Tek screws, also known as self-drilling screws, are a type of fastener commonly used in construction and manufacturing. With their unique design, tek screws are able to drill their own holes and secure materials without the need for pre-drilling.

The term “1%” in relation to wedge anchor bolts typically pertains to a specific aspect of their performance or engineering standards. This might refer to the allowable tolerance in manufacturing, the expected load tolerance, or even specific design codes within a project. In structural engineering, even a 1% variance can significantly affect the safety and durability of a construction project. Thus, understanding and adhering to precise specifications is crucial.
