Steel and stainless steel self-drilling and self-tapping screws

Self-tapping and self-drilling screws are fastening elements designed to simplify assembly by eliminating the need for pre-drilling. Their key feature is the ability to create threads directly into the material during installation, making the fastening process quicker and more efficient.

BULL-VIT offers a comprehensive range that includes: self-tapping screws, ideal for pre-drilled materials or softer substrates such as plastic or thin sheet metal; and self-drilling screws, featuring a drill point that allows them to drill and thread into metal surfaces in a single step.

BULL-VIT’s screws are available in different materials and finishes to meet various application requirements: white zinc-plated low-carbon steel (C15) for general use; A2 and A4 stainless steel for outdoor environments and more demanding conditions requiring enhanced corrosion resistance.

The dimensional range covers diameters from 2.2 mm to 6.3 mm and lengths up to 80 mm. Screws are available with cylindrical, countersunk flat, hexagonal flange, and pan head with washer, ensuring maximum versatility for a wide range of applications.

All BULL-VIT’s self-tapping and self-drilling screws strictly comply with UNI, DIN, and ISO international standards, guaranteeing regulatory compliance and the reliability needed for industrial applications.
