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.

Tek screws, a brand name associated with self-drilling screws, are designed for quick and efficient assembly without the need for pre-drilling, which significantly reduces labor costs and time on job sites. The 13mm wafer head variant is characterized by its unique flat, wide head that provides a larger bearing surface. This design not only helps in distributing the load evenly across the material but also minimizes the risk of surface damage, making it ideal for use in visible applications.

One of the key advantages of self-drilling screws for heavy steel is their ability to save time and labor costs. Traditional screws require pre-drilling a hole before fastening, which can be time-consuming, especially when working with heavy steel materials. Self-drilling screws eliminate the need for this extra step, allowing for quick and efficient installation. This is particularly important in industrial settings where production timelines are tight and every minute counts.
