Frequently Asked Questions (FAQs)

Why are they called TEK screws?

"TEK" is a trademarked name originally developed by ITW Buildex for self-drilling screws. Over time, the term became genericized in the industry. TEK screws feature a hardened drill point (sizes #2 to #5) that allows penetration into metal without pre-drilling, combining drilling and tapping into a single operation.

What is the difference between a standard screw and a TEK screw?

Standard screws require pilot holes and rely on pre-tapped threads. TEK screws, however, have a sharp, flute-like tip that cuts through materials like steel sheeting, saving labor and improving installation speed. They are especially effective in metal-to-metal fastening applications.

Why do construction workers use nails instead of screws?

Nails are preferred in framing and structural woodwork because they offer greater flexibility under load and are less prone to brittle failure. They absorb shear forces better than screws and allow slight movement without breaking—important in seismic zones or buildings subject to thermal expansion.

What is the main advantage of TEK screws?

The primary benefit is efficiency: TEK screws eliminate the need for separate drilling and tapping tools, reducing installation time by up to 50%. They also provide superior holding power in thin-gauge metals and composite materials, with excellent vibration resistance.

How can I verify a fastener supplier’s reliability?

Check for ISO 9001 certification, request third-party inspection reports (SGS/Bureau Veritas), analyze on-time delivery records, and conduct sample testing for tensile strength, thread integrity, and coating adhesion. Reorder rates above 20% are a strong indicator of trustworthiness.
