In the realm of academic research, the use of double-threaded studies has emerged as a powerful tool for enhancing the quality and efficiency of research findings. This approach involves conducting two separate but related studies simultaneously, each with its own set of variables and hypotheses. By comparing the results of these two studies, researchers can gain a more comprehensive understanding of the phenomena under investigation and reduce the potential for errors or biases that may arise from single-threaded studies.

The primary structure of a wedge-type anchor consists of a threaded rod, a nut, a washer, and the wedge itself. The threaded rod, often made from durable materials like steel or stainless steel, is inserted into a pre-drilled hole. As the nut is tightened, the wedge is forced against the inner wall of the hole, causing the anchor to expand. This expansion generates a powerful frictional force that locks the anchor in place, providing exceptional holding power.
