Earn 1 PDH / 1 LU|HSW

The session will focus on the following key areas:AIA

Screws. They are everywhere and often overlooked. It is likely because they have been entrenched in construction for millennia and so ubiquitous that it is common to find them on the floor of any jobsite. Although these tiny and often-overlooked mechanisms seem simple, in practice the process of specifying them can be complex, often requiring careful considerations in order to ensure proper performance in cold-formed steel (CFS) connections.  

From drill points and head types to test data and specifications. This presentation will provide a brief history on the evolution of screws and serve as a basic overview of the most common types of screws for CFS applications, performance characteristics and industry standards. 

So, please join us for a riveting refresher on all things screwed so you do not have to bolt on your next connection.
