Self Drilling Screws Features :


Drill Point which has precise cutting edges to improve drill performance with less EFFORT. The Unique Point to thread design extrudes the metal preventing strip-out and maximizes pull out performance and minimizes back out. Drill Point has a unique curved edge at the corner of the drill point.

This ensures that the drilling process becomes self-digging making drill penetration effortless. The conventional drill point only facilitates drilling.

A knife like a corner is created to scrape the steel off. Sufficient pressure has to be applied for more effective drilling making drilling tiring.

Self Drilling Screws comes in both Zinc as well as Ruspert® Coating (Anti-Corrosive), Epoxy Polymer Coating, Xylan Class 3 Coating.


Rupert® metal finish is a non-organic, high-grade metal surface processing technology that prevents corrosion. It consists of three layers :


First layer; a metallic zinc layer

Second; a high-grade anticorrosion chemical conversion film

Third outer layer; baked ceramic surface coating.


The distinguishing feature of Ruspert® is the tight joining of the baked ceramic surface coating and the chemical conversion film. These layers are bonded together through chemical reactions and this unique method of combining layers results in a rigid combination of the coating films. Ruspert® treatment does not attribute its anti-corrosion properties to merely a single material, but the synergy of these three layers, which combined have superb rustproof qualities. Compatible with metal coated and painted surfaces, fasteners coated with  Ruspert® are resistant to acid and alkaline attack, galvanic corrosion and hydrogen embrittlement. These fasteners conform to corrosive gas test standard (Kesternich) DIN50018 SFW-0.25 and give a Salt  Spray Fog Test to exceed (JISZ2731) 504 Hours.
