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.

Another advantage of galvanized wedge anchor bolts is their ease of installation. The wedge design allows for quick and easy insertion into the hole, and once the nut is tightened, the wedge expands to create a secure grip on the material being secured. This makes them a popular choice for contractors and do-it-yourselfers alike, as they can be installed quickly and without the need for specialized tools or equipment This makes them a popular choice for contractors and do-it-yourselfers alike, as they can be installed quickly and without the need for specialized tools or equipment This makes them a popular choice for contractors and do-it-yourselfers alike, as they can be installed quickly and without the need for specialized tools or equipment This makes them a popular choice for contractors and do-it-yourselfers alike, as they can be installed quickly and without the need for specialized tools or equipmentgalvanized wedge anchor bolts.

Long tek screws, also known as 'decking screws' or 'structural screws,' are engineered to provide superior holding power and resistance against various environmental factors. Their length, which exceeds that of standard screws, enables them to penetrate deeply into materials, creating a robust and secure connection. This makes them ideal for tasks requiring substantial load-bearing capacity, such as in construction, woodworking, and machinery assembly.
