TEK® Screws

All Points Fasteners carries an extensive selection of TEK® 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 commonly see use as electrical and roofing screws for metal-to-metal applications.

TEK® Screw Specifications

TEK® screws are available in a variety of shank lengths and diameters. Diameter is indicated by a numeric size that runs from #0 to #15, with #0 being the smallest and #15 being the largest. 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 roofing applications and for use in any product that you will be regularly rebuilding or taking apart for maintenance, such as air conditioning units.

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.

Benefits of TEK® Screws

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.

Beam Buster TEK® Screws

The longest drill point available is the TEK® 5, or the “Beam buster” screw that’s designed for exceptional ease when fastening two materials together without predrilling. Beam busters are fully threaded, Zinc plated and some of the strongest roofing screw types around. We stock 1-1/4”, 1-1/2” and 2” models in cases of 2,000.

  • Barn and carport construction.
  • HVAC system installation.
  • Metal roof installation and repair.
