Self drilling screws

Product Description

Ezzy Hardware Stores are Importers of PATTA Self Drilling Screws in Hex, Pan, CSK and Truss Heads. Why use PATTA Self Drilling Screw? PATTA Self-drilling screws mainly has three advantages as following: Firstly, PATTA Self Drilling Screws can save labor. Drilling hole, forming mating thread and clamping home can achieve in an easy operation. It doesnt require for difficult alignment of two or more elements. Secondly, self-drilling screws can save materials. It only needs one tool for application---screw drive. Power drills, drill bits and elaborate and costly press tools and their maintenance are eliminated. Finally, self-drilling screws can improve product quality. It ensures correct hole size every time, resulting in better thread engagement and tighter clamp PATTA 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 pullout performance and minimizes backout. PATTA 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 corner is created to scrape the steel off. Sufficient pressure has to be applied for more effective drilling making drilling tiring. PATTA non walking drill point provides fast material engagement. PATTA Hex Head Self Drilling Screw comes with EPDM washers which provide excellent heat, cold, weather, Ozone, Oil resistance and very good bending strength, wear resistance, repulsive elasticity and compression strength. PATTA Self Drilling Screws are engineered for fast drilling and smooth tapping with less effort. PATTA Self Drilling Screws comes in both Zinc as well as Ruspert® Coating (Anti-Corrosive). Ruspert® metal finish is a non-organic, high grade metal surface processing technology that prevents corrosion. It consists of three layers: the first layer; a metallic zinc layer, the second; a high grade anticorrosion chemical conversion film, and a 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. Features: * Superior corrosion resista
