In the automotive industry, T-head screws are regularly employed in assembling components like engine mounts and chassis parts, where stability and strength are paramount. Furthermore, in machinery, they are often used in conjunction with nuts or T-nuts to secure fixtures and equipment which require tight and reliable connections.

Expanding metal wall anchors are designed to hold heavy items by distributing the load across a larger area within the wall. They typically consist of a metal sleeve that expands when a screw is driven into it. This expansion action grips the surrounding material, creating a solid anchor point that can support significant weight. They are particularly useful in scenarios where traditional screws might loosen over time, such as in drywall installation or when hanging items from concrete surfaces.
