Due to their unique advantages, 2% self-drilling screws find applications in a wide array of sectors. In the construction industry, they are regularly used for securing metal roofing and siding, providing a strong hold that withstands weather elements. In the automotive industry, these screws assist in assembling parts securely without compromising the integrity of the materials involved.

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.

Countersunk self-drilling screws are a specific type of screw designed to allow for a flush finish in various materials, including wood, metal, and plastic. The term countersunk refers to the conical shape of the screw head, which allows it to sit seamlessly against the surface of the material being fastened. This design is particularly advantageous for aesthetics and functionality, as it eliminates any protruding heads that could be prone to snagging or catching on other objects.

3. Thermal Expansion Materials expand due to heat. When temperature variations occur, the differing rates of expansion between the anchor bolts and the material they are affixed to can create stress, leading to loosening. This is especially common in environments with extreme temperature fluctuations.

The versatility of these bolts allows them to be manufactured in various sizes and specifications, accommodating the specific needs of each project. They can be produced as anchor bolts, tie rods, or any other configuration required to meet the engineering demands.
