Self-drilling screws, often referred to as Tek screws, are equipped with a drill bit-like tip that enables them to drill through metal and other hard materials. These screws are typically made from high-strength materials such as carbon steel or stainless steel, which grant them exceptional durability and resistance to corrosion. Self-drilling screws come in various sizes and lengths, suitable for different applications, from roofing and siding to metal framing and vehicle construction.

Self-tapping screws, developed in the mid-20th century, eliminated the need for pre-drilling holes. These screws have a sharp point that cuts its own thread as it is screwed into the material These screws have a sharp point that cuts its own thread as it is screwed into the material These screws have a sharp point that cuts its own thread as it is screwed into the material These screws have a sharp point that cuts its own thread as it is screwed into the materialtek screw types. Self-tapping screws are commonly used in drywall, furniture assembly, and other applications where pre-drilling is not practical.

Torque specifications are another key consideration. Proper tightening of bolts ensures a secure connection and prevents loosening over time. Torque values are usually provided by the bolt manufacturer, taking into account factors like bolt size, material, and lubrication Torque values are usually provided by the bolt manufacturer, taking into account factors like bolt size, material, and lubrication Torque values are usually provided by the bolt manufacturer, taking into account factors like bolt size, material, and lubrication Torque values are usually provided by the bolt manufacturer, taking into account factors like bolt size, material, and lubricationfoundation bolts specifications. It's crucial to adhere to these specifications to avoid over-tightening, which could lead to bolt failure, or under-tightening, which may compromise the structural integrity.
