stainless steel self drilling screws for metal

Tek screws, named after their inventor Tek Screw Corporation, are designed with a unique thread pattern that allows them to tap their own hole in metal, wood, or composite materials. Their primary advantage lies in their ability to provide a secure hold without pre-drilling, saving time and effort on job sites. The 20-inch variant is particularly valuable due to its length, which enables it to penetrate deeper and handle heavier loads compared to shorter screws.

Butterfly screws, also known as toggle bolts, are a type of fastener that features a pair of wings that fold during installation and expand once they are inside a pre-drilled hole. The design allows for a stronger grip on hollow walls, such as drywall, where regular screws might not provide sufficient anchoring. Butterfly screws are particularly useful for mounting heavier items like televisions, where the risk of falling can be a significant concern.

Chemical anchors have become a cornerstone in modern construction and engineering, providing a robust solution for bonding various materials together with exceptional strength and durability. Unlike traditional mechanical anchors, which rely on physical interference to grip substrates, chemical anchors utilize a bonding agent to create a strong connection, making them ideal for a wide range of applications in different environments.
