In addition, the washer head design of these screws provides added stability and support. The larger surface area of the washer head helps to distribute the load more evenly, reducing the risk of the screw pulling through the material or becoming loose over time
In addition to their ease of installation, wedge anchor bolts are also incredibly strong and durable. Once properly installed, they provide a secure connection that can withstand heavy loads and high levels of stress. This reliability makes them a popular choice for a wide range of applications, from securing machinery and equipment to anchoring structural elements in buildings
J-bolts are another type of foundation bolt that features a J-shaped end for securing objects to concrete or masonry surfaces. These bolts are commonly used for securing equipment, machinery, or structural components to a foundation
Materials
Lithopone is manufactured by a process (Fig. 1) in which barium sulfide solution is prepared by reducing barite ore (BaSO 4) with carbon and leaching the resulting mass.

TiO2 comes in many different forms. However, only a few of these forms are considered food-grade (acceptable to be added to food). Many studies that raised concern about the safety of TiO2, including the concern for genotoxicity, used forms of TiO2 that are not considered acceptable for use in food and have different properties than food-grade TiO2. Other studies did use food-grade TiO2, but took steps to break the material down into smaller particles than what would normally be found in food.


Titanium Dioxide Raw Material Tio2 Powder

Titanium dioxide is typically micronized and coated for use in cosmetics products. The micronizing makes this somewhat heavy-feeling ingredient easier to spread on skin, plus a bit more cosmetically elegant. Micronized titanium dioxide is much more stable and can provide better sun protection than non-micronized titanium dioxide.

The availability of other white pigments poses a major challenge for the Lithopone market during the forecast period. Other alternatives to Lithopone include Zinc White, Titanium Dioxide, Calcium Carbonate, Blanc Fixe, and Barytes. The use of TiO2 has reduced the commercial significance of the Lithopone in the pigments industry.
Prof. Matthew Wright, chair of EFSA’s working group on E171, noted: “Although the evidence for general toxic effects was not conclusive, on the basis of the new data and strengthened methods we could not rule out a concern for genotoxicity and consequently we could not establish a safe level for daily intake of the food additive.”
