chemical fixings for concrete

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.

The design of the hex head self-drilling screw is a testament to engineering ingenuity. The threaded shank not only secures materials together but also drills its own hole as it is driven in. This eliminates the need for separate drilling and screwing steps, saving time and effort on the job site. The unique thread design enables it to cut into metal, wood, or composite materials with ease, making it a versatile tool for diverse applications.
