The choice of M20 foundation bolts is influenced by several factors. These include the weight and type of machinery, the expected dynamic loads, and the soil conditions at the site. The M20 bolt, due to its medium-large size, offers a good balance between strength and ease of installation The M20 bolt, due to its medium-large size, offers a good balance between strength and ease of installation

It’s particularly useful in sunscreen as it has impressive UV resistance and helps block the sun’s UVA and UVB rays from reaching your skin (6Trusted Source).
Titanium dioxide (TiO2) is a chemically inert inorganic compound and an insoluble white solid that occurs naturally in several minerals, including rutile, anatase, and brookite. It is created synthetically from the mineral ilmenite. It is an insoluble white solid. Anatase, when compared to brookite and routine, has the most industrial applications, but it is the most toxic form of TiO2.

Currently, titanium dioxide as a food additive is classified as GRAS, or “generally recognized as safe.”
Titanium dioxide is a common pigment, and zinc oxide and magnesium oxide are common fillers in rubber base adhesives.

There’s also concern that exposure to the mineral over time, even in small amounts, can build up in the body, particularly in the kidneys, spleen and liver. Although most of the mineral is excreted in feces, there is evidence that a small percentage may remain in bodily organs.
Overall, the Food Directorate's comprehensive review of the available science of TiO2 as a food additive showed:
The International Agency for Research on Cancer (IARC) has listed titanium dioxide as a Group 2B carcinogen — an agent that may be carcinogenic but lacks sufficient animal and human research. This has caused concern for its safety in food products (11, 12).
The risks associated with titanium dioxide exposure depend on a variety of factors, including the form of the mineral, the route of exposure (such as being inhaled or consumed), and the duration and intensity of exposure.
Titanium dioxide is produced in two main forms. The primary form, comprising over 98 percent of total production, is pigment grade titanium dioxide. The pigmentary form makes use of titanium dioxide’s excellent light-scattering properties in applications that require white opacity and brightness. The other form in which titanium dioxide is produced is as an ultrafine (nanomaterial) product. This form is selected when different properties, such as transparency and maximum ultraviolet light absorption, are required, such as in cosmetic sunscreens.
