Chemical anchors consist of a two-part adhesive system that typically includes a resin and a hardener. When mixed, these components create a chemical bond that secures the anchor within the substrate, be it concrete, masonry, or other materials. This bond is not only strong but also resistant to various environmental factors, making chemical anchors suitable for both indoor and outdoor applications.

Furthermore, given their often-corrosive-resistant coatings, these screws are especially suitable for outdoor applications where exposure to moisture and harsh weather conditions are concerns.

Moreover, electronics and manufacturing sectors frequently utilize washer head machine screws for securing casings and components. The precision fit and enhanced grip provided by these screws help maintain the integrity of electronic devices, ensuring they function correctly over time.

Various types of expanding plastic screw anchors are available in the market, each designed to accommodate different weights and materials. The most common types include
