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.

This expansion generates a powerful frictional force that locks the anchor in place, providing exceptional holding power.
