The primary function of wedge bolts is to firmly attach the wooden or metal forms to the concrete foundation or structural steel. This ensures that the forms maintain their position during the pouring and setting of the concrete, preventing any displacement or leakage that could compromise the integrity of the structure. The bolts' ability to withstand high tensile forces is critical in withstanding the pressure exerted by wet concrete and the subsequent curing process.

Moreover, these screws are highly versatileself embedding head screws. They can be used in soft materials without fear of stripping, and in harder materials, they can create threads that are stronger than the base material itself. This versatility has made them indispensable in industries where lightweight yet robust solutions are sought, such as in the manufacture of electronic devices or in aerospace components.

Expanding plastic screw anchors, often referred to as wall anchors, are designed to secure objects by expanding as a screw is driven into them. Typically made from durable plastic, these anchors are inserted into a pre-drilled hole in the wall. When a screw is inserted into the anchor, it pulls the anchor wings outward, gripping the surrounding material tightly. This expansion creates a hold strong enough to support various weights, making them ideal for a wide range of applications.
