CSK Six Lobe And Rib Self Drilling Screw

The CSK Six Lobe And Rib Self Drilling Screw is a fastener featuring a specific combination of head, drive, and point geometry. The countersunk (CSK) head is designed to sit flush with the surface of the material upon installation. The dual-drive head incorporates both a six-lobe (Torx) and a rib (slotted) drive, accommodating two types of tools for application flexibility. The self-drilling point allows the screw to drill its own pilot hole and form mating threads during installation, eliminating the need for a separate drilling step. The specification is ST3.5-20*40, where 3.5mm is the nominal thread diameter, 20mm is the thread length, and 40mm is the total length. It is manufactured from SUS410 stainless steel, a material known for its strength and corrosion resistance. The product has a Brightening surface treatment, resulting in a clean, metallic finish.
