Self-drilling screw is a screw that can tap its own hole as it is driven into the material. For hard substrates such as metal or hard plastics, the self-drilling ability is often created by cutting a gap in the continuity of the thread on the screw, generating a flute and cutting edge similar to those on a tap. Thus, whereas a regular machine screw cannot tap its own hole in a metal substrate, a self-drilling one can (within reasonable limits of substrate hardness and depth).

Fasteners are widely used for many industries, such as construction, vehicle, railway, furniture and some other precision industries. screws,are available in a wide variety of head styles and finishes to fit the demands of nearly any application. These screws are usually used to join materials like sheet metal.

Advantages:
◈Teks Drill Point
Non walking, cutting edges, pigtail reduction
Engages material faster, drills with less effort, safer installation

◈Load bearing area
Selectively hardened to retain strength and ductility performance similar to a Grade 5 bolt
Resists shear failure due to loading and different expansion coefficients in dissimilar metals

◈Installs faster
Drills and taps faster with fewer stalls
Reduces installation time and money

◈Climaseal ACR
Coating provides long life protection
Fewer replacements
