2. Improved Aesthetics The countersunk head design provides a neat appearance, especially in visible or decorative applications. This feature is vital for projects where aesthetics are as crucial as functionality.
- Furniture Assembly In woodworking, countersunk screws help create smooth, clean surfaces without visible fastener heads, which is critical for high-quality furniture.
1. Speed and Efficiency One of the primary advantages of 13mm wafer head Tek screws is their installation speed. The self-drilling capability means construction crews can install these screws quickly, enhancing productivity on site.
They offer a strong, secure connection while reducing the risk of material damage that can occur with conventional drilling methods They offer a strong, secure connection while reducing the risk of material damage that can occur with conventional drilling methodshex head self drilling. In manufacturing, they find usage in automotive, aerospace, and electrical industries, where speed, strength, and accuracy are crucial.Self-drilling screws, also known as Tek screws, are fasteners that can drill their own pilot holes as they are being installed. This feature eliminates the need for pre-drilling, significantly reducing assembly time and effort. Their design typically incorporates a drill point, which allows the screw to penetrate hard materials, including metal and wood, without additional tooling.
In summary, the introduction of DIN6914/A325/A490 heavy-duty hexagonal structural bolts provides the construction industry with a new level of quality and performance. Its robust design, high-strength properties and compliance with industry standards make it the perfect fastening solution for structural steel applications. Whether you are a contractor, engineer or construction professional, this bolt is sure to meet and exceed your expectations for a heavy-duty hex structural bolt.
Overall, the Food Directorate's comprehensive review of the available science of TiO2 as a food additive showed:
For research published in Archives of Toxicology in 2020, scientists fed one group of mice a solution containing titanium dioxide for one month, and compared it to those that did not receive the additive. They found “the richness and evenness of gut microbiota were remarkably decreased and the gut microbial community compositions were significantly changed” in the titanium dioxide group when compared with the control group. The tests also revealed that the titanium dioxide exposure could cause locomotor dysfunction, or mobility issues “by elevating the excitement of enteric neurons, which might spread to the brain via gut-brain communication by vagal pathway.” The researchers concluded: “These findings provide valuable insights into the novel mechanism of TiO2NP-induced neurotoxicity. Understanding the microbiota-gut-brain axis will provide the foundation for potential therapeutic or prevention approaches against TiO2NP-induced gut and brain-related disorders.”
It's sort of ironic, maybe ironic is the wrong word, that the ingredient in paint that makes your kitchen shiny also makes your Hostess cupcakes shiny, Environmental Working Group's senior vice president of government affairs Scott Faber added.
Titanium dioxide is a food additive that can be found in over 3,000 different products in EWG’s Food Scores database.

Amount: if too little titanium dioxide is added, the distance between particles is too large and there is not enough opacity, while if the titanium content is too high, the particles interfere with each other and poor efficiency is obtained.
They are the only two sunscreen ingredients classified by the FDA as safe and effective. And though titanium dioxide is usually used in mineral sunscreens in the form of nanoparticles, evidence suggests that few, if any, particles penetrate the skin.

Le lithopone a été découvert dans les années 1870 par DuPont. Il a été produit par la Krebs Pigments and Chemical Company, entre autres1. Il se faisait en différents grades, en fonction de la teneur en sulfure de zinc. Les qualités « bronze » et « or » contenaient 40 à 50 % de sulfure de zinc, ce qui les rendaient particulièrement couvrantes2. Bien que ce pigment ait atteint son pic de popularité autour de 1920, il s'en produisait encore annuellement plus de 220 000 tonnes en 1990. Il est principalement utilisé dans les peintures, les pâtes et les plastiques3.
3.Used for coloring rubber products, varnishes, leather, paper, enamel, etc.
The National Cancer Institute tested TiO2 for possible carcinogenicity by the oral route of exposure by feeding rats and mice with TiO2 (size not specified) at doses 25,000 or 50,000 ppm TiO2 for 103 weeks. They concluded that TiO2 was not carcinogenic.Also, the study with rats fed diets containing up to 5 % TiO2 coated mica for 130 weeks showed no treatment-related carcinogenicity. Since the size and other TiO2 properties were not specified or determined, we cannot generalize this conclusion and we have to take into account other possible outcomes of this scenario in different exposure conditions (other size/crystalline structure of TiO2 etc.).
