Automakers are often the driving force behind the latest product and process innovations in assembly. Case in point: European automakers have been using flow drilling screws since 1996 to assemble body panels and chassis made of aluminum and thin materials-which continue to gain favor to make cars lighter.

A tool manufacturer partners with technical colleges to teach assemblers and maintenance personnel how to apply torque to threaded fasteners.

In today’s economy, manufacturers must find ways to assemble more product with less labor. As a result, they are increasingly using fully and semiautomatic screwdriving equipment to boost productivity and improve quality.

Unlike conventional riveting, self-piercing technology does not require a predrilled hole. Rather, the rivet makes its own hole as it is being inserted. 

New technology gives impact wrenches the ability to measure torque and angle.

The most common method of checking a bolted joint is generally referred to as a "torque audit," which measures a value know as "residual torque."
