Because there is no pre-drilling necessary, you’ll have fewer steps to complete.
• Durability: TEK® screws are designed to withstand extreme conditions and all types of use.
• Corrosion resistance: TEK® screws are made from corrosion-resistant materials such as stainless steel.
• Easy cleanup: There will be no shavings from pre-drilling, leaving you with less to clean up.
• Versatile: With their wide range of types and sizes, TEK® screws can serve well in almost any project.
