Self-Drilling Screws

All Points Fasteners carries an extensive selection of tek type screws. These 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 for HVAC ductwork, solar panels, electrical, and also metal roofing screws for metal-to-metal applications. Tek screws have changed the standards for the value of screws. They look so ordinary, yet they are so handy to have on the job site. 

The values listed above are averages achieved under laboratory conditions and imply no warranty. Appropriate safety factors should be applied to these values for design purposes.

A minimum of 3 factors of safety should be used. Allow at least three full threads to extend beyond material.

The distance from the center of a screw to the end or edge of a metal member shall not be less than three times the screw diameter.

Steel members shall conform to section 2230, A3 of the code. 25ga, 20ga, 18ga-Astm A 653 Grade 33 S.Q. with a minimum of 33,000 psi yield strength. 16ga, 14ga, 12ga-Astm A 653 Grade 50 S.Q. with a minimum of 50,000 psi yield strength.

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.

Because they are ideal for securing thick pieces of metal together, Beam busters are typically best suited to applications such as:

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

Many contractors depend on Tek screws’ strength for reliable connections. Because Tek screws drill their own hole, they produce the ideal hole size. This single operation fastening results in better thread engagement, better alignment and a tighter fit.

Tek screws are also made from high-quality, specially treated steel, and they are cold-forged to ensure uniformity of the screw dimensions and drill point contours. With their durable construction, you can rest assured that Tek screws will provide the strength you need for your application.

Many of the Tek screws we carry are also zinc-plated. This type of finish provides exceptional corrosion resistance as well as increased strength to withstand the most challenging fastening demands and environments.

All of the types of screws we offer are designed to meet industry specifications. All Points works directly with OEMs. We also work with global manufacturers for all of our custom, branded copper and stainless roof nails and metal roofing screws.

Metal Tek roofing screws are crafted from cold-heading quality steel that complies with ASTM A548, Grade 1022. Each roofing screw-type offered meets or exceeds relevant testing standards, including ASTM C954-93, ICBO-AC118, and AISI-CF 92-1, plus are manufactured to SAE J78 for dimensional specifications.

Below you’ll find a large selection of Tek roofing screw sizes and head options. If you’re looking for something a little different, we stock a full selection of other stainless steel roofing screws that could be of assistance. Many contractors are turning to self-tapping roof screws for new materials, and you can be sure of the quality when you work with us.

Self-tapping screws are able to cut their own threads into materials and, unlike bolts, won’t need a matching female thread counterpart, such as a nut.
